Soil Occupation Model 2009

Large-scale soil occupancy 2009 by municipality on the metropolis Aix-Marseille Provence Data produced by TTI Production on behalf of the metropolis Aix-Marseille-Provence. Large-scale vector soil occupancy of 2009 on the territory of the Aix-Marseille Provence metropolis cut by municipality. Nomenclature of 96 posts on 4 levels compatible with the nomenclature CRIGE PACA. Projection: Lambert 93 (compliant with the EMR). Attention: The cutting of the polygons at the strict perimeter of the municipalities has generated UMC and LMC which no longer comply with the nomenclature. The accuracy of the databases produced allows optimal use between 1/5 000th and 1/10 000th. The reliability rate after external quality control and in the order of 95 %. Polygonal vector layer, topological of the 2009 vintage. UMC from 500 to 1 000 m² in the urban area. UMC from 1000 to 2 500 m² in agriculture. UMC from 500 (water) to 2 500 m² in natural areas. The production methodology is a computer-assisted photo-interpretation (PIAO) on Ortho-photo natural color and Infra-Red 2009 of 0.15 and 0.20 m resolution respectively. Exogenous data were used to improve the quality of the product, including the IGN scan25, BD-Topo. Photo-interpretation scale between 1/1500 and 1/3500.
