Detailed Description

This class parses and utilizes a subset of the information from the GEOnet Names Server.

See http://earth-info.nga.mil/gns/html/ for the description of the data and the raw data files.

From the 700 MB of raw source files, a compact 'GCF' file containing only the geographic coordinate and a single name string are extracted for each populated place.

The GCF (75 MB) can be then loaded and used for rough geocoding of international addresses
