Keen followers of this website will notice that there was no update at the end of December. During the Christmas period Rodney and Esther were away to spend a week with Sally in Waimate. Kamil and Ela went up north to spend time on the beach. Since returning the work has been continuous. Finally the summer highs have brought settled weather and Rodney has been busy catching up with the backlog of sites to be surveyed in the South Island. There has been an increase in construction work due to the fine weather and this has meant lots of setout and lots of topo work. The X8 has been brought into the fleet and we now have days where the X100 and X8 are being used at separate sites on the same day.
A symposium was held in Masterton on the 16th January with over 230 attendees made up of UAV suppliers, service companies, end-users, research groups, government agencies, and Esther and Rodney. It was a day packed with speakers who discussed all aspects of UAV operations from the effect they will have on the economy, how they should be regulated and insured, how they will affect other air users, what UAV research is going on in NZ, how the government views their use and what the future may hold. It is estimated that there may be $125-160 million/year economic benefit to NZ from the use of UAVs. The speakers mainly concentrated on agricultural uses with UAVs expected to increase productivity. Mapping can identify where problems are and assist in pin point placement of the required solution. Whether it is identifying sick plants and applying fertiliser or dry areas and applying water, this information based production is called precision agriculture. There was even talk of using UAVs to count and muster stock. The CAA Director spoke on the work of the CAA around incorporating Remotely Piloted Aircraft into the New Zealand Aviation System. They will be applying a risk based approach to rule making with the emphasis on protection of people and property including other airspace users. The current rules have been deemed not fit for purpose and there is currently work on creating a new rule to cover RPAS. The project is aimed at ensuring appropriate regulation to ensure public safety, and being flexible enough to accommodate the potential range of RPAS applications and future developments. RPAS covers not only small UAVs such as the ones which we use but also potentially full size cargo planes. The CAA has had a policy of education with regard to RPAS use, they have created a leaflet which outlines the current rules and want this to be included with the sale of any UAV especially the all ones which are being sold in huge numbers. Their were only 4,882 registered aircraft in NZ as at March 2014 yet there is likely to be thousands of small UAVs around the country. Here is the link to the CAA RPAS page: http://www.caa.govt.nz/rpas/. Due to a number of stupid behaviours by some UAV users the CAA are now going to be fining people. Of special interest to me was the talk by the Executive Officer for the NZ Agricultural Aviation Association and the NZ Helicopter Association. All Ag operations and a lot of helicopter ops are below 400ft which is where we operate our UAVs. The speaker discussed what could be done to mitigate the risks such as radio communication, NOTAMs, other notifications. A website has been created where RPAS operators can lodge flight plans, it has a map showing where the controlled airspace around major airports and the 4km limit around aerodromes is and gives contact details. Until every UAV and Ag plane is fitted with some form of detect and avoid system, only constant alertness on the part of pilots will prevent an incident. People from a number of different universities around NZ gave a brief overview on work being done with regard to RPAS. Areas being looked at include increased autonomy with units being able to map and direct themselves through an unknown area (Optimal trajectory tracking), sense and avoid systems, automatic landing systems where the UAV looks forMonthly blog of Pilbrow Surveying LimitWind turbines on hills above the Manawatu Gorge spotted while Rodney and Esther Pilbrow were on the way tot eh RPAS symposium held in Masterton on January 16th, 2015.
Inivitation to attend the celebration of the completion of the Taupo Hospital which featured an aerial photo captured by Pilbrow Surveying Limited using their Delta X8 multi-rotor.23 February 2015
Yet another busy month with 11 X100 flights and the X8 used on 6 sites as well as numerous ground topos and setouts. The new airshare site allows RPAS flights to be booked and provides contact details for aerodromes and links the flight request to the various air traffic controls around the country. One such request for permission to fly at a site in Taupo which was within the 4 km zone from the Taupo Hospital heliport led to us capturing some aerial images of their new buildings. One of the resulting photos was used on the invitation sent out by the Lakes District Health Board, as shown to the left.
We are currently working at capacity and not taking on new clients. For this reason we are looking for a new surveyor and chainman so if you know of anyone who would like to work with our little company then get them to give Rodney a call on 0274 979717.

