Managers of geographic and administrative databases are interested in changes. Change detection gives you quick, reliable insight into these changes.

Slagboom & Peeters offers change detection based on semi-automatic comparison of aerial photographs and the AHN (the current elevation map of The Netherlands) , if needed. An algorithm identifies potential changes, after which skilled staff visually check the whole project area. All changes are provided with a classification, a geographical location and, if applicable, an address. By carrying out the comparison semi- automatically, Slagboom & Peeters can offer high-quality change detection at competitive rates.

You can indicate which changes are important to you and we will deliver the changes in the geographic (shp/dgn/dwg/dxf) or administrative (xls/txt/mdb) format of your choice. This ensures seamless integration with your existing work process, both technically and content-wise.
