Urban Task 2001 — Domaine Urbanisme — Hautes-Pyrénées

This version of the urban task corresponds to a use dedicated to the field of urban planning. The parameters and specifications, taken into account and detailed below, correspond to the needs formulated by the urban planning sector. This layer is not intended to be used to identify the PAU (Part currently to Urbanise). The 2001 urban task was carried out according to the CERTU methodology, taking into account two parameters: expansion (D) and erosion (E). Potential uses: General Studies __Origin__ Made from the themes of the BD-Topo, from the layers: — BATIMENT.TAB, — PISTE_AERODROME.TAB, — TERRAIN_SPORT.TAB, — CIMETIERE.TAB, — AIRE_TRIAGE.TAB The areas of ​​#x27; activities initially taken into account in the generation of the urban stain, n' were finally not taken into account, according to the specifications of the urban planning sector. The implementation of urban tasks is based on the principle of: — the creation of buffer of the value ''Dilatation'' around each object, — of l' assembling these buffers — then apply a reduction of the value ''Erosion''. The initial method of CERTU foresees to apply the following parameters: · Expansion: 50 m · Erosion: 50 m When Dilatation = Erosion then the urban spot tangents objects on the periphery. However, in some uses (identification of n°#x27; habitat dispersed in rural areas), lower erosion (20 m) appears to be more appropriate. These specifications and parameters may not be compatible with d' other uses and may be adapted as required. DATA QUALITY: The field & area of the polygon &, may be useful for filtering the smallest, less significant polygons in some studies. It should be noted that at the departmental limit, there may be side effects due to the failure to take into account the buildings of the neighbouring departments. Production objectives: Know the artificialisation of soils. __Partner organisations__ DDT Hautes-Pyrénées __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-67e77958-fb3d-4b0f-a7f8-d5685634065b) * [basic URL of wms/wfs services on the Internet](http://ogc.geo-ide.developpement-durable.gouv.fr/wxs?map=/opt/data/carto/geoide-catalogue/1.4/org_38072/9aff692b-2663-417e-9755-2ee0f9e48150.internet.map) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/ebe4db1d06c866d03f3fbea291f6f25182968591)