We have been putting the X8 multirotor to good use this month. We averaged a site a day for over a week as we get into sites that have not been viable with the X100. Mainly stockpile surveys but this picture shows Rodney and Esther Pilbrow using the X8 multirotor to survey the Te Henga Wetlands for the Ministry of Primary Industries. Thanks to Wayne Grant of AsureQuality who took this picture of us in operation.

A new page outlining the operation of the X8 and a Fact Sheet for the X8 have been added to the website and can be viewed here:

We have completed our South Island quarry work during this month. It has been difficult trying to schedule in these last two sites between the patchy Autumn weather and our increasing X8 work closer to home.
The last two sites were Blackhead Quarry in Dunedin and Dunback Quarry inland from Palmerston. At the end of the mapping flights we captured aerial shots across the quarries enabling us to create the two awesome panoramic images shown below.
The workload for the UAV fleet shows no sign of decreasing as more and more people become aware of the cost effectiveness of our systems and the stunning outputs that can be achieved.

Earlier this month Altus used our Delta X8 power unit with their gimbal base to do some filming for NZ Trade and Enterprise at the Field Days in Hamilton. Altus are the only company with permission from the CAA to film over people due to the triple redundancy safety systems of the Delta X8.  There were many unmanned aerial systems on display but only the X8 has dual autopilot, dual GPS, redundancy in motors and a ballistic parachute system. The accompanying photo shows the X8 over the displays.
With the upcoming changes to the Part 101 rules we have decided to purchase another multirotor system from Altus. This will be a Long Range version of the X8. Our current X8 is being put to use in sites that are completely impractical for a fixed wing UAS and the LR version will replace the X100 for a lot of our other sites where the landing areas can be difficult if the wind is not from the right direction.
At the end of June we have a large number of sites carrying out year end stock take surveys. We will be cramming as many as we can into the few days either side of the month end.
Ela and Kamil will be away on leave during the latter part of July, off to somewhere warm for a couple of weeks.

Monthly blog of Pilbrow Surveying LimitedLast week I was invited by Dave Allen to give a talk to the surveying class at UNITEC in Auckland on the use of RPAS in the Construction Industry. Mike Long of Altus came up to do the piloting of the demonstration flight of the Delta X8. My talk explained the reasons why I chose to use unmanned aircraft systems for our construction surveying business, how they operate, what the legal restrictions are and how I then present information to my clients. The students will have questions relating to this in their examination later in the year. The accompanying photo is a drone selfie of the group.Pilbrow Surveying / Altus Delta X8 filming over Field Days June 2015 for NZTE25 July 2015
Last week we again had a stand at the NZ Institute of Quarrying’s Annual Conference. This year we had a number of panorama images which had been prepared using images captured by our X8 multi-rotor at the completion of the mapping flights. These were printed out onto the PVC material used for the large format site plans which we do for people. The reaction to these panoramas was how stunning they were. The accompanying photo shows Esther posed in front of the stand.


As the conference was held in Hamilton this year Rodney decided to do a talk titled “RPAS Use in a Quarry Environment”. This outlined how we use our remotely piloted aerial systems in the quarries. The talk gave a brief run down on surveying methods, then explained why we chose to go with a remotely piloted aerial system. It described how we get 3D data from 2D images, followed by an overview of RPAS capabilities and limitations and what accuracies can be achieved. Current legal restrictions to using these systems was covered and lastly some examples of what we do with the resulting data were shown. At the formal dinner at the end of the conference Rodney was awarded the Lyn Jordan Memorial Award for the best technical paper given at an Institute Group Meeting. We hope to upload a version of the presentation to you tube for those who are interested but missed the talk.

