Dataset description
This lot sheet refers the data produced in the framework of the OSCOM project by the 3 DRAAFs of the former Aquitaine, Limousin and Poitou-Charentes regions, now merged into DRAAF Nouvelle-Aquitaine (NA).

Communal land use (OSCOM) is the product of a spatial analysis tool (L’Observatoire des Sols at the communal scale), allowing to generate, at the level of a department, an aggregate communal layer of land use, according to an algorithm for the successive integration of a set of geographical layers derived in particular from the BD-TOPO® and the BD-FORET® of the IGN, the Graphical Parcellar Register (RPG) of the MAAF and the ASP and the Majic base of the DGFiP.

Originally developed as part of a collaborative work involving, under the aegis of an interservice GIS CoPil, the services of DRAAF and DREAL of Haute-Normandie and DDTM of Eure (27) and Seine-Maritime (76), this tool is now widely shared between State departments and beyond, and can be adapted according to local specificities.

Its objective is to estimate land cover and its evolution according to a pragmatic approach based on a purely computer processing of heterogeneous layers of vintage and precision, which implies taking precautions when using the results obtained.
The nomenclature used to characterise land cover from all these layers is based on the 14 posts in level 2 of the Corine Land Cover 2006 nomenclature, i.e.:
00-Mixed spaces,
11-Planned areas,
12-Industrial or commercial areas and communication networks,
13-Mines, landfills and construction sites,
14-Non-agricultural artificialised green spaces,
15-Unbuilt spaces awaiting requalification,
20-Mixed agricultural land,
21-Arable earths,
22-Permanent sections,
23-Prairies,
24-Other agricultural land,
31-Forests,
32-Bests with shrub and/or herbaceous vegetation,
51-Mainland waters.

For the 2013 version
All data used are dated from 2013 except BD_FORET (Version 1 for 24 and 47 — version 2 for the 33, 40, 64 of 2012)
This is the unvalued raw data. Qualification tests are underway in some territories
Aggregate layers are being developed. The aggregation concerns the simplification of the land cover layer of raw data.

To date:
— the 2013 OSCOM vintage is produced on the following departments: 24, 33, 40, 47, 64, 16, 17, 79, 86.
— the 2014 OSCOM vintage is produced on department 87, 19 (part)
The missing departments from this list will soon be posted online.
For the departments of Limousin (19, 23, 87), the production of the 2009 vintage is under way.

WMS and WFS addresses:
Warnings
— Please delete any spaces that might appear when copying/pasting the address into the GIS software
— Problems with displaying multi polygons via the use of WFS (under resolution) — prefer data download if presence of multi polygons
— WFS display of more than 500 objects via the WFS impossible at the moment
