UAV Services


Next to specific UAV System Solutions GerMAP offers aerial mapping services. For primary data acquisition we apply our unmanned and automatically flying fixed wing airplanes, multicopters, or VTOL airplanes. Depending on the application our UAVs are equipped with either cameras or other sensors.

Areas of small extent, i.e. up to a few square-kilometers per project, are in the focus. The flight missions might take place in different heights above ground level (AGL) which are subject to national regulations.

We prepare a flight plan based on the interest-area polygon elaborated together with the client. The flight plan might get adapted prior to flight mission and on-site, if local constraints demand it. GPS-waypoint-navigation and use of other sensors let the autopilot expose aerial images location-based and in an photogrammetric, overlapping manner. They are the basic input for all further spatial image processing tasks.

During flight all relevant flight data get stored on-board and are simultaneously transmitted and stored a 2nd time on the groundstation where they additionally get visualized. The pilot in charge may take over full manual remote control at any given time.



In most European countries commercial UAV-flights are permitted within visual line of sight (VLOS) from pilot to UAV only, i.e. within bare eye visibility. Due to this, GerMAP recommends to operate its fixed wing UAV within a radius of 1 km. Areas of up to 1 km² take with one of our fixed wing UAV less than 30 minutes to fly. Where needed one flies several slightly overlapping flight missions, also called „blocks“, and concatenates all aerial images of all blocks, sometimes several thousand images, into one „super-block“ for homogeneous georeferencing.

GerMAP delivers multiple data processing products such as digital terrain models (DTM), digital surface models (DSM), orthomosaics (= image maps), volumes, profiles, contours, and many more, geospatial data sets. GSD of orthomosaics varies mostly between 3 cm and 10 cm. DSMs often possess a raster spacing of less than 50 cm and thus describe fine-grain surface morphology. Color (RGB) images as well as near-infrared (NIR) images and combinations thereof, i.e. false color near-infrared (CIR) imagery are possible. They find applications in various remote sensing tasks.
