<pre wrap="">The performance vs size when zooming out is impressive with ECW, but it
does not look like I have ability to create ECW. Are there better

JPEG2000 or MrSID are somewhat similar to ECW.

<font face="Times New Roman, Times, serif">Hi Even, are there any
benchmarks to compare (uncompressed) gtif with the three formats
above? My production maps are always tiled to 2000*2000 pixels,
all zoomlevels precomputed. Very efficient with uncompresssed
gtif, but they take lots of space. How much slower are these
formats?<br>
