+# TINITALY: High-Resolution Digital Elevation Model of Italy
+
+TINITALY is a high-resolution Digital Elevation Model (DEM) covering the entire Italian territory with a native grid resolution of 10 meters. Developed by the Istituto Nazionale di Geofisica e Vulcanologia (INGV), the DEM is derived from a Triangular Irregular Network (TIN) constructed using heterogeneous elevation data sources, including regional  topographic maps, GPS points, and radar altimetry data. The TIN structure is enhanced using the DEST algorithm, which improves input data by evaluating inferred break-lines,  resulting in a seamless and accurate representation of Italy's terrain. TINITALY is particularly valuable for applications in geomorphology, geology, environmental studies, and  hazard assessment. Additional information can be [found here](https://tinitaly.pi.ingv.it/)
