I have a '90's era Air Force Crash Report. The coordinates are listed as an 8 digit number with a decimal after the 4th digit. As an example 2037.0590 does anyone know how this number is created and how to decipher to a standard lat long?
Thanks

A derivative of UTM called MGRS.

The Army reports have those as well.  

You need to know the general location because the MGRS coordinate has letters from a grid system and the full coordinate would look more like this: 10S FF 2037 0590 or 11S PA 2037 0590 or whatever 6-8 degree grid designator then 100,000 meter grid square you think it should be in.

There is a converter here:

Use the national grid index map to derive the full MGRS coord and convert it to Lat/Long.

One nice thing though is that with an 8-digit MGRS if you can figure out the zone and grid square it should put you within 10 meters of the crash site.
