This class parses and utilizes a subset of the information from the GEOnet Names Server.
See http://earth-info.nga.mil/gns/html/ for the description of the data and the raw data files.
From the 700 MB of raw source files, a compact 'GCF' file containing only the geographic coordinate and a single name string are extracted for each populated place.
The GCF (75 MB) can be then loaded and used for rough geocoding of international addresses
bool Countries::FindPlaceWithGuess | ( | const char * | country, |
const char * | place, | ||
DPoint2 & | geo, | ||
bool | bUTF8 = false |
||
) |
Find a location given its country and placename. If successful, it returns true and places the coordinate in 'geo'.
country | Country input |
place | Place intput - this is generally a town or city |
geo | If successful, receives the resulting point |
bUTF8 | Important! If your country and place names are UTF8 strings, pass true. Otherwise they are assumed to be ANSI (western europe). |
