Short Description

The Graphical Parcel Register (Registre parcellaire graphique (RPG) is a geographical database allowing the identification of agricultural parcels. Its primary purpose is to provide a spatial reference for aid applications under the Common Agricultural Policy (CAP). The anonymised version of RPG with information on the main crop on the agricultural parcel (before 2015, on farmer’s block) is publicly available. RGP is managed by the Service and Payment Agency (ASP) . In 2015, RPG version 1.0 was replaced by RPG version 2.0. Even if the two products both describe agricultural parcels on the French territory, their content is quite different. In version 1.0, the information is provided at the level of a farmer’s block, in 2.0, at the level of a parcel. Farmer’s blocks remain present in the RPG 2.0 data, but only as a separate shapefile with blocks’ ids and geometries. Limitations - the RPG data must be handled with caution:

• not all of the agricultural land is included (e.g. agricultural land for which the aid application has not been submitted),
• gaps mentioned above are not the same every year (e.g. general rules related to aids have changed),
• agricultural parcel (or in the data before 2015, farmer’s block) could be modified by the operator even though there was no change in the field.

Coordinate Reference System

EPSG:2154 (RGF93 / Lambert-93 - France) , more info. Use the GDAL command below to convert the GSAA collection's CRS into CRS of your choice:

ogr2ogr [-s_srs srs_def] [-t_srs srs_def] [dstfile] [srcfile]

• s_srs <srs_def>: set source spatial reference
• t_srs <srs_def>: set target spatial reference
• <dstfile>: file with destination projection definition
• <srcfile>: file with source projection definition

Example of converting from EPSG:2154 to EPSG:3857

ogr2ogr -s_srs EPSG:2154 -t_srs EPSG:3857 gsaa_3857.shp gsaa_2154.shp
