TINITALY, a digital elevation model of Italy with a 10 meters cell size, version 1.1

The dataset is a 10 m-resolution DEM in grid format covering the whole Italian territory. The DEM is obtained by interpolating the original DEM in Triangular Irregular Network (TIN) format. The TIN version benefited from the systematic application of the DEST algorithm. The projection is UTM, the World Geodetic System 1984 (WGS 84). To provide the dataset as a single seamless DEM, the sole zone 32 N was selected, although about half of Italy belongs to zone 33 N. The database is arranged in 193 square tiles having approximately 50 km side. In addition to the DEM (TINItaly_DEM), the OGC links supply the following DEM-derived products: (i) shaded relief map (TINItaly_Hillshade); (ii) slope map (TINItaly_Slope); (iii) Sky view Factor (SVF) map using 2.5σ clipping as technique for image enhancement (TINItaly_SVF_2d5); (iv) SVF map using equal area equalization as technique for image enhancement (TINItaly_SVF_EA); (v) openness down map using equal area equalization as technique for image enhancement (TINItaly_OD); and (vi) Hue-Saturation-Value (HSV) composition image with slope (2.5σ clipping) as saturation and SVF (2.5σ clipping) as value, according to RRIM (Red Relief Image Maps) style maps (TINItaly_HSV); (vii) slope map using 2.5σ clipping as technique for image enhancement (TINItaly_Slope_2d5).
