ENS (Sensitive Natural Spaces) - Department of Calvados

The perimeters of the natural sites form the synthesis of the intervention sites of the Conservatoire du littoral, the pre-emption zones of the departmental council, as well as the parcels acquired outside the intervention sites and pre-emption zones. **Collection context** The Department's Department of Natural Environments establishes the perimeter of natural sites from the vector layer of the intervention sites of the Conservatoire du littoral and the pre-emption zones of the Departmental Council of Calvados. It also takes into account the parcels already acquired outside the intervention sites and pre-emption zones, from the cadastral matrix. **Collection method** The vector data are then integrated into the geographical information system - GIS - of the department of Calvados.
