Gatwing X100 remote pilot certficate for Rodney Pilbrow


Pilbrow Surveying Limited PSL construction earthworks roading surveyors 0800 PSL NOWSeptember 23rd
Rodney received his remote pilot certificate from Gatewing. As you can see the training for the X100 is quite thorough with aspects of aerodynamics, basics of meteorology, and flight rules being taught along with the practical aspects of operating and maintaining the X100.
We have now completed eight successful flights. So far these have been for site plans with only the early trial flight being of stockpiles however next week will see us flying the stockpiles at Bombay Quarry with the X100. This is the role for which it was bought and we are looking forward to it.
The new computer has literally been running hot with the CPU reaching temperatures of 90° Celsius. A larger fan is being installed to remove the excess heat. The software for processing the images  has exceedingly high computing requirements so getting this part sorted out will improve the speed of delivery of product.
An article about our purchase of the X100 appeared in the local newspaper. For a copy of the article contact Rodney.

This clip from You Tube shows some of the plans that have been prepared from images captured using the X100 processed with Photoscan and LISCAD.
Last week Rodney and Esther flew the X100 down to Geraldine on Air New Zealand to do a flight over Ravensdown’s Geraldine Lime Quarry. Using our Smart Fix to survey the ground control points and local survey control made the process very simple. Only a single flight was needed to cover the 50Ha site. We will be providing a site plan showing how the boundaries sit on the ground which will aid the quarry personnel in their planning. We will also have a whiteboard made that they can use to show visitors and for day to day work allocation.

Here is the plan prepared for Ravensdown of their Geraldine Lime Quarry using images captured by our X100. This plan has been supplied as a whiteboard and a PVC print which can be taken outside without having to worry about it getting wet.
We will be flying two further quarries for Ravensdown in the coming week.
Rodney gave a presentation about Pilbrow Surveying, what we do and what the X100 can offer clients to Tonkin & Taylor last week. A similar presentation is to be given to Pattle Delamore Partners Ltd in a couple of weeks. If you are interested in getting such a presentation made for you r company then give Rodney a call on 0800 PSL NOW.

Merry Christmas

December 19th
The end of this year sees us in a far busier condition that the end of last year. Kamil is working full time at the Transpower Albany site for Downer and Rodney is busy with Twomey Construction at the Steel Mill and McRobbie Rd as well as ongoing X100 work. The X100 has made 21 flights since it arrived in September. All topo work at Bombay Quarry is now being done with the X100. We have completed three topographical survey and aerial photo plans for Ravensdown - Geraldine Lime, Greenleaf Lime and Mata Lime. Read Vaughan Chaffey’s comments about our service here. Our other work still continues and we had the pleasure of setting out a new house for Malcolm & Eileen Lumsden in Ohinewai. Read their comments about our service here.
We wish all our current and past clients, work colleagues and friends a Merry Christmas and a prosperous New Year.

This year is off to a busy start. Kamil is well occupied at Downer’s Transpower Albany site. He has been designing the cable duct layouts and these are put into the machine control system on the digger enabling the trench to be dug accurately limiting the costs involved by reducing the need for excess concrete. Rodney has been working since Boxing Day at Wiri for Downer who have been preparing the formation for new rail lines.
The X100 has been in use already this year with a flight at Highbrook. 
Pilbrow Surveying wish to express our sympathy to the family of Roger Taylor who died earlier this month.

Another busy month, though the wet summer has caused many delays for our earthworks clients.
We welcome Gary Mundy and John Moran from G Mundy Construction to our list of clients. We are doing topo surveys, volume calcs and set out for them at Highbrook.
We welcome back McRobbie Bros. as a client. It has been a number of years since we worked for this Pokeno based construction and transport business.
Rodney interviewed Zeeshan William Nasri who is applying for a position with us. Zeeshan then spent a day out on site to see what we do. Pilbrow Surveying Limited have offered a role as Assistant Surveyor to Zeeshan and as soon as his work visa details are completed he will become part of our team. All the best to you for your future with us.
At the end of this month we will mail out the first of our new Good News Report, a bulletin of positive and fun ideas for clients and friends.  Each edition will contain some great ideas that can help you to create more fun, enjoyment and pleasure in your life. If you would like to be added to our mailing list for this please email PilbrowSurveying@xtra.co.nz or ring Rodney on 0800 PSL NOW.

