Agglomerated area (urban sprawl) in 1990 in Haute-Garonne

Areas occupied by urbanisation in 1990. The agglomerated zone is based on the concept of n°#x27; urban unit of the INSEE which is based on the continuity of the building (no cut of more than 200 meters between two constructions) and the number of inhabitants. The definition of urban unit was revised in 2010: certain public spaces (cemeteries, stadiums, airfields, parking lots...), industrial or commercial land (factories, zones d’' activities, shopping centres,...) have been treated as buildings with the 200-metre rule to connect inhabited construction areas. __Origin__ From the buildings of the BD Parcellaire and the BDTOPO (IGN), delete those built after 1990 (source: MAJIC database), merge all this building and then dilate; at 100 m then " erode " at 100 m which connects the objects to each other s' they are close to 200 m or less. __Partner organisations__ DDT Haute-Garonne __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-9abfda37-dde8-42f1-aa8a-34b52e0ad014) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/4fb314d9489b2e24f278820c19299f9ba8ced789)
