Simple download service (Atom) of the dataset: Point location of water bodies (surface between 1 000 m² and 1 ha) in Corrèze

N_PLAN_EAU_IFN_P_019 The DIREN Limousin has entrusted to the National Forestry Institute (IFN) map inventory of Limousin ponds from orthophotoplans. The photographs date from 1999 for the Corrèze and 2000 for the Up and down and the Creuse. In view of the resolution of the photographs, only ponds of which the area is more than 1 000 m² have been surveyed. Some summary data on this work as well as the comparison with the SCAN25 and the BD CARTHAGE® can be found in the document (http://diren.dev.eservices.fr/donnees/eau/etangs/rendu.asp?page=etangs_presentation) This inventory is only partial since it concerns only the ponds of more than 1 000 m² and which are visible on the photographs (water to the time of shooting). Finally, it should be mentioned that bodies of water bordering two departments have been recorded in each of the departments and for the area concerned on the department (in particular Vassivière) which breaks into 1 body of water in Haute-Vienne of 448 ha and two bodies of water in Creuse 153 Ha and 331 Ha) or Lavaud or Bort les Organs that are counted only for the area included in the region. This consequent work of scanning on infrared boards colors leads to a fairly complete inventory of water bodies of more than 1 000 m² (which corresponds to the reporting threshold) administrative). The reliability of this inventory is very good both in terms of the completeness of the base and of the layout of the contours and therefore of the surfaces estimated. This leads to a very interesting tool for bets that can now compare their administrative basis of declared ponds with this inventory (undeclared ponds, comparison of areas) declared,...). But it is also an interesting basis for characterisation of pelvis heads since we can quickly know the number of ponds and the amount of water they represent in a given territory