Zeeshan’s work visa has been approved so he is now a member of our little team. Zeeshan (or Shani) will initially be spending time with Kamil at the Downer Albany site. He will be doing as builts so Kamil can concentrate on preparing the data for the machine control systems.
Rodney and Esther made their first trip down to the new Downer project at Apata near Katikati in the Bay of Plenty during this month. This is another job for Kiwi Rail, involving the replacement of an existing rail bridge with box culverts.
We had our first meeting with our new Business Mentor, Ken George, last weekend. Ken will be assisting us with ideas and suggestions to improve the business. The first of these is a questionnaire designed to find out what specific things about us that our clients like or dislike and what they would like to see us doing better. So our existing and new clients can look forward to receiving this soon.

Pilbrow Surveying LimitedApril 22nd
The couple of weeks of fine weather at the start of April has made for a very heavy workload this month. The team has put in some long days to ensure we keep up with our client needs.
For those of you used to seeing our grey Mitsubishi L300 vans there is a shock coming - we have bought a new all wheel drive Volkswagon Transporter - not grey but white. It has been fitted with new boxes specially designed to accommodate the X100 as well as all our other equipment to ensure we always have the right tool for the job at hand.
The second Good News Report will be going out with our accounts this month. There have been very positive comments about this bulletin of positive and fun ideas. We also plan to send out a short email newsletter, the e-PiStLe, at the end of this month. We recently sent out client feedback forms and many clients asked for ways to cut costs. So one item in the newsletter will be ways to save money on surveying. There will also be a story from one of our people. This months story comes from an article that Rodney found in a box of old newspaper clippings that Geoff had collected. The final item will be tips on how to calculate frequently used quantities or hints on using excel. So if there is something that you have always wondered about then let Rodney know and he can include it in a later issue. If you would like to be added to our mailing list for the Good New Report or the e-PiStLe please email PilbrowSurveying@xtra.co.nz or ring Rodney on 0800 PSL NOW.

Winter has arrived again with two weeks of persistent rain putting stop to most earthworks jobs.
We plan on having a stand at the upcoming Quarry Conference and have been busy getting things ready for this. It will be an excellent way for us to showcase what we as a company can do for clients. To emphasis this we have put together a booklet of testimonials gathered from satisfied customers, formalized the client feedback request form, prepared some frequently asked questions and recognized what makes us special as a company in a new client charter. Copies of these will be added to the website as time permits. Copies of these items will be made available to new clients in a pack and all those who wish to get a copy can email us.
Following questions from people over the years we have made up a chart which outlines the relationship between slopes in terms of V:H, percentage and degree from the horizontal. For instance 1V:2H = 50% = 26.57°. The chart shows this for a number of commonly used grades. Anyone who would like a copy of this chart please give Rodney a call.

Rodney and Esther will be at the Quarry Conference in Wellington with a stand highlighting the X100 from 13th to 15th of July. They are looking forward to meeting up with all our existing quarrying friends and hope to meet many new ones. We will be at Site 18. Thank you very much to Synergy Positioning who have loaned us their X100 display for the event.

