> Just checked it out, and that is perfect for the intended use. The idea is to figure out the region the predictor is making a prediction for simply to generalize the area.

No problem. Enter a lat-lon and get the F-E region number and name.

The F-E number is all you need for that.

Do you need programming help? I have several programs to work with the information.
