TopoRec – Map Viewer for smartphone & tablet

Discover old traces from above: aerial photo analysis with orthophotos in TopoRec

With TopoRec, you can view, compare and evaluate high-resolution orthophotos on your smartphone or tablet – for historical analysis, terrain interpretation or simply for curiosity.

In combination with other map layers, your surroundings become an archive of past use and developments.

What are orthophotos – and why are they so valuable?

Orthophotos are rectified aerial images in which distortions caused by camera tilt or differences in terrain have been removed. They combine the accuracy of a map with the richness of detail of an aerial photograph.

They are an indispensable tool for historical landscape analysis: you can recognize old field structures, ditches, traces of paths or the remains of foundations – things that have long since disappeared from today’s maps.

Analyze aerial images & orthophotos – mobile with TopoRec

TopoRec provides you with a selection of high-quality orthophotos – directly in the app, without additional data acquisition. You can compare different years, combine them with LIDAR and shaded maps and mark your own observations directly on the map.

Especially in combination with terrain models and historical maps, a complete picture of the landscape is created – for archaeologists, researchers, teachers, treasure hunters or simply anyone interested.
