Region Font Code.  A code that determines the character mapping used in the SHORT_FORM, Generic, and Full_Name fields (see Character Set Conversion Table [Char_Sets_20060703.pdf],:


1 = Americas/Western Europe;
2 = Eastern Europe;
3 = Africa/Middle East;
4 = Russia/ Central Asia;
5 = Asia/Pacific;
6 = Vietnam.
number Y
UFI Unique Feature Identifier.  A number which uniquely identifies a Geoname feature. number Y
UNI Unique Name Identifier.  A number which uniquely identifies a name. number Y
LAT

Latitude of the Geoname feature in ± decimal degrees; DD; (± dd.dd...):
no sign (+) = North; 05°03'09''E » 5.0525

negative sign (-) = South; 05°03'09''S » -5.0525
number Y
LONG

Longitude of the feature in ± decimal degrees; DD; (± dd.dd...):
no sign (+) = East;

negative sign (-) = West.
number Y
DMS_LAT

Latitude of the Geoname feature in ±degrees, minutes, and seconds; DMS; (±ddmmss):
no sign (+) = North;

negative sign (-) = South.
number Y
DMS_LONG

Longitude of the Geoname feature in ±degrees, minutes, and seconds; DMS; (±dddmmss) :
no sign (+) = East;

negative sign (-) = West.
number Y
MGRS Military Grid Reference System coordinates character Y
JOG Joint Operations Graphic reference.
These maps are based on the format of standard 1:250,000 medium-scale military topographic maps, but they contain additional information needed in joint air-ground operations. Along the north and east edges of the graphic, detail is extended beyond the standard map sheet to provide overlap with adjacent sheets. These maps are produced both in ground and air formats. Each version is identified in the lower margin as either Joint Operations Graphic (Air) or Joint Operations Graphic (Ground). The topographic information is identical on both, but the ground version shows elevations and contour in meters and the air version shows them in feet. Layer (elevation) tinting and relief shading are added as an aid to interpolating relief. Both versions emphasize airlanding facilities (shown in purple), but the air version has additional symbols to identify aids and obstructions to air navigation.
character Y
FC

Feature Classification: Nine (9) major Geoname feature categories into which similar feature designations are grouped.
A = Administrative region type feature
P = Populated place type feature
V = Vegetation type feature
L = Locality or area type feature
U = Undersea type feature
R = Streets, highways, roads, or railroad type feature
T = Hypsographic type feature
H = Hydrographic type feature
S = Spot type feature

character Y
DSG Feature Designation Code.  A two to five-character code used to identify the type of Geoname feature a name is applied to.
(see more at Feature Designation Code Help)
character Y
PC Populated Place Classification.  A graduated numerical scale denoting the relative importance of a populated place.  The scale ranges from 1, relatively high, to 5, relatively low.  The scale could also include NULL (no value) as a value for populated places with unknown or undetermined classification. number Y
CC1 Primary Country Code.  A two alphabetic character code uniquely identifying a geopolitical entity (countries, dependencies, and areas of special sovereignty). character Y
ADM1 First-order administrative division code. A two alpha-numeric code from the FIPS 10-4 Standard describing a primary administrative division of a geopolitical entity, such as a state in the United States. character Y
ADM2 Second-order administrative division.  The name of a subdivision of a first-order administrative division, such as a county in the United States. variable character Y
DIM Dimension: Holds Population/Elevation Figures. If the Feature Classification is "P", Populated place type feature, then the value is Population Figures. For all others, the value is Elevation number N
POP Population Figures. number Y
ELEV Elevations (in meters, decimal values accepted). number Y
CC2 Secondary Country Code. A two alphabetic character code from the FIPS 10-4 Standard uniquely identifying the country code of a particular Geoname feature name if different than that of the primary country code of that Geoname feature (International features). character Y
NT

Name Type:
C = Conventional name
N = BGN** Standard name
NS = BGN** Standard name in non-Roman script
P = Provisional name
PS = Provisional name in non-Roman script
H = Historic name
HS = Historic name in non-Roman script
D = Not verified or daggered name
DS = Not verified name in non-Roman script
V = Variant or alternate name
VS = Variant name in non-Roman script
. . .** BGN = U.S. Board on Geographic Names

character Y
LC Language Code. A three alphabetic character code (ISO 639-3) uniquely identifying the language assigned to a Geoname feature name. character Y
SHORT_FORM A part of the full name that could substitute for the full name. variable character Y
GENERIC The descriptive part of the full name such as Mount, River, or Sea (generally does not apply to populated place names). variable character Y
SORT_NAME A form of the full name that allows for alphabetical sorting of the file into gazetteer sequence. All character/diacritic combinations and special characters are substituted with QWERTY (visible U.S. English keyboard) characters, all characters are upper-cased, numerals are converted to lower-case characters (0-9 = a-j), spaces are stripped out, and commas replaced with space.  The substitution is done according to a character mapping table that is Region Font Code specific (see Character Set Conversion Table [Char_Sets_20060703.pdf].  This field is included for the benefit of the end user of the data to aid in the sorting of names if required. variable character Y
FULL_NAME The full name is the complete name that identifies a named feature.  The full name is output in reading order, "Mount Everest", vs. reversed generic, "Everest, Mount", as stored in the database. variable character Y
FULL_NAME_ND Same as the full name but the character/diacritic combinations and special characters are substituted with QWERTY (visible U.S. English keyboard) characters while still maintaining casing and spaces. The substitution is done according to a character mapping table that is Region Font Code specific (see Character Set Conversion Table [Char_Sets_20060703.pdf].  ND = No Diacritics / Stripped Diacritics. variable character Y
MODIFY_DATE The date a new feature was added or any part of an existing feature was modified (YYYY-MM-DD). date-time N
