Hi list, Following this up, I've decided to go the GeoTIFF/BigTiff route with inner tiling and overviews based on Andrea's document. But unfortunately there doesn't seem to be any documentation on the GeoServer pages about this stuff. I've never used GDAL before and generally avoid the command line (there's a reason we're trying for GeoServer not MapServer ;-) ) so am not sure where to start. My source input is hundreds/thousands of LZW compressed GeoTIFF tiles. These need to be mosaiced together (I can do that in FME easily enough). But then what? Do I compress them at this point? Or inner tiling? Or Overview? Does it matter what order these things are done? And what settings should I use? For instance Andrea's document gives a "blocksize" of 512, but Jukka's comments were on the order of 10,000 and the default is 256. Is there a tutorial out there on this I've failed to find?
