- Statement
- In order to produce our new multipurpose (GIS, CAD...) contour lines for our internal and external customers, we use our 5m resolution DTM, which is being updated continually by means of checks and modifications using photogrammetry. (This DTM is derived from the most recent 1m resolution DTMs which are supplied by the regions. They are products which are derived from the processing of point clouds from LiDAR campaigns. After reprojecting the regional data in Lambert72 into our own datum, Lambert 2008, the DTMs are interpolated again to a 5m resolution.) The updated DTM is then processed through a low filter in order to generalize the modelling of the relief by deleting superfluous details. On the basis of this DTM, contour lines with a 1m25 contour interval are generated for the entire Belgian territory. Afterwards, these contour lines are generalized by means of selection (deleting the shortest contour lines) and by smoothing.
