Unmanned aerial vehicles (UAVs) for aerial photography (APS) are revolutionizing industries such as land management, cadastral surveys and construction by saving time and money compared to traditional methods of obtaining APS data. UAVs allow GIS specialists to receive, process and provide geodetic data in a timely, accurate and safe manner.

The technology is based on obtaining high-precision coordinates using GNSS systems (Global Navigation Satellite Systems). Satellite signals (GPS, GLONASS) are received during flight. The signals are recorded simultaneously on two receivers: the base receiver, installed on the ground at a point with known coordinates, and the on-board receiver installed on the UAV.

After the flight, data from the base and on-board receivers is copied into the program, the joint processing of which allows for centimeter (geodetic) accuracy in determining the coordinates of the centers of the photographic projection for subsequent photogrammetric processing.

KazUAV solutions for aerial photography using unmanned aerial vehicles and for data processing allow generating an extended list of data, such as:

Orthophotomap: a single file or mosaic with a hierarchy of scales

Digital surface model - includes buildings and vegetation, processed DTM (DTM) - digital terrain model; formats - geotiff or kmz

Digital topographic plans: vectorization of all ground objects with a scale of up to 1:500 and a relief section of up to 0.5 meters

3D model: textured georeferenced terrain model, formats - OBJ, 3DS, VRML, DXF

NDVI index map: a single file or mosaic with a hierarchy of scales and much more

Data obtained using UAVs can be instantly used to take measurements, calculate volumes, identify defects, damage and imported into any format for use in geoinformation systems. Our UAVs collect data even in high-mountain areas and in adverse weather conditions.
