The face of the Drone industry is changing. Girl power is taking an increasingly important role in the Drone industry. And not before time.

It has long been proven that women have skill sets in engineering, training and project management that more than complement their male counterparts.

Enter Drone Girl. A new breed and welcome force in the rapidly changing fashions of the Drone industry.

As a male driven hobby, given the focussed engineering that goes into the build of a drone or UAV, it’s not surprising that men were historically at the forefront of the game. But as the Drone Industry has flourished its not surprising that girls have decided it is their frontier too.

At QuestUAV we have a team of 20 people, almost a third of whom are women. Two of our staff are truly “Drone Girls” and fulfil roles on the flight team itself.

Kerstin Traut is our Geoinfomatics and Remote Sensing Specialist and UAV Operator. She is often complemented on the fact that a mission runs smoother when she is on the team, it is better organised and more productive. And more fun! She has carried out missions in Germany, UK, Philippines, Thailand, Cyprus and Indonesia.

Carla Taylor who comes from our Sales Team has recently carried out her Flight Commander training and joined our flight team on a recent demo in the USA. She found that being a woman on the flight team created positive dynamics, particularly on the States. Of course an English Accent helped.

Jo Harris and Heather Ainsworth are on QuestUAV’s Marketing Team and keep up to date on daily drone news. Jo comes from a Multirotor background and has a thirst for drone technology and enjoys reading up on new developments, which she applies to the formation and editing of QuestUAV’s news articles. Heather has spent quite a bit of time with both our social media followers externally and our research, development and production teams internally – as a result she is one of our more fluent members of staff when it comes to our drone technical specifications.

Throughout the drone industry more women are getting involved, SheFlies in Australia are becoming a big hit and even launching demo and training days in Australia and New Zealand. QuestUAV are followed by many female pilots around the world and they are finding out first hand that our product is designed to be easy-to-use – something the male pilots have been keeping to themselves when showing off their mission prowess.

Already the QuestUAV product is being flown by several female clients who have attended training at our UK based flight school. A fixed wing drone package is a leading solution in the Mining, Surveying and Agricultural sectors. For those who look to benefit from the survey outputs without the expense of managing their own flight teams, QuestUAV offer Industrial Services as well as sales of the product.

A QuestUAV Case Study from Kazakhstan


Mine operators know that safety precautions are of utmost importance in the daily routine at a mining site. Conventional surveying methods involved considerable effort and resources on the ground.

Starting with electronic tachometers and later with ground GPS, surveyors have had to enter high-risk areas on the ground and spend considerable time to finish a survey. Some of the most acidic areas cannot even be entered as the risk to health and safety is too high. When compared with conventional ground surveying, it has been proven that the use of drones or Unmanned Aerial Vehicles (UAVs) for surveying immensely reduces the exposure to risk for surface workers involved on site.


Aerial Survey with QuestUAV 200 Surveyor drone (left) vs. ground survey with a total station (right).

Instead of walking a mining site with ground equipment, areas of whatever risks involved are surveyed by flying over the site. UAV surveys can be done in a fraction of the time of a ground survey and generally provide higher accuracies. Surveying projects that usually take weeks with conventional surveying methods can now be completed in just a few hours. Hence, UAV technology minimizes risks while reducing costs and boosting productivity.


This autumn TEAMQuest was called by KAZ Minerals to help raise safety and efficiency to a higher level than ever before at one of the biggest open-pit mines in eastern Kazakhstan. Two local teams (8 people) went through an extensive two weeks training program on professional flight operations and aerial open-pit surveying with a QuestUAV 200 Surveyor. Following training by QuestUAV, both teams now fly the two Q-200 Surveyors on a daily basis with the following objectives:

View of the mining site (leach pad)


  • To monitor mine status
  • To monitor & plan pit and leach pad progress
  • To map & plan infrastructure (roads, buildings)
  • To monitor the perimeter security fence
  • To estimate stock pile volumes
  • To monitor & plan site rehabilitation

KAZ Minerals is focused on copper mining, producing both copper cathode from oxide ore and copper in concentrate. The pit development started in early 2013 supported by extensive surveys on the ground. It is predicted that the mine will become the biggest mining operation in Kazakhstan within the next three years. A crucial part of KAZ Minerals strategy for a safe and efficient pit development is to replace conventional survey methods with latest UAV technology. KAZ Minerals decided to go with QuestUAV as we provide a robust and stable system for difficult environments, high quality sensors and ongoing support for the flight operations.