The Quarry Conference went exceedingly well. Esther and my road trip down to Wellington was blessed with beautiful weather enabling us to get some magic photos of landmarks on the way. (see below). We got into Wellington in the early evening and had to negotiate the traffic with our old NAVMAN unit directing us the wrong way up one way streets. Eventually we found the parking building adjacent to the Amora hotel where the conference was held. To deliver the bits for our stand required taking the van up to the top of the six story carpark then up a further deadly spiral access way to a claustrophibic garage filled with others trying to also deliver stuff. With help from Adrian Mattinson we unloaded our bits and retreated to our hotel. The next morning we were there early to get the stand ready for the show. Over the course of the conference we had many people who were interested in the X100 and what we could produce with it. I was surprised at the number of  people who have had experience with model airplanes. They were keen to compare them with the operation of the X100. Most delegates who spoke with us were impressed with the quality of the images that we are producing. A number of people were attracted by the dual safety and cost effectiveness of the system for stockpile quantification. Esther and I managed to get to a few restaurants over the few days of the conference and really enjoyed our time there. To top off a memorable week we were awarded the Andy Loader Institute of Quarrying Annual Conference Sponsors' Display Award for the best stand at the 2012 Quarry Conference. The photo above shows Esther and I with the trophy which was presented by Andrew Robertson.
This month we also took delivery of our new Leica Viva GPS system. I am much impressed with this system and hope that it gives as good service as the GPS500 which we have had now for 13 years. We can still use the 500 with the new system, as it uses the same radios, so when necessary we are able to use multiple rovers from the same base.

Two new clients and the return of an old one this month:  Todd Potter from Potter Contracting Waikato Limited and Michael Bird from Envirowaste welcome to you both and I hope that we will work together for many years to come. Brian Roche from Ravensdown had us return to Waikaretu this month to update the pit survey.
When we last did the Waikaretu Lime quarry it was a couple of months prior to taking delivery of the X100 so it was great to be able to compare the methods of survey.
During the survey at Envirowaste’s Hampton Downs site we carried out our most flights in a single day yet when we did four. We were asked to provide an orthophoto of a 200 Ha site and extract a DTM of about 60 Ha of the total. Michael told me he was very impressed with the quality of the image produced compared with previous aerial images.
Zeeshan has returned to Pakistan for six weeks but will return toward the end of September.
We will be mailing out the next edition of the Good News Report soon where you will find ways to make every meal a pleasure.  Making the effort to use some of these simple ideas can help to make the normally mundane task of eating a delightful experience.
There are also power questions designed to cause you to experience more happiness, excitement, pride, gratitude, joy, commitment and love in your life.

Zeeshan has returned from Pakistan where he married Anila. The plan is that Anila will join Zeeshan in New Zealand when she finishes her nursing course. We wish them both a long and happy marriage.
During this month we did another X100 survey of an Envirowaste landfill site, this time at Greenmount. Michael Bird from Envirowaste has been using the high resolution images from our flights as a background to his plans.

We have been using the Gatewing X100 for over a year now. In that year we have completed 56 flights for clients and many training flights. After an initial slow start with the X100 jobs our clients have now seen what high quality images are being produced and how these along with the dense DTM’s can help them with planning and visualising their sites. We now have forward bookings for the X100 and look to further expanding this side of the business.
I have been getting inquiries from people around the world who are looking to buy an X100. The questions they have are all very similar so I will be putting together a little data sheet outlining some of the things which you need to consider if you want to buy and use the X100. Any one who wishes to get a copy can email me ( PilbrowSurveying@xtra.co.nz ).
Zeeshan and I travelled down to Bonny Glen Landfill which is just north of Marton to carry out a survey of their site. On the morning of the flights the weather was perfect. From where we were we could see up to Mt Egmont and across to Mt Ruapehu, both snow covered mountains were brilliantly clear against the blue sky. We were assisted on site by Kerry Thompson, the Landfill manager, who showed us around the site making the task of placing the ground control markers much easier.

This has been a very busy month for Pilbrow Surveying.
Kamil has spent nearly three works at night assisting with work on The Base Intersection project with Cambridge Construction. While at the same time continuing his ongoing work for Downer at Albany. To recognize Kamil’s excellent work attitude and commitment we are proud to announce that he is now to be designated “Senior Surveyor”. Kamil will be continuing his interest in machine control systems and will be the company specialist in the preparation of data for such systems.
Rodney has carried out multiple X100 flights at some existing and some new clients. We would like to welcome Chris Sinclair from Millbrook Quarries Ltd and Geoff Thomas from Hick Bros. to our list of clients who have used the X100. Chris had this to say about our service:   “Using the plane is a fast safe way of gathering the data. No people on the Quarry benches at our worksite derisks the survey process.” Rodney was also the guest speaker at the Waikato branch meeting of the Quarry Institute where he gave a talk on construction surveying and the use of the X100 in quarries. This comment from Dean Torstonson about the talk: “The feedback that I received from those that attended was awesome……. A couple have suggested to try and get you in again and capture the ones that did not attend your presentation.”

