Various Identification Codes ...

GNIS Codes ...

The U.S. Board on Geographic Names (BGN) was created to address the problems caused by spelling and naming variations. The BGN will usually recognize an existing name or, when necessary, establish a name for a geographic feature (such as a mountain, lake, river, stream, city, town, village, dam, bridge, etc).

The BGN names are kept in a database called the Geographic Names Information System (GNIS) and it is the official Federal repository. The GNIS is operated and maintained by the U.S. Geological Survey (USGS).

A unique and permanent number has been assigned for each name in the GNIS database. These names and identifiers are definitive and it is intended that they are to be used by all departments of the Federal Government:

GNIS ID for Keystone: 1267444

GNIS ID for Pennington County: 1266995

GNIS ID for South Dakota: 1785534

FIPS Codes ...

In a past effort, various federal agencies created a set of codes with a purpose similar to the GNIS codes. These codes are called the Federal Information Processing Standard (or the FIPS 55 codes). Although they are still used by some organizations, the FIPS codes are obsolete and will ultimately be replaced by the GNIS codes.

The following FIPS codes apply to Keystone:

Place (Community) Code:  33820
State Code:  46 (South Dakota)
County Code:  103 (Pennington County)

Since the Place and County FIPS codes are not unique and can be repeated in other States, it's necessary to combine the State code with the Place and County FIPS codes to uniquely identify them - for example:

State/Place Code:  46/33820
State/County Code:  46/103

As already mentioned, the FIPS codes are to be replaced by the GNIS codes. The following reflect those changes:

 FIPS Code   translates to   GNIS Code
State of South Dakota:    46   1785534
Pennington County:    46/103   1266995
Keystone:    46/33820   1267444

GPS Location - GNIS vs Census ...

An important aspect of the GNIS code is that it assigns a GPS location (the latitude/longitude) to the geographic feature. This location is simply a point on the map and does not represent the size or shape of the feature. In the case of Keystone, it is a point within Keystone that might be a post office, the city hall or simply an intersection - the point should really be considered arbitrary and only indicating a general location.

For Keystone, the GNIS GPS location is given as:

Lat:   43° 53' 39"   (or 43.89°)

Lon:   -103° 25' 45"   (or -103.43°)   [Map]

Determined by its statistical needs, the Census Bureau has defined a sampling area for Keystone - this area also contains a map point. As with the GNIS code, the location of the Census point should be considered as being arbitrary within the sampling area.

For Keystone, the Census 2010 GPS location is given as:

Lat:   43° 53' 43"   (or 43.9°)

Lon:   -103° 25' 35"   (or -103.43°)   [Map]

The map point defined by the Census Bureau lies 815 feet to the northeast<1> of the point given by the GNIS (see above).

You might note that the GPS location given for the 2010 Census is different than the location that was specified by the 2000 Census:

Lat:   43° 53' 37"   (or 43.89°)

Lon:   -103° 25' 33"   (or -103.43°)   [Map]

The GPS location given for the 2000 Census lies 672 feet to the south<2> of the point given by the 2010 Census.

Regional Codes ...

For statistical purposes, the US Census Bureau has divided the country into four Regions. Keystone is located in Region #2 (the Midwest Region).

In turn, the US Census Bureau has further divided each Region into Divisions. Keystone is located in Division #4 (the West North-Central Division).

The Office of Management and Budget (OMB) has created ten Federal Regions. Keystone is located in Region VIII (Region 8).

The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Keystone is located in Region VIII (Region 8).
