Map visualisation service (WMS) of the dataset: [DRAAF NORMANDIE] Municipal-scale Soil Observatory — Calvados Department — Millesime 2010

The Observatoire des Sols à l’Echelle Communale (also called “OS communale” or “Oscom”) is a geomatic tool developed within the framework of a partnership work involving the DRAAF of the former Haute-Normandie region (on the initiative of the project), the DDTM of Seine-Maritime, the DDTM of Eure and the DREAL of the former Haute-Normandie region under the aegis of a DRAAF/DREAL/DDTMs interservice SIG Copil. It consists of generating vintage graphic layers according to a successive integration algorithm of a set of reference graphic layers, of the same vintage (except the forest layer and the Majic parcel layer, which date from 2000 and 2009), notably from BD-TOPO® and BD-FORET® from IGN©, the agricultural RPG of the ASP and the Majic parcel of the DGFiP. The objective is therefore to be able to estimate the land cover and its evolution at the municipal or supra-communal scale according to a pragmatic approach based on a purely computerised processing of the compilation of heterogeneous layers, in particular in terms of precision, which implies taking precautions regarding the use of the results obtained. The nomenclature selected for this project is based on level 2 of the Corine Land Cover nomenclature. It consists of 5 level 1 posts (0-mixed spaces, 1-Artificial territories, 2-Agricultural territories, 3-Forests and semi-natural environments, 5-Water surfaces) and 14 level 2 posts (00-mixed areas, 11-urbanised areas, 12-Industrial or commercial areas and communication networks, 13-Mines, landfills and construction sites, 14-Non-agricultural artificialised green areas, 15-Unbuilt spaces awaiting requalification, 20-mixed agricultural lands, 21-Arable lands, 22-Permanent plants, 23-Prairies, 24-Other agricultural land, 31-Forests, 32-Milieux with shrub and/or herbaceous vegetation, 51-continental water).
