Notes:

• The data format is tab-delimited ASCII.
• REGIONS.PDF -  Adobe Acrobat document that shows the character set mapping used to display diacritics and special characters in the FULL_NAME, SHORT_FORM, and GENERIC fields of the data sets per region.
• CCN1.HTM / CCN2.HTM - List of Country Codes and Names sorted by Country Code (CCN1) and by Country Name (CCN2).
• Designations:   Their Codes and Definitions -  A list of designation codes and their definitions.

Field Name and Description

Field Name Field Description
RC Region Code.  A code that determines the character mapping used in the FULL_NAME field (refer to REGIONS.PDF):
1 = Western Europe/Americas;
2 = Eastern Europe;
3 = Africa/Middle East;
4 = Central Asia;
5 = Asia/Pacific;
6 = Vietnam.
UFI Unique Feature Identifier.  A number (int) which uniquely identifies the feature.
UNI Unique Name Identifier.  A number (int) which uniquely identifies a name.
DLAT Latitude of the feature in decimal degree:
+ = North;
- = South.
DLONG Longitude of the feature in decimal degree:
+ = East;
- = West.
LAT Latitude of the feature in degrees, minutes, and seconds [ąddmmss]:
+ = North;
- = South.
LONG Longitude of the feature in degrees, minutes, and seconds [ądddmmss]:
+ = East;
- = West.
UTM Universal Transverse Mercator coordinate grid reference.
JOG Joint Operations Graphic reference.
FC Feature Classification:
A = Administrative region;
P = Populated place;
V = Vegetation;
L = Locality or area;
U = Undersea;
R = Streets, highways, roads, or railroad;
T = Hypsographic;
H = Hydrographic;
S = Spot feature.
DSG Feature Designation Code.  A two to five-character code used to identify the type of feature a name is applied to.
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 (Blank) as a value for populated places with unknown or undetermined classification.
CC1 Primary Country Code.  A two alphabetic character code uniquely identifying a geopolitical entity (countries, dependencies, and areas of special sovereignty).
ADM1 First-order administrative division.  A two alphanumeric character code uniquely identifying a primary administrative division of a country, such as a state in the United States.
ADM2 Second-order administrative division.  A subdivision of a first-order administrative division, such as a county in the United States.
DIM Dimension.  Usually used to display elevation or population data.
CC2 Secondary Country Code.  A two alphabetic character code uniquely identifying the country code of a particular name if different than that of the feature.
NT Name Type:
C = Conventional;
D = Dagger or not verified;
N = Native;
V = Variant or alternate.
LC Language Code.  A two alphabetic character code uniquely identifying a language of a country if multiple official languages are used.
SHORT_FORM A specific part of the name that could substitute for the full name.
GENERIC The descriptive part of the full name (does not apply to populated place names).
SORT_NAME A form of the full name which allows for easy sorting of the name into alpha-numeric sequence. It is comprised of the specific name, generic name, and any articles or prepositions.  This field is all upper case with spaces, diacritics, and hyphens removed and numbers are substituted with lower case alphabetic characters.
FULL_NAME The full name is a complete name which identifies the named feature. It is comprised of the specific name, generic name, and any articles or prepositions (refer to REGIONS.PDF for character mapping).
FULL_NAME_ND Same as the full name but the diacritics and special characters are substituted with Roman characters (refer to REGIONS.PDF for character mapping). ND = No Diacritics / Stripped Diacritics.
URL Empty field used as a place-holder for standard GIS output.