Kamil and Zeeshan are on holiday over the Christmas break but Rodney is working through.
Rodney and Esther went down to Taupo to carry out an X100 survey of another Envirowaste landfill during this month. An X100 survey was also carried out at the Rainbow Park Nursery in Ramarama. A typical nursery there were lines of trees and other plants everywhere but it was still possible to get the ground level between most of these tree lines to form a model of the underlying ground shape. The data from this survey has been passed along to The Surveying Company for further design work.

A new year has stumbled into being with many people still away on holiday even this late in the month. It appears that many companies are taking the opportunity to reduce outstanding leave allowances.
We have taken on Ela Puchalska who will mainly be responsible for the calculations involved with the photogrammetric processing of the X100 data. Though after two years working for Fulton Hogan on the Te Rapa Bypass she is very capable of doing our normal construction work.
This month we supplied Higgins Waikato with a surface suitable for use on their machine controlled grader. We took the centreline data, which was the only information provided, and prepared a tin of the final road surface which they placed into their system. Preparation of this surface only took a few hours but they now have a complete model of the entire road for grading.
We got a mention in the “Waikato Times” earlier this month. There was an article looking at the expanding use of unmanned aerial vehicles  for various roles and Rodney was interviewed about his experiences with the X100. We have also been mentioned in a recent edition of the Holcim newsletter. The article outlined how the X100 fits perfectly with the introduction at all Holcim sites of a new programme to increase safety around quarry faces and stockpiles.
At the end of last year we carried out another X100 survey of an Envirowaste landfill. This is the fourth Envirowaste site we have surveyed. The Broadlands Landfill is managed jointly by the Taupo District Council and Envirowaste. The site survey has been followed up by some volume calculations using the DTM extracted from the X100 images.
An X100 survey was carried out at the Rainbow Park Nursery at the end of last year. Even with the trees stacked together in dense rows it was possible to extract the underlying ground data. Use this link: https://www.dropbox.com/s/d1t21vhqj414so6/121220%20Rainbow%20Park%20works%20area%203D.pdf to download a 3D pdf which shows the resulting model.

We would like to welcome Richard Scott of Transfield Services to our list of clients. We worked with Richard previously many years ago on the SH20 project. We did some setout and a topographical survey at his Rua Rd site. When Rodney emailed Richard to check if everything was as he had wanted it he had this to say : “Hey there Rodney,  Yeah all the set out on site is great, just as I thought it would be from you.” 
Another new client is Peter Allington from Electrix. He had this to say: “Hi Rodney, Yes it was how we wanted it I'm heading there tomorrow with our geo tech guys to double check everything but on initial inspection it was great. Thanks for the follow up email.”
Thanks for the kind words. Also new this month are Graeme Warriner from Inframax and Elaine Iddon from the Waikato Reginal Council.

Another shortest day has come upon us and the weather is completely grotty. Winds gusting to 110 km/h, well above what we can handle with the X100. So there is a bit of a break which we have been using to get things ready for the Quarry Conference next month. We have been working on a method of measuring stockpiles which we can present to clients who want to get a quick volume of small heaps where it is not economic to get us out to site. Our hope is to have the basics of this sorted before the conference.
We want to welcome Rob Kinney of Rock Pro to our list of clients. Rodney and Ela carried out an X100 survey for Rob of an area near Christchurch. The X100 was packed up and into the big Air New Zealand plane taken down, carried out the survey and back home again that same evening.
We want to welcome Kerry Reilly of Baldwin’s Aggregates. We recently carried out some work for The Surveying Company at Baldwin’s Quarry and now Kerry has had us in to set out for his proposed new plant.
The Field Days were on again last week and Kamil won a hand held GPS unit by being the closest to estimating the coordinates of a post within a fenced off area. The prize was given away by GPS-it, a company specializing in the mapping of kiwi fruit orchards. Well Done Kamil, it shows that accuracy pays off.

