DESCRIPTION¶
v.in.geonames imports Geonames.org country files (Gazetteer data) into a
GRASS vector points map. The country files can be downloaded from the GeoNames
Data Dump Server. 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.
NOTES¶
The current DB connection is used to write the database table.
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. 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
http://www.geonames.org/export/codes.html, char(1)
feature code : see
http://www.geonames.org/export/codes.html, 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)
