                         Elevation Model (DEM) validation is often carried out by comparing 
                         the data with a set of ground control points. However, the quality 
                         of a DEM can also be considered in terms of shape realism. Beyond 
                         visual analysis, it can be verified that physical and statistical 
                         properties of the terrestrial relief are fulfilled. This approach 
                         is applied to an extract of Topodata, a DEM obtained by resampling 
                         the SRTM DEM over the Brazilian territory with a geostatistical 
                         approach. Several statistical indicators are computed, and they 
                         show that the quality of Topodata in terms of shape rendering is 
                         improved with regards to SRTM.",
