ReSource provides, in addition to traditional land surveying services, new methods based on photogrammetry with drone technology. We can accurately deliver high-resolution georeferenced data at a low cost. We have already worked with several companies in Iceland and learn extensively the advantages of our approach.

Drone survey is useful where you need many points over a large area or to survey a difficult location and you’ll get an aerial image at the same time. We can make you save a lot on labour time and we process the data and deliver the desired format to our customers whether it is a simple picture, georeferenced orthophotograph, point cloud or even a 3D model or a video.

Our services include:

  • High accuracy topographical surveys including orthophotograph of the surveyed area
  • Viewpoint photography
  • Area and volume calculations for asphalt, stockpiles and quarries
  • Videos for project planning or inspection over building areas





Land surveying for building and civil engineering projects can be a heavy and time-consuming task using the traditional GPS surveying methods. Our drones will map for you in high-resolution elevation of your site as well as deliver a high-quality aerial picture. We can deliver geo-referenced maps with ground elevation at high accuracy along with the picture in order to help you implement your project. Up to today, we had good results over half a day of surveying up to 90 hectares!

Once we deliver high-quality georeferenced orthophotograph including also the Digital Elevation Model (DEM) it is possible for the Engineers and designers to precisely draw all details with regular CAD software. No need to send a surveyor in the field a second or third time because you are missing some information, all is already in the data we deliver to you. Roads, pipes, trenches, parking lots, buildings, etc, all are part of the model and can be drawn using our georeferenced data.



With a 5-20 min flight, we can give you an accurate measure of the large volume of material that no manual surveyor can provide you. This is a powerful tool for the building industry, road construction, quarries and waste management sector. With further processing, we can also use drone data into regular CAD software to calculate volume and surfaces in between two defined surfaces. It is, therefore, possible to calculate in advance the need for material removal or for an addition of material during building projects or landfills for example.



Accuracy is our main concern when we collect data. The new method we apply is changing how surveying of land is approached. While the traditional method is to take points and interpolate in between, photogrammetry method delivers a high-density point cloud that can be later simplified depending on the need for a survey. Accuracy for X and Y axis is typically 2-3 cm. Altitude accuracy may vary depending on the land type and the flying conditions but we have managed over 50 hectares area to obtained an error max of an altitude of 10 cm between real points and generated point clouds. This is highly accurate comparing to interpolated points used in the traditional method as our points are actually existing surfaces.

Sometimes a video or an aerial picture is far better than a technical drawing. If you need many people to explore a site and you want to avoid them to have to move, you can have a video presenting from the position of a bird the working area. It is also possible to use video shooting and picture at different time over a project period for assessing advancement or possible impact of the work on its environment. Here is an extract of a video made for a tender for hot water pipeline replacement.
