Map of areas subject to hydrogeological constraint

The information layer represents the areas subject to hydrogeological constraints referred to in Articles 1 and 7 of Royal Decree 3267/1923. The result comes from the mosaic of the information available in the SITs of the provinces. For the province of Pavia, the IGM maps were digitised at scale 1:25,000 made available by the State Forestry Corps, Provincial Command of Pavia. The reconnaissance character of the information and the scale limit (from 1:25,000 to 1:10.000 for some provinces) make the information layer useful for spatial planning. Different uses, including administrative management of constrained areas, necessarily require local-scale verification also using cadastral data.
