style='font-size:10.0pt;font-family:"Trebuchet MS";color:black'>Currently, I am
trying to reproject some Mr.SID images from UTM NAD83 to USGS Albers. Seems
easy enough and it should be. In fact, I have had a great deal of success
doing it with GDAL. And that’s the problem. Sometimes it
works perfectly, other times not at all. If things consistently failed,
then I would know that the problem was with me. However, since it works
intermittently, I am completely perplexed. <o:p></o:p></span></font></p>

examples of what I am trying to do. In both instances, I have succeeded
before and failed before. When gdalwarp fails, I get a Widows error
telling me that “gdalwarp.exe has encountered a problem and needs to
close.” On that note, I should add, I am running XP pro with all service
packs installed.<o:p></o:p></span></font></p>
