SYNOPSIS

   Flags:
       --overwrite
           Allow output files to overwrite existing files

       --verbose
           Verbose module output

       --quiet
           Quiet module output

   Parameters:
       file=string
           Uncompressed GNS file from NGA (with .txt extension)

       vect=string
           Name for output vector map

DESCRIPTION

       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.

NOTES

       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 points map.
