Hi Robert

> With recent flooding in the eastern US, I am wondering if anyone is doing this?  If so:
> * Are you mapping risk or incidence or both?
> * Are you using raster or vector to calculate flood risk/incidence?
> * If vector, what types of shapes, TIN or other?
> * What delivery method are you using, i.e., desktop analysis only, web-mapping, mapserver, etc.

Although we (the InaSAFE project - http://inasafe <http://inasafe/>.org) don’t do flood mapping, we do provide tools to do analysis on flood layers (as well as other hazards) and produce potential impact reports. Currently our impact reporting is for to roads, buildings and population, though we have future plans to include support for damage and loss assessments, land use impacts (e.g. how many hectares of cropland were inundated) and so on.

InaSAFE is free & open source software and runs as a plugin in QGIS (just search for InaSAFE in the plugin manager). We are also in the ‘thinking’ stages of building a near-realtime tool for flooding on our http://realtime.inasafe.org <http://realtime.inasafe.org/> platform.

We would be very interested in hearing about good online sources for flood data that we can some how make accessible to users of InaSAFE.
