Land cover Region South 2019 1/3

Regional Land Occupancy Database - OCSOL BD 2019 - on the Provence-Alpes-Côte d'Azur region. This version was made as part of the update contract carried out by the Provence-Alpes-Côte d'Azur Region. Produced from SPOT 6 satellite images (6m) and completed by a PIAO (BD Ortho) work. It is based on a 3-level nomenclature of the CRIGE PACA on 47 posts (derived from Corine Land Cover). Its scale of use is between the 1/50 000th and 1/25 000th. This database was produced with the aim of providing regional actors with a tool for analysing and observing major trends in land use trends at the sub-regional level. It is a polygonal vector layer, topological, with a global Minimum Collection Unit (MCU) of 5000 m2 with the exception of greenhouses, PAPAM and wetlands which are at 3000 m2. The production methodology combines PIAO for the skeleton and part of the urban and SPOT satellite image classification for agricultural and natural classes. Many exogenous data have been used to improve product quality, including the IGN TOPO® DB and Scan 25®, the DGPI cadastre, the Parcellaire Graphique Register (RPG), IGN/IFN forest mapping and local databases (MOS).
