TINITALY, modello altimetrico digitale d'Italia a risoluzione 10 metri

The DEM was obtained from heterogeneous vector datasets, mostly consisting in elevation contour lines and elevation points from several sources. The input vector database was carefully cleaned up to obtain a seamless TIN derived by using the DEST algorithm, which enhances the TIN mesh with respect to the standard Delaunay triangulation. The whole TINITALY/01 DEM was converted in grid format (10-m cell size) according to a tiled structure composed of 193 elements. See references for additional details.
