We've added Green Castle to our Gazetteer with the hope that we can develop more information. If you can help us with Green Castle, please Contact Us.
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 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 Green Castle: 465429
GNIS ID for Johnson County: 465240
GNIS ID for Iowa: 1779785
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.
While FIPS codes have been assigned to all counties and states, a specific code has not been assigned to Green Castle. The following FIPS codes apply to the State and County:
| State Code: | 19 (Iowa) |
| County Code: | 103 (Johnson County) |
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 Green Castle, it is a point within Green Castle 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 Green Castle, the GNIS GPS location is given as:
Lat: 41° 46' 28" (or 41.77°)
Lon: -91° 39' 58" (or -91.67°)
Regional Codes ...
For statistical purposes, the US Census Bureau has divided the country into four Regions. Green Castle would have been located in Region #2 (the Midwest Region).
In turn, the US Census Bureau has further divided each Region into Divisions. Green Castle would have been located in Division #4 (the West North-Central Division).
The Office of Management and Budget (OMB) has created ten Federal Regions. Green Castle would have been located in Region VII (Region 7).
The Federal Emergency Management Agency (FEMA) has created ten Management Regions. Green Castle would have been located in Region VII (Region 7).

Footnotes ...
| <1> | We use the term 'Historic' broadly and it generally means that the community no longer exists. However, it can also mean that the community might still exist, but was significantly larger or had a more 'official' existence in the past than it does now. Unfortunately our sources of data have proven to be unreliable. If you can provide us with more specific information about Green Castle, please let us know so that we can improve our accuracy. |
