| GNS Data Column | Key | Description | Why Useless | 
| UNI |  | Unique Name Identifier.  A number which uniquely identifies a feature name. | A Feature may have more than one name, so which name will be referenced? UFI identify the feature better.
There is a possible of repeating the feature with every new name if importer relying in UNI to identify features

| Another in use tags referencing this column: | 
| ADM1 |  | Primary administrative division code. A two character alpha-numeric code from the Geopolitical Entities and Codes (formerly FIPS 10-4 standard) that describes the primary administrative division of a feature, similar to a state level in the United States. For a description of these codes/values, please see the Look-up Tables.... | The value is coded so it must be decoded and put in is_in:state=*.The location of feature and boundary in OSM may describe primary administrative division better.

| Another in use tags referencing this column: | 
| RC |  | Region Font Code.  A code that determines the equivalent characters used when generating the SORT and NO DIACRITICS (ND) feature names information rendered in Roman script. 1 = Americas/Western Europe;
 2 = Eastern Europe;
 3 = Africa/Middle East;
 4 = Russia/ Central Asia;
 5 = Asia/Pacific;
 6 = Vietnam.
 | The renderer will choose font according to the country and locale of name. | 
| Another in use tags referencing this column: | 
| FC |  | Feature Class: Nine (9) major feature categories into which similar feature designations are grouped. 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

| Another in use tags referencing this column: | 
| MGRS |  | Military Grid Reference System coordinates. MGRS is an alpha-numeric system for expressing UTM/UPS coordinates. A single alpha-numeric value references an area that is unique for the entire earth. | It is another format of location |

| Another in use tags referencing this column: | 
| CC1 |  | Primary Geopolitical Code. A two alphabetic character code from the Geopolitical Entities and Codes (formerly FIPS 10-4 standard) that uniquely identifies a feature's primary geopolitical entity (countries, dependencies, and areas of special sovereignty). This field can contain one, or multiple comma separated non-spaced country codes to identify international (shared) features that run through multiple countries for up to 255 characters (example: Danube River - AU,BU,EZ…).
 | must decoded and stored in is_in:country=*The location of feature and boundary in OSM may describe country better.

| Another in use tags referencing this column: | 
| DMS_LAT |  | Latitude of the feature in degrees, minutes, seconds and hemisphere (DMSH) - dd:mm:ssH, where H is either N (North) or S (South) Note: In this format, DMSH values should be interpreted from left to right.
 | It is another format of location | 
| Another in use tags referencing this column: | 
| DMS_LONG |  | Longitude of the feature in degrees, minutes, seconds and hemisphere (DMSH) - ddd:mm:ssH, where H is either E (East) or W (West) Note: In this format, DMSH values should be interpreted from left to right.
 | It is another format of location | 
| Another in use tags referencing this column: | 
| LONG |  | Longitude of the feature in ± decimal degrees; DD; (± ddd.dddddd): no sign (+) = East;
negative sign (-) = West. 
 | Duplicated, must be in Node attributes. | 
| Another in use tags referencing this column: | 
| LAT |  | Latitude of the feature in ± decimal degrees; DD; (± dd.dddddd): no sign (+) = North;
negative sign (-) = South
 | Duplicated, must be in Node attributes | 
| Another in use tags referencing this column: | 
| FULL_NAME_ND |  | Full name - reading order with no diacritics. 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. This field also includes non-roman script based names which are stripped of vowel markings. | Duplicated, must be in name=* | 
| Another in use tags referencing this column: | 
| FULL_NAME |  | Full name - reading order. 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". | Duplicated, must be in name=* | 
| Another in use tags referencing this column: | 
| SORT_NAME_RO |  | Sort name - reading order. A form of the full name that allows for alphabetical sorting of the file into gazetteer sequence. For Roman script names, 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 and hyphens are stripped out, and commas replaced with a space. Additionally, for non-roman script names in languages using Arabic based letters. , vowel markings/pointers are removed. This field is included for the benefit of the end user of the data to aid in the sorting of names if required. | This column used internally in thier server only | 
| Another in use tags referencing this column: | 
| NT |  | Name Type: C = Conventional: A commonly used English-language name approved by the U.S. Board on Geographic Names (BGN) for use in addition to, or in lieu of, a BGN-approved local official name or names, e.g., Rome, Alps, Danube River.
N = Approved: The BGN-approved local official name for a geographic feature. Except for countries with more than one official language; there is normally only one such name for a feature wholly within a country.
D = Unverified: A name from a source whose official status cannot be verified by the BGN.
P = Provisional: A geographic name of an area for which the territorial status is not finally determined or not recognized by the United States.
 VA = Anglicized variant: An English-language name that is derived by modifying the local official name to render it more accessible or meaningful to an English-language user.
V = Variant: A former name, name in local usage, or other spelling found on various sources.
 NS = Non-Roman Script: The non-Roman script form of the BGN-approved local official name for a geographic feature. Except for countries with more than one official language; there is normally only one such name for a feature wholly within a country.
DS = Unverified Non-Roman Script: The non-Roman script form of a name from a source whose official status cannot be verified by the BGN.
VS = Variant Non-Roman Script: The non-Roman script form of a former name, name in local usage, or other spelling found on various sources.
