If geospatial data for cetain areas of expertise are visible in stereo aerial imagery or orthophotos and can be photogrammetrically measured, GTA GeoService GmbH can capture these data for you.


Measurable data are:

  • Areas
    e.g. green areas, street areas, playgrounds, parks, woods, cemeteries, water areas, etc.
  • Locations
    e.g. of trees, street lamps, traffic lights, pylons, manhole covers, etc.
  • Linear objects
    e.g. railway tracks, road centerlines, power lines, etc.


The thematic geographic data can be combined with the geographic basis data.
