Dataset Direct Download Service (WFS): Urban envelope of the built in 2016 on Les Deux-Sèvres (from the Topo comic book)

This built urban envelope can also be described as an “urban task”. It is defined as the area delimiting a set of parcels constructed on a given date. This envelope is only a spatial reference for locating a boundary of construction according to different design criteria. It is in no way the currently urbanised part defined under the application of soil law, which is much more restricted. The latter is determined on the basis of factual elements of the ground and in the light of jurisprudential criteria. Nor is it possible to measure the areas consumed by urbanisation because it is based on always questionable modeling. This envelope, however, reveals interesting spatial distribution features over time. These differences can be attributed to the land structure of agricultural areas (cultural typology, parcel geometry, cultural methods of setting up farms, etc.), to land-based urbanisation patterns depending on the territory or, on the contrary, to more intensified forms of this residential development (e.g. regulatory aspect of urban planning documents). This envelope was made from the following layers of the 2016 NG Topo BD: — BATI_INDIFFERENCIE, — BATI_INDUSTRIEL, — BATI_REMARKABLE, — CIMETIERE, — CONSTRUCTION_LEGERE, — PISTE_AERODROME, — RESERVOIR, — TERRAIN_SPORT
