- JPEG2000 raster format has internal pyramids.*
- With ArcGIS versions 10.x, pyramids can be built for the JPEG2000 format. It seems this wasn't possible with 9.x versions of ArcGIS**
- Is there a reason why only for the JPEG2000 format pyramids can be created, but for other raster formats with internal pyramids like ECW & MrSID, pyramids cannot be created?
