Hi,<br>
I've been banging my head for an hour or so, and I cannot spot my
(deliberate) error in trying to clip out an area from a vrt file.<br>
<br>
<blockquote><tt><tt><b>geograph@gs01:/20150315_work/gdal$</b> </tt>gdal_translate

</tt></blockquote>
and AW25a.tif is not created.<br>
<br>
I have also tried:<br>
<blockquote>removing everything except projwin, srcdata and dstdata
- to no avail.<br>
using the computed values with -srcwin instead of -projwin<br>
putting quotes around the -co options<br>
</blockquote>
<br>
Any thoughts welcome.<br>
Thanks in advance,<br>
Zoltan<br>