Since September 2016 KAZ Minerals have surveyed their mining sites and expansion areas on a daily basis with two QuestUAV 200 Surveyors. The QuestUAV Surveyor carries a Sony A6000 camera with a 16mm wide-angle lens providing image data down to 2.9cm GSD at 400ft. The images are the basis for 3D models, topographic site maps, infrastructure maps, pit volume estimations as well as maps for security and surveillance. Geospatial accuracy (cm-level) is achieved by combining image data with a combination of permanent and temporal Ground Control Points (GCPs) distributed over the mining site.

Bungee launch of the QuestUAV 200 Surveyor

Generally, the Q-200 Surveyor has been designed to complete high-quality aerial surveys in the quickest way possible in any environments ranging from desert and tropic to glacial and Arctic/Antarctic. The automatic camera trigger and the gimballed camera system allow to take pin sharp pictures even at high wind speeds of up to 55 km/h.

The Q-200 Surveyor is launched with a bungee launch line and is either landed via parachute or belly landing. The latest version of the Q-200 Surveyor comes with a Post-Processing-Kinematic (PPK) option, which provides high mapping accuracies down to 3cm without the need of physical ground control points.



Daily flight missions have become an essential part of the KAZ Minerals site planning and mine development. The work of the flight team forms the basis for all further work in developing the mineral resources - distributing information to engineers, planners and geologists. Aerial measurements are used to develop and display the plans, maps and profiles required for mining and exploration. Three of the major applications are explained in the following sections.



The basic application of the survey results is to provide a general overview of the status of the mine. Orthomosaic, Digital Surface Model (DSM) and 3D point clouds are used to keep the KAZ Minerals management up to date about recent developments in the open-pit and the leach pad. The figure below shows sections of the orthomosaic illustrating the level of detail gained from QuestUAV data.


Sections of the orthomosaic of the open pit.


Orthomosaic and DSM are the basis for an in-depth topographic analysis of the development of the mining site. Valuable information can be extracted from orthomosaic and DSM, such as infrastructure maps (roads, buildings), water bodies, contour lines, the flow of water, risk maps etc. These datasets in combination with expert knowledge of mining personnel are used for the development of intelligent management plans for the development of the mine.

UAV based measurements are the fastest and easiest way to measure stockpile volumes. Photogrammetric software, such as Pix4Dmapper or Agisoft Photoscan allows to automatically calculate volumes on the basis of aerial imagery. KAZ Minerals has proven that UAV based measurements are not only faster, geodetic accuracies are even higher when measurements are taken from a UAV.

volume calculations

Volume calculations are performed on the basis of the Digital Surface Model (DSM). The difference between the base elevation of a pile (green) and the pile elevation (red) is the Cut Volume – when the terrain is higher than the base. Fill volume is the volume between the base and the terrain when the terrain is lower than the base. The Total Volume is the sum of Cut Volume and Fill Volume.



KAZ Minerals stated that the QuestUAV system greatly improved the surveying work at the mining site in terms of:

  • Improved worker safety
  • Higher efficiency
  • Increased site development productivity
  • Higher accuracies of the geodetic work

Nowadays UAV surveys are the basis for all further work related to developing the KAZ Minerals mining site, including engineers, planners and geologists.

QuestUAV Drones – Reliable and Accurate Tools for Coastal Monitoring

QuestUAV Drones - Reliable and Accurate Tools for Coastal Monitoring

A Case Study on Long-Term Erosion Mapping in Northeast England

The Urgency to Measure Coastal Erosion

Protecting coasts from erosion is a global mission.In the UK alone, the British Geological Survey states that across England and Wales 113 000 residential properties, 9000 commercial properties and 5000 hectares of agricultural land are within areas potentially at risk of coastal erosion.

Mitigating the effects of climate change requires coastal protection studies and coastal protection measures. As every planner knows, though, this increases the burden of allocating ever-reducing financial resources.

