A seamless digital elevation model (DEM) of the whole Italian territory, originally named TINITALY/01 (also known as the "TINITALY" DEM, in short), was presented in 2007 (Tarquini et al. 2007*). The dataset is about the elevation of the bare ground, and thus it can be called a DTM (Digital Terrain Model). This DEM was obtained starting from separate DEMs of single administrative regions of Italy. The DEM is freely available as a 10 m-cell size grid (in GeoTIFF format), in the UTM WGS 84 zone 32 projection system (see the link download).
In January 2023, a new version of the TINITALY DEM is released, named TINITALY/1.1. In this version several inaccuracies of the former DEM are corrected. Along with the upgraded DEM, a suite of DEM-derived products are now available as WMS, WMTS and WCS services: (i) shaded relief map; (ii) slope map using 2.5σ clipping as technique for image enhancement; (iii) Sky view Factor (SVF) map using 2.5σ clipping as technique for image enhancement; (iv) SVF map using equal area equalization as technique for image enhancement; (v) openness down map using equal area equalization as technique for image enhancement; 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.