I attended the Quarry Conference in Dunedin earlier this month. It was great to catch up with clients that I had only emailed or spoken to on the phone. It is always nice to be able to put a face to a name.
Esther and I have just returned from a few days in the South Island where we carried out aerial mapping of two Ravensdown Lime Quarries. The weather was fantastic and we were presented with amazing views of the Southern Alps. The view from the top of the Geraldine quarry out across the South Canterbury plains to the sea is incredible.
I have had interest in the DIY stockpile measuring system which I mentioned to a few people at the conference. I hope to get some trialing done so keep watch here for updates on how it goes.
The e-PiStLe this month has a funny story about measuring a bridge using the “smoot” as the unit of measurement. Drop me a line if you would like to get a copy.

We have had a busy month. Last year at this time Downer commissioned us to measure seal areas for them throughout the Franklin Region. This year this has been extended to include roads through the Waikato as well. In total 168.2km of road have been surveyed. We got these roads done faster than I had expected by establishing a very efficient work flow. Usually Ela would be out on the sites carrying out the survey, a mornings work would be emailed back to Kamil in the office to do the calculations. Then at the end of the day the afternoons roads would be downloaded ready for calcs the next morning. I would assist Ela with on site work or be out attending to another client.
I want to welcome Peter Kerr from Taraire Developments, Brent Aitken from the Taupo District Council and Ron Spiertz from Ravensdown’s White Rock Lime Quarry to our list of clients. Thank you for using us to do your construction surveying work.
Esther and I are away for most of September visiting with her family. Kamil and Ela will be here to assist with anything that you may require.

Esther and I enjoyed our trip to Europe and are now back to work. Whilst overseas we visited the Aibotix X6 factory in Germany to see how they make their multirotor UAV and also the Leica factory in Heerbrugg, Switzerland. I was very impressed with the testing that goes on for every Leica instrument before it gets delivered to a client. This photo shows a very old GPS unit which was capable of calculating a position in only 9 hours which was a quantum leap in technology from the previous full day but pales when compared with today’s RTK GPS capabilities. Note that the data was stored on a cassette tape in the top left hand corner. The other photo is in the showroom where there are many different total stations on display. My thanks to Ray Copeland of Global Survey for arranging the visit.
Kamil and Ela have had a month of dodging rain and winds to get things done for our clients while we were enjoying much better weather.
I wish to welcome Jeff Hadwin from Cresta Assets Ltd to our list of clients.
This months e-PiStLe has a funny story which Kamil has put together about surveying in Poland. Let me know if you would like a copy.

The earthworks season has started with a roar this year. We have been so busy that I am a bit late with updating this blog. To make things even busier we have had a number of year end stock updates to carry out along with our regular monthly surveys. In the past two weeks we have carried out X100 aerial mapping surveys at  McDonald’s Lime’s Oparure, Otorohanga and Te Kuiti sites, Inframax’s Piopio Quarry and Holcim Aggregates’ Bombay and Taylor’s Lime’s Dunback Quarries. Earlier in the month Ela and I did a pre-works survey of Fletcher’s Rangiriri site and assisted HEB Contractors with pre-works surveys at their Tamahere Cambridge expressway site. During all this Kamil has been busy with Downers and Transfield at three sites around Auckland.
The latest copy of our Good News Report went out at the end of October and I received this very nice email from Neville Thompson, Engineering Manager,  Greenlea Premier Meats Ltd:
Hi Folks.
I have just been overseas for 4 weeks and was nice to find in my bloody BIG pile of mail as usual your Good News Report bulletin.
I always seem to have heaps of invoices, junk mail, and many other leaflet drops, but I always keep your mail to a time I can sit back, relax and enjoy your very useful and helpful reading of your bulletins.
Please don’t stop sending them as I always copy and send to other staff that I fell will benefit and take them home to family as well, Trish isn’t a morning person so I’ll be working on her wake up choices!!!!!
Much appreciated reading.
Regards Neville
Thank you very much Neville. Anyone who would like to go on our mailing list for the Good News Reports or the e-PiStLe feel free to drop me an email or call on 0800 PSL NOW.