Accurate studies of the changes, gleaned from historical studies, combined with best practice from current studies and environmental factors allow the most effective and efficient decisions to be taken in coastal protection anywhere in the world.

Sea Erosion

Drones or Unmanned Aerial Vehicles (UAVs) are a great asset for monitoring the stability of a coastline and for carrying out a rapid initial survey after a storm event.

UAVs can quickly survey potentially difficult and dangerous large sites with a very high level of detail.

Erosion monitoring, assessing cliff stability, monitoring coastal vegetation and changes in land volume or coastline state are only a few examples of the applications of UAVs in coastal areas.

QuestUAV’s Special Relation to Coastal Applications

QuestUAV has always had a special interest in using drones for coastal applications. Our company is located in a port town in North-East England on the shore of the North Sea.

The conditions in which our UAVs have to perform are challenging, but have greatly helped create one of the most stable fixed-wing UAV platform on the market.

High Spatial Accuracy and Gimballed Sensors

QuestUAV airframe design and sensor gimbals ensure data quality even in turbulent conditions with wind speeds up to 65 km/h.

Latest PPK (Post Processing Kinematic) technology on board QuestUAV drones allows survey mapping of an area down to 2cm spatial accuracy without the need of Ground Control Points (GCPs).

GCPs are normally not easy to place along the cliffs and dunes of a coastline, so the use of our PPK technology makes surveying quicker and less expensive.

Coastal Erosion Comparison 3

Our UAVs have been used for a variety of coastal surveys across the world, such as:

  • Rapid pre- and post-storm assessment to quantify forecasted storm impacts
  • Large industry environmental monitoring: nuclear power stations / mining sites
  • Coastal property monitoring (insurance)
  • Monitoring coastal sand digging activities (cement)
  • Habitat monitoring / sea colour surveys
  • Breakwater inspections
  • Geological cliff and rock surveys / baseline surveys

QuestUAV is keeping an eye on the local coast

The Northumberland coastline is designated as an Area of Outstanding Natural Beauty (AONB) and conservation area due to its significant landscape and wildlife values.

QuestUAV started monitoring the local coast of Northumberland between Alnmouth and Cresswell back in 2008.

Since 2008 the local coast has been hit by two exceptionally strong flood events - one in November 2013 and one recently on the 13th of January 2017.

Immediately after the latest storm a QuestUAV crew flew the local coast, assessing the impact of the floods on the basis of the long-term image series. Our workflow involves a correlation of information from historic sources, satellite imagery and 3d-modelling.

Coastal View

We concentrated our survey on the less protected dune land, especially to see how much property owners have lost from erosion.

Our crew flew the site with a Q-200 PPK drone which has the great advantage of surveying an area with centimetre-level accuracy without the need for GCPs. The UAV provides images with a spatial resolution of 2.9cm at 400ft.

Coastal Erosion Comparison

Time-Series to Detect Storm Impacts

The figure below shows a picture of a dune property before (September 2016) and after the latest flood (January 2017). (Note that we show only a representative section of a much larger survey area).

The time series shows that the latest flood changed the frontline of the dunes by 1 – 2 metres. Rocks and previous coastal erosion measures became exposed. Large volumes of sand and grass were removed and slumps occurred within hours of high tides.

Coastal Erosion Comparison 2

Coastline development 2013-2017 at the Low Hauxley coast: QuestUAV image time series.

Our calculations show that approximately 850 tonnes of dune and dunefoot was lost along an 80 metre stretch of coastline and the high water mark receded by up to 2.2 metres at the most critical point. The expected slumps that will happen as a result of erosion at the toe are expected to carry a further 300 tonne loss within 12 months.

Coastal Erosion Example

Coastal Erosion at Low Hauxley coast.

To see the long-term development of the coastline we also included a flight from January 2013 in our analysis.

The good news is that the coastline recovers over time!

The storm event in November 2013 had comparable impact as the latest flood. Fortunately, sand, stones and organic matter deposits along existing structures and the coastline recovers over the years.

As long as the big storms do not increase in frequency, we do not see the local coast particularly endangered by coastal erosion. We will stay alert though.


Climate change can cause unpredictable events and it is more important than ever to keep an eye on the development of the coastline.

