- <h2>DESCRIPTION</h2>
- <em>v.in.geonames</em> imports Geonames.org country
- files (Gazetteer data) into a GRASS vector points map. The country files
- can be downloaded from the
- <a href="http://download.geonames.org/export/dump/">GeoNames Data Dump Server</a>.
- The script generates a vector point map. Only original files can be processed
- (unzip compressed file first). These Geonames files are encoded in UTF-8 which
- is maintained in the GRASS database.
- <h2>NOTES</h2>
- The current DB connection is used to write the database table.
- <p>If importing into a DBF database, the original 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 <em>db.connect</em>.
