v.in.gns imports US-NGA GEOnet Names Server (GNS) country
files (Gazetteer data) into a GRASS vector points map. The country files
can be downloaded from the NGA GNS Web Server (see below). The script
generates a vector point map. Only original files can be processed
(unzip compressed file first). These GNS files are encoded in UTF-8 which
is maintained in the GRASS database.
The current DB connection is used to write the database table.
Generally, column names longer that 10 characters are shortened to
10 characters to meet the DBF column name restrictions. If this is a
problem consider choosing another database driver with db.connect.
To filter outliers (points outside of a country), the v.select
module can be used to perform point-in-polygon tests. v.select
saves only the GNS points falling into a country polygon into the new
GEOnet Names Server files for countries and territories
