Urban Spot 2018 – Department 17
Description
**Summary**
The urban task is an automated modeling of the grip of the built urban fabric.
It was carried out according to the methodology proposed by CEREMA. The urban spot is achieved through the creation of a 50 m buffer zone around the built elements of the BDTopo. The elements thus obtained were subsequently merged and then underwent a 50 m erosion in order to obtain the envelope of the built elements.
**Projection system**
Lambert 93 (2154)
**Genealogy**
The urban task 2018 was carried out on the basis of the elements: Building, CIMETIERE, TRANSPORT EQUIPMENT (except for values: crossroads, other equipment, ports, rest or service area) PIST_AERODROME, RESERVOIR, TERRAIN_SPORT, POST_TRANSFORMATION, BDTOPO 2022.
Indeed, the various elements of the BATI theme of this version of the TOPO comic correspond to an update phase as of 19 April 2018.
The different layers were merged to undergo the following treatments:
1- a buffer zone of 50 m,
2- fusion of buffer zones,
3- a buffer zone of -50 m,
4- break-up of geometries,
5- cutting of the layer obtained by common.
