We have loaded some high resolution imagery (2005) into ArcSDE 9.1 (oracle)
using JPEG2000 compression (quality level 150). We have noticed the draw
speed for this imagery is very slow. We have the same imagery for 2003
that we loaded with JPEG compression, and it draws instantly. Basically
the only differences is the compression type. We have built pyramids,
analyzed the block table, used various oracle optimization techniques, but
nothing seems to work. Anyone else out there run into this? Any
solutions? Thanks!
