| description | In this study we evaluated the quality of the DEM acquired by the Shuttle Radar Topography Mission(SRTM) for Italy through comparison with cartographically derived DEMs, available for the Italian territory.Comparison was carried out analyzing differences in elevation and slope angle at regional scale. Thecomparisons carried out at the regional scale disclose a general increase in slope angle values with thechange in resolution and a moderate difference in mean elevation. From these results, we highlighted thatimproved surface-based DEMs, based on advanced SAR, have vertical values that approach or exceedthat of current medium resolution surface products. Moreover, this study helps to provide a benchmarkagainst which future DEM products can be evaluated. |
