[Qgis-user] offline address geocoding
Hello, I am seeking a GIS app to use for a disaster preparedness group. As such, I need full functionality when the Internet is not available. The weak spot for most GIS apps seems to be gecoding street addresses to coordinates (lat/log, UTM, etc). Many apps seem to wind up referencing the geocoding services of google or yahoo instead of doing the work locally. Provided the correct data files (TIGER, etc), can QGIS be used to geocode street addresses without Internet access?

While I haven't done it - you can set up a geocoder with PostGIS for offline geocoding - http://postgis.refractions.net/docs/Extras.html Not sure if QGIS has a plugin to toss addresses to it though.

David, I'm a volunteer contributor to OpenStreetMap. A few of us are working to import addresses into OSM. (Although not all countries have addresses.) I had not considered addresses useful for disaster preparedness. Can you help me understand how address help?

If you look at Seattle, every address and building should be in OSM. Next we want to extend at least the address mapping to all of King County. I can use what you said to help encourage more people to help out. BTW - We could not do this without QGIS and PostGIS. They are a life saver.

Re: [Qgis-user] offline address geocoding
You bring up a good point... for many people that respond to far-flung disasters, disasters are things that happen to other people. FEMA begs to differ, of course! I can live with interpolation to start, but your plan is definitely the target. I'll hook your info into the CERT team to see if I can scare out some mappers. We've trained nearly 1000 out of our 85,000 residents so far, so I've got a pretty big, motivated pool. Have you hooked up with your local CERT/Red Cross/VOAD type folks? They might be a good pool from which to draw mappers. I just learned that many college GIS courses require that each student work on a project, and something like this might be right in their wheelhouse.
