More New Orleans Flood Maps

More flood maps of New Orleans (see this morning’s entry). Kathryn Cramer, whose blog has turned into an immense resource for Hurricane Katrina information, links to a Google Maps hack that shows the approximate water depth in flooded areas; because of the limitations of Google Maps, it’s a bit of a kludge, in that you click on a point and get a textual response rather than something more, well, cartographic, but it’s useful nonetheless. She also points to Flood Level Maps, which models which areas are flooded and which aren’t — it doesn’t indicate depth, but it’s somewhat easier to parse than satellite and aerial imagery that can be ambiguous in many instances.
