I would like to use pyramid levels to speed up raster classification for large rasters, e.g. use a level other than level 0, e.g. level 1, to calculate the histogram, calculate the breaks on level 1 and then apply those breaks to level 0.
However, I can't figure out how to actually extract the level 1 raster (in this example) and get the pixel values of same.
I'd appreciate any advice on what I'm trying to do.
Thanks!
Anything? Basically, I need to know how to export OVR files to separate rasters...
