What happens to the data collected during an aerial survey? How can it be analysed and how is it displayed? We have produced a short film to show you – please take a few minutes to watch:
We fly our aerial surveys using the ‘eBee’ which is a nimble and accurate craft and carries a high resolution camera (16Mp) which can capture a photo every 3-4 seconds. Individual flight times last up to a maximum of 45 minutes.
Our pilots are qualified to strict standards set by the UK Civil Aviation Authority (CAA). In June 2013 KaarbonTech became the first company in the UK with qualified pilots and an approved operating system.
Back on the ground the data and imagery captured is modelled to meet our client’s requirements. Here is an example of data that has been modelled to analyse cliff and coastal erosion:
Coastal Erosion Sidmouth Devon
Development Manager, Leigh Harris has been surveying coastal erosion at Sidmouth in Devon.
The survey was the latest phase of a Beach Management Plan for Sidmouth which is being undertaken by CH2M Hill Halcrow consultants and East Devon District Council.
The use of aerial surveying using unmanned aerial vehicles, known as UAVs or Drones, is anticipated to grow strongly within the the UK quarrying, aggregates and waste management sectors.
Quality Of Survey Data
Technology Company KaarbonTech have completed their first aerial survey of a UK waste management site.
A recent example is company KaarbonTech who were commissioned by APR Services, on behalf of a client, to conduct an aerial survey verifying the volume of waste at a landfill site in Kent. Accuracy was essential as the data was destined for submission to the Environment Agency.
KaarbonTech pilots are fully qualified and operate within flight guidelines approved by the UK Civil Aviation Authority. The survey process is quick and non-disruptive to the function of the site.
Pilots establish a mobile hub from which to remotely pilot the SenseFly eBee aircraft. High accuracy GPS is used to plot key reference points across the survey site. The team then fly the aircraft in a precise grid pattern to cover all of the designated area. The aircraft carries a high resolution camera (16Mp) which captures a photo every 3-4 seconds.
“We compared the accuracy of the data set provided by KaarbonTech and were pleased that the results were comparable with traditional methods of surveying. The speed of the service allowed us to provide a quicker solution for the site owner with the added benefit of high resolution aerial imagery.”Andy Bradford, Survey Director for APR Services, who commissioned the survey
“The adaptability and accuracy of aerial surveying using unmanned aerial vehicles is proving of commercial interest to the aggregates, quarrying and waste management sectors.”Mark Entwistle, Managing Director of KaarbonTech
Traditional ground based methods of surveying remain of value but are likely to be increasingly complemented if not replaced by maturing aerial technology.
KaarbonTech Ground Breakers
KaarbonTech was the first company in the UK to fly the eBee SenseFly Unmanned Aerial Vehicle in 2013.
The aircraft carries a 16MP camera allowing it to shoot aerial imagery at 3cm pixel resolution over areas up to 12sq KM.
The eBee can fly in winds of up to 45km/h (12m/s) which is ideal for surveying in British weather. The aircraft has a flight time of up to 45 minutes and is highly portable, fitting into a small carrying case, and is easily launched making it an ideal solution for clients.
Our CAA qualified pilots have used the aircraft to survey sites as varied as dams, quarries, coastline and the London Olympic Park.
Along with other worldwide users KaarbonTech Managing Director, Mark Entwistle, has written a testimonial which you can read here:

Flying high to promote Anglesey
The clear aerial pictures were commissioned to promote the investment opportunities available to businesses in Anglesey.
The island of Anglesey is famous for Holyhead which is the second busiest ferry port in the UK and handles over 70% of all road vehicles passing through Welsh ports.
This is another example of the innovative range of uses of unmanned aerial vehicles and the way in which they can promote business investment.

UAV SURVEYING AT SWANAGE
A typical output achievable from 45 minutes of flying time. Used for coastal erosion measurement, there are may other sectors adopting the use of UAV. For more information visit www.kaarbontech.co.uk or call 0800 804 8844
UAV’S REPLACING COSTLY OR DANGEROUS WORK
A recent report by the UK’s Aerospace, Aviation and Defence Knowledge Transfer Network (KTN) found that applications for unmanned aircraft are said to be worth some £260bn – replacing costly or dangerous work done by manned planes, or opening up new applications that are currently out of reach.
Crop or wildlife stock monitoring, search and rescue, and check-ups on railway lines are some of the envisioned uses of UAs.
UK to bring in drone registration
The UK government has announced plans to introduce drone registration and safety awareness courses for owners of the small unmanned aircraft.
It will affect anyone who owns a drone which weighs more than 250 grams (8oz).
There is no time frame or firm plans as to how the new rules will be enforced and the Department of Transport admitted that “the nuts and bolts still have to be ironed out”.
The drone safety awareness test will involve potential flyers having to “prove that they understand UK safety, security and privacy regulations”, it said.
The plans also include the extension of geo-fencing, in which no-fly zones are programmed into drones using GPS co-ordinates, around areas such as prisons and airports.

Using UAV for Quarry Surveys
We manage UAV surveys for a variety of applications. Quarry UAV surveying is one of the safest forms of capturing data in the dangerous quarry environment. It ticks the box for health and safety requirements and is quick and relatively easy to perform.
One of our customers has requested another survey at the end of the groundwork season, of a quarry that we regularly survey during the year. He took the time to share some feedback with us:
“We had a ‘Technical Excellence’ Away Day yesterday at the ExCel centre in London. One of the topics of discussion was the efficiency of UAV surveys (and other drone applications for engineering) which we appear to underutilise. I have since forwarded on my review of the UAV surveys (KaarbonTech produces (absolutely top-notch, in my opinion and plus the price is reasonable!)”.
