I have a list of GPS coordinates (they should be near the coast of Guinea) and I am not sure what format they are in. After I figure out the format they are in, I want to better understand the process I should use to decide on what projection to use. Note: I have zero information except for the approximate location.
As is: (1) 1000350 1259062 (2) 959409 1258527
Here is what I've tried: Assuming they were just in decimal degrees: (1) 10.0035 -12.59062 (2) 9.59409 -12.58527
Assuming they were in d mm ss and that all the formatting was accidentally removed and doing a conversion to decimal degrees (D + M/60 + S/3600 = DD) (1) 10.01388889 -13.00055556 (2) 10.09694444 -13.11305556
While both options seem to be close to what I think they should be, they still don't look quite right!
