[OSGeo-Discuss] Automatic geocoding of PDF documents

[Bob Basques]

All, 

I did something similar to this a couple of years ago (for fun of all things) where I parsed a Craigslist listing, and used the city location information (I used a Census Placename SHP file I think) to plot a location for each item for sale on a map.  The plan at the time was to mapify Craigslist and be able to do geo-filtered queries.  I gotrlb.sharedgeo.o it to work, but got onto other things and never went back to it. 

I used PERL, and as I recall, it wasn't that long of a script, maybe 50 lines or so.  I can look for the code if there is interest.

I can not find a potentially excelent reference that was done by about 5
years ago by maybe a GSoC student that I think then hired on with
Google, but the basically he wrote a document parser that looked for
location references in the text and then tagged the document with
locations and lat/longs. If I remember correctly it as a gazetteer based
system and it is open source and was online somewhere also.
