Hi all, I have quite a few MrSid files that are in UTM that I want to mosaic together into some epsg:4326 tiles. I've written some python scripts to produce the appropriate gdal_warp commands to create the tiles, but they are running extremely slow.
I've read various mailing list posts and blogs about different options for MrSid like this one: http://priour.wordpress.com/2007/01/09/massive-performance-improvements-in-converting-mrsid-files/ which highlights using GDAL_FORCE_CACHING = YES to speed up a gdal_translate when using MrSids. I've also read about using GDAL_ONE_BIG_READREAD to speed things up in MapServer. Which option, or any other options, would be helpful for gdal_warp? Also, my MrSids are wrapped in VRTs to provide coordinate system info. If I use the VRTs will the GDAL_FORCE_CACHING and GDAL_ONE_BIGREAD options be used? Thanks!
