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 identifier 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 Royal Lakes: 2399138
GNIS ID for Macoupin County: 424257
GNIS ID for Illinois: 1779784
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 Royal Lakes:
| Place (Community) Code: | 66165 |
| State Code: | 17 (Illinois) |
| County Code: | 117 (Macoupin 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: | 17/66165 |
| State/County Code: | 17/117 |
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 | |
| Macoupin County: | 17/117 | 424257 | |
| Royal Lakes: | 17/66165 | 2399138 |
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 Royal Lakes, it is a point within Royal Lakes 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 Royal Lakes, the GNIS GPS location is given as:
Lat: 39° 6' 42" (or 39.11°)
Lon: -89° 57' 38" (or -89.96°)
Determined by its statistical needs, the Census Bureau has defined a sampling area for Royal Lakes - 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 Royal Lakes, the Census 2010 GPS location is given as:
Lat: 39° 6' 47" (or 39.11°)
Lon: -89° 57' 30" (or -89.96°)
The map point defined by the Census Bureau lies 833 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: 39° 6' 45" (or 39.11°)
Lon: -89° 57' 42" (or -89.96°)
The GPS location given for the 2000 Census lies 987 feet to the west<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. Royal Lakes is located in Region #2 (the Midwest Region).
In turn, the US Census Bureau has further divided each Region into Divisions. Royal Lakes is located in Division #3 (the East North-Central Division).
The Office of Management and Budget (OMB) has created ten Federal Regions. Royal Lakes is located in Region V (Region 5).
The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Royal Lakes is located in Region V (Region 5).
