DESCRIPTION imports country files (Gazetteer data) into a GRASS vector points map. The country files can be downloaded from the GeoNames Data Dump Server. 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.

NOTES calls to import data into GRASS.

The current DB connection is used to write the database table (see db.connect). 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 db.connect (eg. to SQLite driver).

The main 'geoname' table has the following fields

geonameid         : integer id of record in geonames database
name              : name of geographical point (utf8) varchar(200)
asciiname         : name of geographical point in plain ascii characters, varchar(200)
alternatenames    : alternatenames, comma separated varchar(4000)
latitude          : latitude in decimal degrees (wgs84)
longitude         : longitude in decimal degrees (wgs84)
feature class     : see, char(1)
feature code      : see, varchar(10)
country code      : ISO-3166 2-letter country code, 2 characters
cc2               : alternate country codes, comma separated, ISO-3166 2-letter country code, 60 characters
admin1 code       : fipscode (subject to change to iso code), isocode for the us and ch, see file admin1Codes.txt for display names of this code; varchar(20)
admin2 code       : code for the second administrative division, a county in the US, see file admin2Codes.txt; varchar(80) 
admin3 code       : code for third level administrative division, varchar(20)
admin4 code       : code for fourth level administrative division, varchar(20)
population        : integer 
elevation         : in meters, integer
gtopo30           : average elevation of 30'x30' (ca 900mx900m) area in meters, integer
timezone          : the timezone id (see file
modification date : date of last modification in yyyy-MM-dd format
