I had the idea some time back of working on an app that would take a GEDCOM and identify the geo-coordinates of each person's birthplace, then map these on a Google map. Do you know of any app that does this already. My last go at it showed that the hard part might be mapping places as expressed in my GEDCOM to standardized place names. I think maybe Library of Congress's GeoNames API could do this with human intercession.

Just thought I'd see if this has been done.
