Level 2 Digital Terrain Model (NGI)

DTM produced by the NGI, as a regular grid in the World Geodetic System (WGS) and available for Belgium. There are 2 versions of the file. This is the most accurate version, i.e. level 2. Based on this DTM in the WGS system, a DTM file was created in the Lambert coordinate system. The DTM was drawn up on the basis of the contour lines of the topographic maps on a scale of 1:50,000.
