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