Local DEM of the hinterland of Ravenna

The localDEM for the hinterland of Ravenna was created interpolating ground control points (GCP) manually recorded by the Emilia-Romagna region[1]. In December 2018, the downloaded dataset among the almost 400.000 points still included modern artefacts such as artificial fluvial banks and the highway, streets, and railroads. Therefore, all elevation points not classified as “isolato al suolo” (= recorded on the bare soil) were removed to filter out these modern disturbances. The resulting 160.000 points dataset was then interpolated using the Inverse Distance Weighting method[2] to create a local elevation model at 10 m resolution devoid of modern interferences (LocalDEM from now on).
