Our UAV is able to cover terrain through a programmed route in order to make movement-free high-resolution photos, which can be further processed by GIS applications.

Firstly, the area that has to be examined, will be looked at in detail, and based upon this; the most ideal flight plan will be designed with the help of GPS – coordinates and waypoints. Once on the terrain, the UAV flies autonomously along the programmed route and waypoints.

During this process, images are being made that overlap vertically. The UAVs Geobox synchronizes these automatically with the UAV’s GPS. This information is saved in the photo’s EXIF – file.

For projects which require a greater degree of precision, a number of GCPs (ground control points) can be measured with a GPS/GNSS receiver. These measured coordinates serve as reference points and are later on added to the software.

Back on the ground, the data is downloaded and can be processed either by the client or by us.

The photo that is obtained this way is called an orthophoto: a scaled, geometrically corrected aerial photo. The photo does not show any signs of distortion, just like an adapted map projection. Unlike a photo that has not been corrected, an orthophoto can be used to perform measurements because it provides a correct image of the surface of the Earth. The photo is adapted to the topographic relief and corrects the distortion of the lens and the tilt-and-roll camera movements.




When the orthophoto is ready, various photogrammetric applications can be started.

Photogrammetry as a method can be extremely widely used. A lot of disciplines deal with measurements in images. Apart from final products, such as maps and geo-information, there is a lot of differentiation in photogrammetric products: the (digital) aerial photos themselves or processed digital orthophotos or orthomosaics.

  • A digital elevation model (DEM) is a digital image of the surface (of the Earth) or of the ground by means of surface topography. Sometimes, a difference is being made between a digital terrain model (DTM) that reflects the ground level and a digital surface model which reflects the height of all objects on the surface of the Earth, included trees and buildings. The terms DEM, DTM and DSM are frequently confused with one another or defined differently. A DEM can be displayed as a grid (a matrix of squares) or as a TIN, (a network of irregular triangles. DEMs are often used in geographical information systems and are the most frequently used base for digitally processed relief maps.
  • A digital terrain model (DTM) reflects the recorded area in 3D. Through the use of color and shadows, a good image of the different structures in the soil can be obtained. In a DTM, it is also possible to construct different layers of the recorded area. Beneath these layers lies a raster (within the professional field it is defined as a grid). Subsequently, the layers can be compared with one another. These different layers can also be used in other software programs, and as a result, different kinds of maps can be made.
