Municipal perimeters encumbered by PT2LH servitudes impacting Calvados

This dataset identifies the communal areas encumbered by PT2LH servitudes that impact Calvados. These sectors are established by aggregating the perimeters of the municipalities concerned. These easements are special clearance zones. Their purpose is to protect the path of radio links between two radio-electric centres operated or controlled by the various administrations of the State, against physical obstacles likely to hinder the spread of waves. They are established pursuant to Articles L54 a L56-1 and R21 a R26 of the Postal and Electronic Communications Code.

The geometry of the regulated perimeter of a PPR is constructed by l' geometric aggregation of polygons representing the zones restricted by the PPR.Source of georeferencing:- cadastral reference PCI (DGFIP) or BD Parcellar (IGN) name, version and news to be specified- Scan25 (IGN): number and year of l' edition to be specified- BD CARTO (IGN) or GeoFLA (IGN) (number and year of l' edition to be specified) for prescribed PPRs — List of prescribed and approved PPRNs on the department based on existing information in the; GASPAR application for monitoring PPR procedures. 01/08/2016: Correction of all perimeters using the geometric basis of the 2015 Parcellar Bd.