Another very busy month for us. We have had to bring the old van back into service so that we can have three gangs out working different sites. Colin has joined us again for the summer and he has already been busy with topographical surveys on HEB Contractor’s Tamahere Cambridge Expressway project as well as coming down to Nelson with me to carry out an X100 mapping of Ravensdown’s Ngarua Lime Quarry in the Takaka Hills. Cambridge Construction Company have begun work on the Te Kowhai Limmer Alignment project just outside Hamilton and Ela has been busy there marking out centrelines, boundaries and lift stakes.
In this month’s E-PiStLe I am starting a series of articles on accuracy limits of commonly used equipment and common mistakes that may occur when using them.

Front of Pilbrow Surveying's 2013 Christmas Card with images of various sites surveyed using oour X100 this year.27 December 2013
This years Christmas Card featured images from various sites which we have surveyed with the X100 this year. I asked “How many of the sites do you recognize from the front of this card?” and put up a prize of a dinner for two to the value of $200 to the first person to correctly tell me where they were.
Keith Miller, Resource Manager, Holcim (New Zealand) Ltd identified all the sites from our Christmas card in a remarkably short time. When I asked Keith how he managed to find the sites so quickly he said: "I recognised a few of the sites straight away, including our limestone quarry at Dunback. The other two South Island quarries were harder, but looked like lime quarries and with help from your website and Google Earth I soon had them identified. The Long Bay subdivision was tricky as the Google Earth images don't show the development and it took a bit of searching to find the distinctive buildings that turned out to be Long Bay College. Many thanks for putting up the prize, which I'm pleased to donate to a worthy cause."


Monthly blog of Pilbrow Surveying LimitedKeith has decided that instead of taking the dinner he will donate the winnings to the Holcim Philippines relief fund.
For all those who were stumped here are the sites (see the image above for the numbering):
1. Hampton Downs Landfill, Hampton Downs, Waikato - Envirowaste
2. Ngarua Lime Quarry, Takaka Hills, Nelson - Ravensdown
3. Dunback Quarry, Dunback, Otago - Taylor's Lime
4. Drury Quarry, Drury, Auckland - Stevenson Resources
5. Rangiriri Expressway, Rangiriri, Waikato - Fletcher Construction Company
6. Long Bay Subdivision, Long Bay, Auckland - WOODS
7. White Rock Lime Quarry, Rangiora, Canterbury - Ravensdown
I hope you had a nice time with family over Christmas and I look forward to working together next year.

We have had an extremely busy start to this year. Ela has been full time at HEB Construction’s Tamahere Cambridge Expressway site with Colin helping her out until he returned to University. Kamil has been kept occupied by various Transfield, Downer and Cambridge Construction sites. Rodney and Esther have been busy with X100 work around the country. We had a record run of X100 flights with seven flights in seven working days at seven different locations. Ranging around from Whakatane, Piopio, Auckland and Dunedin. The total flights for this billing cycle was 12 which is a new high for us.
As you know we are always trying new things and you can see in the accompanying picture one of our trial UAV’s, the CLUC or Chicken Looks Under Clouds.
During this month we had a visit from the CAA to discuss our operation and what changes are being proposed for what they are now calling RPAS, or Remotely Piloted Aerial Systems.
We now have a Facebook and Linked In company page so please follow us  to keep up to date with our goings on.

