Digital surface model

The digital surface model (DSM) 1m is a homogeneous and regular grid of points indicating the height of the earth's surface in order to model the landscape.

The product "DSM1meter", abbreviated DSM 1m, gives every 1m in X and Y the height of the earth's surface, i.e. the ground or any other permanent and visible element of the landscape (vegetation, construction, ...) in relation to the Belgian zero level (fictitious zero D of Uccle). It is therefore the orthometric height, commonly called: altitude.

Statement

The 1m DSM is obtained by interpolation in Lambert 2008 of the raw height data regrouping the source data, in Lambert 72 and at 1m resolution, of the Flemish and Walloon regions.

The source data used for the production of this DSM are the DSM at 1m resolution of the regions: those of the AIV (ex-AGIV), for the Flemish region and those of the SPW, for the Walloon region.

These source data are collected and processed to obtain a homogeneous and regular grid with a point every 1m in X and Y indicating the height of the land surface.

The two regional organisations providing their product in Lambert 72, the IGN reprojected the data into Lambert 2008 and carried out an interpolation in order to obtain a product with round coordinates and then assembled them so that the DSM 1m product thus created covers the entire Belgian territory.
