SYNOPSISv.in.gns v.in.gns help v.in.gns file=string [vect=string] [--overwrite] [--verbose] [--quiet] 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
DESCRIPTIONv.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.
NOTESThe 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.