Monthly blog of Pilbrow Surveying LimitedRodney attended the launch of the CAA’s new Part 102 rules relating to UAV operation in NZ. This photo shows the minister Simon Bridges about to have a fly of one. The emphasis was how the new rule and changes to Part 101 will enhance safety around uav use while allowing for flexibility in applying the rules as technology changes. The coverage of the event by TV One and 3 did well to get out the message that everyone is covered by these rules not just commercial operators. During the talks by the various officials mention was made of the increasing number of uses for uavs but as usual it seems that only uav use for filming and fancy photography is sexy enough to get mentioned. More mundane uses such as surveying even though they give massive productivity gains don't capture much attention.

Following the trip to Intergeo in Stuttgart we are working our way toward acquiring a LiDAR system for our UAV. With such a system we will be able to rapidly survey the ground underlying vegetated areas which are not able to be captured using photogrammetric methods. At present to get such areas a laborious ground survey using total stations has to be done in under the canopy of the trees. It will be a number of months before the new system is ready to go. We will be doing a lot of work in testing to ensure that we provide our clients with meaningful data.

We have had a fairly busy time this month with 16 missions carried out by the X8 and LRX. Two of these were to carry out stockpile volume surveys and an update of the pit and clean fill area at Higgins Aggregates Meremere (formerly Baldwin’s Quarry). Following the work the Manager Kerry Reilly (pictured to the right) had this to say:
Hi Rodney,
Many thanks for the great surveying  job you completed at the Higgins Meremere Quarry last week, I must say I am impressed with the latest addition to your fleet of aircraft, the helicopter was incredible to watch and the results were second to none even though it was operating in windy conditions.
Where will all this technology lead to,  quite mind boggling , the obvious benefits being the time and labour saving which enabled you to have the numbers on the table so quickly and accurately at an affordable price. The innovation of supplying a quality  large scale photographic record that is  printed on PVC material is new to me,  the quality was outstanding and I am sure will prove to be very durable in our environment, thanks again .

The sharp eyed among you will notice that there was no update for December. This was due to a heavy workload not allowing the time to do one. We are very busy with a large number of clients ringing in the first couple of weeks of the new year with new projects that they are starting. We have even brought the X100 out of its hibernation and used it for the update of the Hampton Downs Landfill for Envirowaste.
The images below are from the project on which Rodney was working during the Christmas period for Downer. This is the Le Strade di Capra site for Kiwirail. It involved the realignment of 450m of rail and installing some new turn outs and the associated services.
The LiDAR for the UAV progresses with the final components decided upon and being bought. Assembly of the unit will be followed by testing.

This year has been going amazingly quickly, it is the end of February already. This year we are celebrating the 20th anniversary of the incorporation of Pilbrow Surveying Limited. To honour this milestone you will see we have added a special seal to our usual logo. I want to acknowledge that without loyal customers, suppliers and friends we would have nothing to celebrate. Thank you for your support.

It is fitting that it is this year we will be moving into LiDAR, keeping up our history of technological advancement in construction surveying. The LiDAR for the UAV has moved to the next stage, which is waiting for delivery of components. Once they arrive things should progress more quickly and we can get some testing underway. We will keep you up to date on developments.

Following months of work to prepare our exposition Pilbrow Surveying Limited has been issued a Part 102 Unmanned Aircraft Operator Certificate by the Civil Aviation Authority. To obtain such certification applicants must submit an 'exposition' showing that they have identified hazards and risks of their operation, and ways they will mitigate those risks. There are places where consent to operate is only forthcoming for Part 102 certificated operators.  Having our UAOC will allow us to work in these areas. 
We are also updating the X8 to the new Altus Delta LR44. Utilizing the ALTUS UAS patented "stagger-prop" technology the LR44 combines a significant increase in flight time over the Delta X8 while maintaining the same true high wind stability it is known for.

