HI List/Tim,
Thanks to all who responded.
My first guess, UTM39N, based on the numeric value of the coordinates
and the fact that the area was somewhere in Doha, was correct.
But, when I looked at the result, the polygons did not match nicely with
the Qatar coastline.
Today I get confirmation from the original source, that it is in fact
UTM39N, and.....wait for it...(drum-roll).......the polygons represent
CLOUD COVER. (Doh! of course they don't follow the coastline)
So, it is obviously never too late to learn that asking what the vectors
represent, might be key to solving your problem.
Big thanks again to all who responded.
Kind regards,
Zoltan
