Converting a NIMA text file into geojson
From Wildsong
For the Mapping Vietnam project
First download place names from NIMA: ftp://ftp.nga.mil/pub2/gns_data/vm.zip
Unzip the file, which gives us "vm.txt" containing tab delimited data. The file has over 51,000 entries, just what I need! A big data pile!
Field names are on line 1, and they are described here: http://earth-info.nga.mil/gns/html/gis_countryfiles.html
