Similar to Free sources of mapping data for France, does any one know a source for free downloadable flood and precipitation maps for Belgium?
The flood maps for the north of Belgium
In addition to the above post, I'd like to point out there's several datasets. The one referered above holds the THEORETICAL floodable areas, which is used as far as determining the requirements for waterbuffers goes, there is however a dataset known as 'recent overstroomde gebieden': http://www.agiv.be/gis/nieuws/?artid=1510
it lists all areas known to have flooded since 1988. Upon registry through the GIRAF application (the sales bit of AGIV) this data can be requested for free, in both SHP and GML formats.