Drones will continue to take an ever increasing role in the monitoring and assessment of coastal erosion and assist in effective decision making for local planners and environmental bodies.

QuestUAV endeavours to build drones which are able to fly in harsh and difficult environments. The conditions we have to test our UAVs in help us create the most stable fixed-wing UAV platform on the market.

Our drones are flown across the world and clients count on the stability of the system, especially in difficult conditions as it is often the case in coastal regions.

We also provide the workflows that allow accurate mapping and timely interpretation of processed results.

Datahawk with Gas Sensor on Show (L) and BGS Stand (R)


BGS had with them a Datahawk aircraft to show at the exhibition – this is a similar craft to what they use to carry out their monitoring surveys. Visitors to the event could see and feel the drone and discuss the technical applications and capability of the UAV gas monitoring system.  Questions asked were how accurate is the GPS on the UAV? 

“Is the modelling of methane done in real time? ”

“Does the drone carry a camera as well as the sensor? ”

“Could it also measure for carbon dioxide or hydrogen? ”

“How long can it fly for? ”

Interested exhibition attendees took a flyer which explained the project progress, rationale and the advantages of the new system versus current gas monitoring systems together with the system capabilities. It is expected that data from the UAV gas monitoring system will help to demonstrate that either there are no fugitive gas emissions or help to pinpoint and quantify gases in the atmosphere.

BGS continue to use Quests Q200 Surveyor drone for mapping and surveys.  They have recently placed another order for a second unit with thermal capability to use in the field.

AgNav Showcasing the QuestUAV DATAhawk at NAAA Conference


AgNav attended the NAAA Conference in Long Beach, California at the end of 2016, in part, to launch its new line of Unmanned Aerial Vehicles (UAVs) outfitted with various kinds of sensors. At this conference, they showed off the UAV line, including the QuestUAV DATAhawk, the QuestUAV Surveyor Pro and the Agri Pro V2-1 – which form the main part of the market in North America and beyond.

Visitors at the conference were thrilled to see a Drone on display and the QuestUAV DATAhawk was shown prominently at the booth.

Agnav Show

Q-100 DATAhawk on Show

"The drone itself actually captured more floor traffic, so it is definitely an asset to our product line." - AgNav


Applications that users wanted to perform with the UAV included both photo imagery and NDVI imagery for crop health. There was also the usual question about price. In terms of price, the system was billed as a mid-range solution but unique because of the different payloads that can be carried and the quality of the system. The very convenient means of launch and the system's sleek profile were other highlights indicated by visitors as being of interest.


Visitors were given a brochure that identified how users can make money through various kinds of services such as the following:

  1. Crop Security: Some crops are particularly valuable and people will steal them. A UAV solution may prove ideal for flying without detection and warning the authorities as to the presence of unwanted visitors.
  2. Agriculture: The NDVI indicator is a valuable component for users seeking to make additional money from their planes. A UAV solution may prove ideal for this purpose - not particularly expensive and costs can be rcovered from the first year of operations.
  3. "Insurers: Insurers are responsible for providing coveage in the event of spray mishaps, such as spraying over houses or on pets or livestock. A photo of the affected site will allow the insurer to honour claims made by individual farmers or persons affected by spray fly-overs.



This was essentially the first or initial launch of AgNav's UAV offering in conjunction with QuestUAV. The QuestUAV DATAhawk on display at the conference attracted as many as 30 individuals, with a sale being prepared as a result.

Interest in NDVI was also particularly high compared to standard imagery, with users less sure how photos can be used to make money as a service offering in place of NDVI.

Survey Drone Sensor Gimbal Inforgraphic


QuestUAV Sensor Gimbals Improve Flight Efficiency By More Than 15 Percent


Demands on fixed wing drones are growing continually. Other than copter drones, fixed wing platforms are generally used to cover large areas (hundreds of hectares) in a short amount of time. Standards on flight endurance and efficient area coverage are growing throughout different industries such as surveying, agriculture, mining or surveillance. To create a high-quality 3D model of a survey area sensor performance and image overlap is essential. Sensor and drone platform have to compensate for the effects of wind and turbulences causing blurred images and low image overlap. From day one QuestUAV has been developing gimballed systems and fine tuning platform stability in order to gain maximum quality and performance from a flight mission. The following sections outline the importance of image quality and overlap and show how a gimballed system can increase efficiency by more than 15 percent


QuestUAV Gimballed Drones


Image overlap is crucial...