Another busy month for all of us with continuing work on the construction sites as well as a couple of new sites. We would like to welcome back McRobbie Bros. and The Surveying Company who we have worked for before. New to us are Jack Packer and his Whatawhata Quarry and Roger Walker of Platinum Homes for whom we did site surveys.
We have had a setback this month with the X100 being damaged by a digger. During a flight the unit had an in-flight reset, something which neither us nor the manufacturer has seen before. The X100 glided to the ground after the reset where it unfortunately landed near a digger. The operator did not see it and it suffered irreparable damage to the ebox and body as digging continued. We have been supplied with a new ebox by the manufacturer and are back doing flights again. The logs from the flight have been passed along to the developer of the flight control software to see if they can bring any light to bear on the reason for the reset. The accompanying image shows the state of the X100 after the ministrations of the digger.
Another edition of the e-PiStLe has been sent out today. This has an article on how the area unit the acre came about, some comments on surfaces fro machine control and review of GPS and things to watch out for when using it. If you would like to go on the mailing list for this then email Rodney here

The heavy rain over Easter has led to this spectacular example of bowl failure at one of the quarries which we work. The aerial image shows the bowl shape very clearly while the image with Esther in shows the size of the crack caused when the material moved.
April was another busy month for the low level aerial mapping with sites from Taupo to Whangarei and in between being flown. Mainly re-surveys for existing clients but there were two new sites for new clients.
Hopefully everyone has received their copy of this month’s Good News Report which were mailed out last week. I especially like the article on dealing with those “Garbage Truck” people who go around collecting then dumping their garbage on others and how to deal with such people. If you would like to go onto our mailing list or the email newsletter then give me a call 0800 PSL NOW or email PilbrowSurveying@xtra.co.nz

After many years of faithful service we have sent one of the older Mitsubishi vans to the knackers yard. This was not the oldest of our fleet but it had had an unfortunate experience with a previous employee’s driving abilities so was of no use to us anymore. The 4WD L300 vans were great but are no longer being made hence the change to the all wheel drive Volkswagens we now have.
Rodney and Esther are away for the first week of June to Las Vegas for the Hexagon Conference. This is a showcase for Leica Geosystems products where people from around the world come to have a look. 
This month’s e-PiStLe has a story about the naming of Pilbrows Hill in the Brynderwyns. If you aren’t on the mailing list drop us an email.

Monthly blog of Pilbrow Surveying LimitedPilbrow Surveying Limited's old Mitsubishi L300 van being taken away to the knackers yard after many years of service.26 June 2014
After getting rid of the old van last month the other one started to give problems. In its case we have swapped it for an imported 4WD Toyota Hiace in which you will see Ela driving to and from sites. So we now have a fleet of white vans all with our logo on the side. If you see us give us a toot.
Esther and I really enjoyed the Hexagon Conference and the time in Las Vegas. I would like to thank Bruce Robinson of Global Survey whose previous trips to the conference made him an excellent guide. There were a number of interesting seminars and displays but we id not succumb and buy anything.
In a couple of weeks we are going up to Whangarei where we will have a stand at this year’s Quarry Conference. This year I hope to be presenting our stockpile app which my developer promises will be ready in time. If you are interested then drop by the stand and have a chat.
Many of you will have noticed that Kamil has been hobbling a bit recently. He injured himself playing squash a while back. Next week he will be getting this seen to and will be away from duties for a little while.
We will be mailing out the next Good News Report soon where you will find a couple of interesting tips to help avoid procrastination. Let me know if you would like to go on the mailing list for this fun newsletter.


