I've installed MS4W on a WinServer2003 R2 box at work, in hopes of serving<br>
4TB of NAIP data we are about to acquire from USGS. That data comes in<br>
(JP2000) and they sent me a CD with 4 sample images to test. I've tried<br>
everything I can think of to get get MS4W to serve them. I tried pointing a<br>
layer directly at one of the .jp2 files. I tried adding the four files to a<br>
shape file index using gdaltindex. I don't think that worked, but I didn't<br>
get an error. I don't think it worked because if I open the shape file I<br>
don't see the polygons where the images should be. Nothing seems to work.<br>
I then used Global Mapper to convert the files to tifs. That works great.<br>
I can point a layer directly at a tif, and it serves it up fine. I can add<br>
the tifs to an index and I can then see all 4. I did seem to loose<br>
resolution in the conversion, and the borders of the 4 tifs isn't exactly<br>
correct, so maybe my projection is wrong? Anyway, from the documentation I<br>
think I saw that jp2 was built in? Is that correct?<br>