We have been exceedingly busy over the past few months and have been unable to update the current news. Even though the weather has been bad our workload is heavier than ever before. More and more people have been seeing the benefits of the high resolution up to date aerial images in their  projects. To the extent that now we get asked to fly sites that previously we would not have deemed it worth while. The clients have decided that the value of these orthophotos outweighs the extra cost. 
During May / June we carried out a survey for the Hobsonville Land Company of their Hobsonville development. It was only because we now have our Part 102 certification that we were able use our UAVs for the mapping of this site. David Ison, the Precinct Director / Manager—Planning and Infrastructure, HLC had this to say:
Hobsonville Land Company is very pleased with the UAV aerial survey and imagery work undertaken by Pilbrow Surveying. Rodney Pilbrow was easy to deal with and very knowledgeable in this area of work. The ability to produce the required outputs quickly and at a relatively low cost is a huge advantage over conventional survey methods. The high quality survey and imagery will be invaluable in our planning and development work at Hobsonville Point.

We again had a stand at the NZ Institute of Quarrying Conference. This year the Quarry Conference was held in Blenheim. We were one of nearly 60 exhibitors so there was a lot for the delegates to look at. This year we decided not to take down one of our drones or the new sonar boat but rather we had the Virtual Reality headset, the HTC Vive, as our drawcard. Using photogrammetry data captured during a stockpile survey, people could take a virtual tour of a small quarry in the South Waikato. With the headset on you feel as if you are right there in the quarry. We only had a small area to move around in but virtual teleport points placed around the site enabled people to explore the entire 3 Ha site. Being completely immersed within the virtual environment, standing on the edge of the highwall gave the same “oh wow” feeling as if you were there for real. The ultimate aim is that clients will be able to take a virtual walk around their pits and see how proposed design benching, landscaping and new plant will look before committing to the real thing. We will also be looking at Augmented Reality as a way for Quarry Operators and others to be able to view their proposed works out on site.

We have also purchased a small remotely controlled sonar boat. This system collects data using a sonar pod mounted underneath with our GPS to collect the positional data. This will be used to obtain levels of the base of dams, lakes, tailings ponds and streams. Such a survey would usually require a survey team to be out on the water and all the inherent risk and H&S requirements which would go with that. The sonar boat enables us to capture a denser number of points than before without being exposed to the water hazard.

Here are some more great testimonials from clients:
With the purchase of an additional processing plant for our Tamahere sand quarry we were in need of specialised expertise in aerial mapping and measuring. The project brief outlined was to map and profile the processing plant at the existing quarry site and then transfer that information to the new site to assist the engineers who were tasked with the massive project of undertaking the physical move. 
We found that Rodney instantly  grasped the parameters of our project and worked with both our management team and our engineers to get us the required information in an easy to understand format and then with little warning was able to be on site to mark out the exact areas required for the new plant location. Not only did Rodney make our job a lot easier but went above and beyond to assist our team to get the job done right first time.  
With the use of Rodney’s state of the art drone and 3D mapping system our job of positioning the plant with pin point accuracy was a breeze. This assisted us greatly in getting the shift completed on time. 
Rodney worked within our comprehensive health and safety regulations at both sites and at all times acted in a responsible and professional manner. 
We strongly recommend Rodney and his team to any one in our industry. 
Brad Pierce, CEO,  Waikato Aggregates

We here at Inframax Construction have been using Pilbrow Surveying to do our monthly stockpile volume surveys since May 2013. Initially only one site was being surveyed using the drone but since Rodney acquired the multi rotor drone early in 2015 we have been getting aerial images for all of our Quarries as part of the stock up dates. I have found the high resolution images a great help for planning. We now have quarry plans with contours prepared for all of our pits so that we can work out our stripping requirements. Rodney has also helped out with pit designs so we can quantify the availability of rock. Being able to present the data in a variety of useful formats has helped when presenting to others in the company. I am looking forward to trying out his latest thing, visiting a virtual quarry. I would recommend Pilbrow Surveying limited to anyone who wants to get professionally presented up to date information for their quarries.
