Soil Occupancy Model – Evolution between 2009 and 2017

Evolution of large-scale land use 2009/2017 by municipality on metropolis Aix-Marseille Provence

Data produced by TTI Production on behalf of the metropolis Aix-Marseille-Provence.

Evolution of large-scale vector land occupations between 2017 and 2009 in the territory of the Aix-Marseille Provence metropolis divided by municipality. Nomenclature of 96 posts on 4 levels compatible with the CRIGE PACA nomenclature. Projection: Lambert 93 (compliant with the EGR).

Attention: the cutting of polygons at the strict perimeter of municipalities has generated UMCs and LMCs that no longer comply with the nomenclature.

The accuracy of the databases produced allows optimal use between the 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 urban areas. UMC from 1000 to 2 500 m² in the farm. UMC from 500 (water) to 2 500 m² in natural spaces. The production methodology is computer-assisted photo-interpretation (PIAO) on Ortho-photo natural color and Infra-Rouge from 2009 and 2017.

The evolution of MOS from 2009 to 2017 was produced by crossing the two respective soil occupations.

To download the MOS

In CSV, Excel, JSON or GeoJson: in the Export tab. Please note that downloading the entire MOS can take several minutes.

In SHP: in the attachments of the Information tab. SHP download from the Export tab is limited to 25000 records (instead of the 50000 shown) due to the complexity of the geographic areas.
