Urban Morphological Blocks of Île-de-FranceÎlots morphologiques urbains d'Île-de-France
Îlots morphologiques urbains d'Île-de-FranceUrban Morphological Blocks of Île-de-France
This dataset provides the IMU layer, characterizing urban blocks ('pâtés de maisons') as well as open-space blocks without buildings, covering the entire Île-de-France region as of 2012. Each geographic IMU entity is composed of one or several parcels delimited by the boundaries of trafficked roads, transport infrastructure, and other physical limits. It is published as part of the regional open-data portal for Île-de-France and is useful for urban planning, land-use analysis, and territorial studies requiring a fine-grained morphological breakdown of urbanized and open spaces across the region.[Situation 2012] La couche IMU caractérise tant les îlots urbains (« pâtés de maisons ») que les îlots d’espaces ouverts sans bâti, pour toute l’Île-de-France. Chaque entité géographique IMU se compose d’une ou plusieurs parcelles délimitées par les emprises de voies routières circulées, d’infras...
