I have some geo data from a collaborator with coordinates that look like this:
Grid UTM X UTM Y 30C10 696033 8967310 25C05 690997 8962938 25C05 690688 8962268
sometimes lower case (assume it's a typo?)
25c17 702859 8962900
and sometimes only one digit following the letter:
38c9 692363 8972661
These points should be in Zambia...
If I take just the first three characters as the UTM Zone (e.g. 38C) and use Perl's Geo::Coordinates::UTM to convert to WGS-84 it all looks very wrong.
Can anybody shed some light?
I am also asking the collaborator.
