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 Warren, it is a point within Warren 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 Warren, the GNIS GPS location is given as:
Lat: 44° 1' 39" (or 44.03°)
Lon: -89° 4' 12" (or -89.07°) [Map]
Determined by its statistical needs, the Census Bureau has defined a sampling area for Warren - 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 Warren, the Census 2010 GPS location is given as:
Lat: 44° 1' 34" (or 44.03°)
Lon: -89° 3' 48" (or -89.06°) [Map]
The map point defined by the Census Bureau lies 1,862 feet to the east<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: 44° 2' 1" (or 44.03°)
Lon: -89° 4' 42" (or -89.08°) [Map]
The GPS location given for the 2000 Census lies 4,840 feet to the northwest<2> of the point given by the 2010 Census.