When mapping an area with a drone or Unmanned Aerial Vehicle (UAV), the UAV will have to fly and photograph the survey area in a grid-like pattern ensuring that every feature on the ground (e.g. a tree or a building) is “seen” in multiple photographs. For the generation of 3D models, these photographs have to have sufficient overlap in flight direction and between grid lines (side overlap). Photogrammetry software providers like Pix4D or Agisoft Photoscan generally recommend an overlap of 75% frontal and 60% side overlap.

Flight Image Overlap Diagram

Sensor choice and gimbal influence data quality...

Besides image overlap, GSD (Ground Sampling Distance) is crucial for modelling an object in high detail. Hence, a good sensor and a UAV system which enables a stable flight and continuous overlap are essential for the generation of high-quality maps and 3D models, especially in windy and turbulent conditions. Image sharpness and overlap can significantly deteriorate when the UAV is pushed around in moving air. Therefore, a sensor gimbal might become crucial for data quality, spatial accuracies and hence for mission success. Various QuestUAV missions have proven that a gimballed system compensates for effects like blurred or oblique images and lack of overlap.

Stereo Photogrammetry Diagram

Stereo-photogrammetry to extract 3D positions...

Once a feature is photographed from different angles stereo-photogrammetry can be applied after a flight during the post-processing phase. Common points are identified in each image and a line of sight (or ray) can be constructed from the camera location to the point on the object. The intersection of these rays determines the three-dimensional location of the point and in combination a 3D model of the surveyed area.



The sensor is the heart of a UAV and depending on which sensor is flown it will determine what data a UAV is capable of collecting. Ground Sampling Distance (GSD), image sharpness and noise level are all dependent on the sensor chosen for a flight mission. As an example, the QuestUAV 200 Surveyor carries a Sony A6000 camera which captures very high detail with a 24.3 effective megapixel APS-C sensor allowing to acquire data down to 2.9cm GSD at 400ft. The Exmor APS HD CMOS sensor ensures an extremely fast performance, sharp image quality and low noise images, even in low-light conditions.


The major advantage of a gimbal is simply to allow the sensor to continuously point directly towards the ground (nadir view), while the aircraft itself is manoeuvring around in yaw, pitch and roll. Especially in high winds, a compensation for the movement is essential to keep the image overlap required for photogrammetry processing. If there is no gimbal the general solution is to increase side overlap. However, increasing the side overlap causes the aircraft to fly more grid lines and turns and hence reduces area coverage and flight efficiency. Overlap recommendations by photogrammetry software providers are generally around 75-80 percent frontal and 60-65 percent side overlap.


QuestUAV Gimbals can reduce the image overlap to 40% and still guarantee the data quality.

Various studies with a QuestUAV 200 Surveyor and QuestUAV 100 DATAhawk have proven that a gimballed system allows reducing the image overlap from 65 to 40 percent and still guaranteeing enough overlap for photogrammetric processing and data quality even in high winds. By reducing the amount of grid lines and aircraft turns the already impressive ground coverage of a QuestUAV system is further increased. As shown in the figure below the amount of grid lines is reduced from 13 to 10 and the total path length from 10.1 km to 8.3km - a decrease of 18 percent!


Image Overlap Comparison

When compared to an orthomsaic based on 65 percent overlap the 40 percent overlap orthomosaic is equally good in terms of image matches and data quality. The number of overlapping images was in both cases continuously higher than five for each pixel of the orthomosaic resulting in an excellent 3D model of the surveyed area.


Orthomosaic Overlap Comparison


QuestUAV has proven that a sensor gimbal significantly improves the already outstanding ground coverage of a QuestUAV drone. The QuestUAV sensor gimbal compensates for the effects of wind and turbulences causing blurred images and low image overlap. By using a gimbal an area can be flown with only 40 percent side overlap without a reduction in data quality. Hence, mission efficiency is increased by more than 15 percent.
