Seems to be in a State Plane format
~ Captain Paul's response to: ~ Jayson 172 ~
I believe that the coordinates you listed are in a format of STATE PLANE, but I am not completely sure as I donít have a topographical map of Nebraska to be able to accurately plot the position in the state plane format. The State Plane format is a form of Universal Transverse Mercator (UTM) grid format, but stated in feet rather than meters.
Generally, the format would look something like 15T N. 44571480.0 E. 0255270.0. This position is for the center of the MISSOURI RIVER at the I-480 bridge in Omaha. It is normally called Northering ~ Easterling in zone 15T. The numbers represent meters north of the equator and east of the east~WEST boundry zones edge.
Aside from that, I donít believe that the MISSISSIPPI RIVER passes in OMAHA. You may want to double check the figures you have and if correct, plot them in the State Plane format.
