Miscellaneous Information
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 new 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 numeric code 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 Twin Grove: 423261
GNIS ID for McLean County: 1784833
GNIS ID for Illinois: 1779784
FIPS Codes ...
In a past effort, various federal agencies worked together to create 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 Twin Grove:
| Place (Community) Code: | 76511 |
| State Code: | 17 (Illinois) |
| County Code: | 113 (McLean 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: | 17/76511 |
| State/County Code: | 17/113 |
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 Illinois: | 17 | 1779784 | |
| McLean County: | 17/113 | 1784833 | |
| Twin Grove: | 17/76511 | 423261 |
GPS Location - GNIS Coordinates ...
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 Twin Grove, it is a point within Twin Grove 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 Twin Grove, the GNIS GPS location is given as:
Lat: 40° 29' 36" (or 40.49°)
Lon: -89° 4' 47" (or -89.08°)
Regional Codes ...
For statistical purposes, the US Census Bureau has divided the country into four Regions. Twin Grove is located in Region #2 (the Midwest Region).
In turn, the US Census Bureau has further divided each Region into Divisions. Twin Grove is located in Division #3 (the East North-Central Division).
The Office of Management and Budget (OMB) has created ten Federal Regions. Twin Grove is located in Region V (Region 5).
The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Twin Grove is located in Region V (Region 5).
