Soil Occupation Model — Evolution between 2009 and 2017

**Development of large-scale land use 2009/2017 by municipality on** the metropolis Aix-Marseille Provence Data produced by TTI Production on behalf of the metropolis Aix-Marseille-Provence. Evolution of large-scale vector soil occupations between 2017 and 2009 in 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 evolutions 2009-2017. 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 from 2009 and 2017. The evolution of the 2009 vintage MOS around 2017 was produced by crossing the two respective soil occupations. To download the MOS In CSV, Excel, JSON or GeoJson: in the Export tab. Be careful, downloading the entire MOS can take several minutes. In SHP: in the attachments of the Information tab. Download in SHP from the Export tab is limited to 25,000 records (instead of the 50,000 indicated) due to the complexity of the geographical areas.
