I have point data from a proprietary source that came in a coordinate system I do not recognize. Here is an example:

Lat: 35205357 Long: -11.15933

It looks like a combination of UTMs and incomplete dds. This is supposed to be in or around Flagstaff, AZ.

What is this coordinate system?

    Welcome to GIS SE. Could you please name the proprietary source (doing it in the question via edit would be good)? – Martin F Dec 3 '14 at 23:04

I just entered the coordinates into Google maps. If you change them to 35.205357, -111.59330 it puts you in the Flagstaff area. So The coordinates may have just had their decimal places in the wrong places or missing.


The latitude value could be 35 20 53.57 while the longitude value could be -111 59 33. Or they could both be decimal degrees, with the appropriate insertion or change of position.
