Geothematic open data in Umbria region

Detailed information about geology, hydrogeology and seismic hazard issues for Umbria region are contained in a spatial database available as open data format (shapefile or KMZ) and distributed under the regional open data portal called Open Data Umbria (http://dati.umbria.it) where 297 datasets have been produced by Umbria Region until now and most of them are made by Geological Survey. Geological Survey of Regione Umbria carried out a 20 years program to produce 276 geological maps at 1:10.000 reference scale with an accurate geological model of the regional surface and providing millions of geological data. The key word is the characteristic index of the single geologic unit . Characteristic index , shown in percentage, calculates the ratio between the surface of the geologic units compared to their thickness. Thickness value for each geologic unit is intended to be based on rank level and calculated as weighted average of the thickness for each geologic unit.
