Large scale vector maps, orthophotos and other ancillary geographic information are crucial in the maintenance of a railroad network. The temporary association EUROSENSE-WALPHOT therefore has been awarded by Infrabel-Tuc Rail, the Belgian railway infrastructure managers, with a large project regarding the provision of actual and detailed geo-information on the 3500 km long Belgian railroad network.
The project, executed over a period of three years (2009-2011), consists of flights with vertical and oblique cameras on the entire network, and the subsequent processing towards accurate digital orthophotos and 3D large scale vector maps.
On the 24th of March 2011, EUROSENSE-WALPHOT finished the flights over the entire railroad network and has assured, once again, an in-time execution of the data acquisition. In total, almost 40.000 vertical images with a ground resolution of 5cm and 80.000 oblique images have been acquired.