Monthly blog of Pilbrow Surveying Limited22 July 2014
Esther and I were up in Whangarei last week for the Quarry Conference. I seemed to be busier than last year in Dunedin. Each year I meet more people so there is a lot of time reconnecting with those I met last year, chats with existing clients and discussions with those showing new interest. I also enjoyed looking around the stands. Even though many of them are not directly related to what we do it is fascinating to see what they do and how they go about putting that forward to prospective customers. I thought that the Data Now concept of data analysis looked interesting and Erik was very enthusiastic about what his systems could do for efficiencies. With next year’s conference being in Hamilton I am going to make more of an effort to attend the functions. I will be able to have someone else on the stand while Esther and I go to the lunches and dinners.
At our stand this year we were showcasing our do-it-yourself stockpile app, the survmatic materials management software and 3D visualizations to help you get your message across for consenting purposes. The cell phone app will enable you to get stockpile volumes just by taking a video of the heap. It uses the same photogrammetry software that we use to process our low level aerial mapping data. Survmatic is a cloud based materials management system which allows you to keep track of your stockpiles. It maintains record of reports, images and quantities in one database. A dashboard view shows current stock and past inventory with a slider to show changes over time. The 3D visualizations take a terrain model and orthophoto collected with our low level aerial mapping system or a proposed pit or rehabilitation design and use that to create a virtual fly through  or manipulation in a free 3D viewer. Send me an email or call me and we can discuss any of these ideas further.
We are short staffed at the moment because Kamil is off for a month recovering from surgery. A year ago he injured his knee playing squash and the surgery was to repair the damage that he had done. He is recovering well, already hobbling around on a crutch, but to make sure it heals completely requires time.

Monthly blog of Pilbrow Surveying Limited23 August 2014
The poor winter weather has given us time to continue investigation of a new UAV system. We are looking to add a vertical landing machine to our fleet to broaden the range of sites that we can use the low level mapping at. We currently have two systems shortlisted one from an Australian developer and the other from a Hamilton company.
In parallel with the UAV research we are also looking at software to handle the resulting point clouds to see if we can improve on our current software.
As the days are getting longer again we will be resuming our South Island work. The low sun angles during winter, especially in the far south, make it difficult to get non-shadowed images. After the equinox we have two sites planned for a client with multiple quarries around the country, with a third in the deep south later in the year.
Kamil should be returning to light duties from next week following the reconstruction surgery on his knee. Initially he will be doing computing work with an occasional site visit.


Monthly blog of Pilbrow Surveying LimitedRodney and Esther Pilbrow during their 25th wedding anniversary celebrations22 September 2014
We had a couple of celebrations over the weekend. Rodney and Esther celebrated their 25th wedding anniversary and Kamil celebrated his 35th birthday. Good times were had by everyone at the respective parties.
Work has continued in the gaps of what seems to have been a very wet and wild September. It will be nice when everything evens out again and we can get some consistency which makes planning for jobs much easier.
With regard to the UAV advancement we have decided to purchase two different systems. The first is expected in a couple of weeks and the other should be in the beginning of November. This will enable us to do a larger variety of sites than currently and also handle the month end surge.
Kamil’s leg is healing up nicely and he is spending more time at work and going out to some sites. He should be fit and well for the summer.
We have taken on a new chainman, Mitchell Hickey. He lives locally and hopes to eventually join the Police but in the interim will be working with us.

Rodney, Kamil and Ela are busy doing practice flights with our training multi-rotor UAV, a Blade QX, in preparation for our new larger multi-rotor UAV, which is due at the end of October. The new machine will enable us to increase the range of sites at which we can carry out low level aerial surveys. With a vertical landing capability we will now be able to do those sites which did not have an appropriate landing place for the X100. Smaller sites will also become viable. Whereas before it was quicker and easier to do the small sites with more traditional methods we can use the new system to quickly pop up and take a few images and then process them on site. To assist with this a new laptop has been bought with 32GB RAM and i7 2.4GHz processor.
Give Rodney a call to discuss using it on your site.

We have been continuing with the training for the new multi-rotor. This is called an X8 due to the rotor configuration which is four sets of top and bottom propellers in an X shape. You can see the size of the machine in this photo of Rodney holding it. After being delayed by contrary spring winds the final calibration has now been done and we will soon be able to take delivery and begin using it in our work.
We have a number of existing clients who are keen to use the new machine on their sites, they already know the benefit of getting a full aerial survey of a site prior to work beginning and we can now do this for the smaller sites which were not practical with the X100.
Fletcher Construction are now getting us to do a survey with the X100 twice a month to keep track of the volumes across their large Expressway work site.
Kamil’s leg is getting better and he is now able to spend time on all but the most rugged of sites. He is continuing with physiotherapy for strengthening the damaged area but it will still be a few months before he is back to his pre-injury capability.
