GeoID Dictionaries

GeoID Dictionaries

The Microsoft .NET Passport Software Development Kit (SDK) is released with several dictionary text files. These files are loaded into the Passport LookupTable object to facilitate GeoID-related conversions. For example, you can use the Passport LookupTable object loaded with the regions.dat file to look up the names of regions throughout the world or a particular region's matching GeoID code.

File	Description of fields
city.dat	Index into city.dat
Country.dat	GeoID, friendly name of country, index into RegionLabel.dat, index into PostalLabel.dat, ISO country code
lcids.dat	LCID, text by which that language is identified
PostalLabel.dat	PostalCode index, type of postal code distinction
region.dat	Country, (region index; region name)
regionlabel.dat	Region index, type of region distinction
TimezonesLocs.dat	Index, time zone distinctions
TimezoneNames.dat	Index, time zone distinctions
Timezones.dat	Region index, time zone distinctions
us_region_to_zip.dat	Index, (ZIP prefix; ZIP prefix)

All of the default dictionary files use integer keys and string values. For examples using GeoID Dictionaries, see LookupTable.Value.
