<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi,<br>
I have a bunch of ecw images that I need to convert to tif+worldfile.<br>
<br>
I therefore need to recompile gdal against the ecw libraries, but the only file I can download from Intergraph/Erdas website is:<br>
ECWJP2SDKSetup_RO_20110303.exe<br>
which is a Windows install of the SDK.<br>
<br>
How do I do this for Linux?<br>
(Want to batch convert them on ubuntu 10.04)<br>
<br>
On another note, I notice that the xml files received with the ecw images only have projection info in them, and not the georeferencing info.<br>
Is the georeferencing info embedded in the ecw files (like geotiff)? I tried looking in the ecw file with a binary editor, but saw nothing obvious.<br>
<br>
TIA,<br>
Zoltan<br>
