[HOT] Re : : New Bing Imagery in Mali and delimitation of riverbanks

[Pierre Béland]

Hi Stephane,

In your wiki page,  you suggest the incorporation of natural hazard data either in OSM or in a fork project of OSM. Your definitions are interesting and lets hope that some discussions will eventually emerge from all of that.

Am I the only one here who thinks that we should rather try to promote a model that allows for inclusion of other natural hazards?

Even in areas with huge fluctuations of the water levels, people are clever enough to build infrastructure where there is *in general* no water. flood_prone=yes (or any similar tag) should be reserved for extents bigger than waterway=riverbank (and where, usually, you will find fields, houses... that might be affected by the high waters).
