Frank, <br>thanks for your reply.<br><br>I have already properly set the GDAL_DATA var :(. (And the cited file ecw_cs.wkt is present there)<br>Here's why I investigated for a Proj4 responsability.<br><br>Which type of permissions problems do you think should be involved?
(I'm using Windows Vista and GDAL_DATA links to a simple folder
C:\work\gdal... As an instance I know that Vista may introduce some
problems in several circumstances when working with C:\ProgramFiles...
Moreover I have disabled User Account Control some months ago...)<br><br>Thanks a lot. I will narrow my search for the cause of the problem. <br><br>Regards,<br>Daniele<br><br><br><div class="gmail_quote">On Feb 12, 2008 3:04 PM, Frank Warmerdam <<a href="mailto:warmerdam@pobox.com">warmerdam@pobox.com</a>> wrote:<br>
