comment INASAFE using US Census data? or similar QGIS hazard analysis - thresholding?
That is not available for Summit County Ohio, where I am. Using the 2002 FEMA floodplane I got about 10% of the people in the floodplane, but I got the 2009 FEMA floodplane and they are significantly different. Now I have about 2.5% of the people in the floodplane. And this is way too high. Thanks to modern zoning ordances, when I examine the high population blocks in the floodplane, they have little or no houses in them. So I'm a little flustered about how to do anything else than manually count houses in each block and enter them manually - with 2500 blocks, that's not very appealing.

comment INASAFE using US Census data? or similar QGIS hazard analysis - thresholding?
OK, I'm working on it but I haven't gotten any smarter. I have Census data for my county, which is shapefiles for each Census block with fields of HOUSING10 for # of housing units in the block and POP10 for number of inhabitants. Since nothing in the INASAFE keyword descriptions seems to allow specifying a specific field, I have to assume that a raster is needed with pixel values. Since population is allowed a datatype of count, I don't understand how that works. Anyone know more about this? - by this I mean is there a way to use the shapefiles with count for exposure?

Thanks for that pointer - I'm not a developer so I'm not good at Github
