I'm trying to convert a 20 GB LZW compressed geotiff to a tilepyramid using gdal2tiles.Unfortunately, gdal2tiles seems not to be able to handle this, after running it for 10 hours it still hasn't reached the first "dot" yet. I tried this with a smaller (1GB) file and it worked fine. My question now is, is there any other software that allows me to do this (commercial or open source)? One can create tiles from GlobalMapper, but I cannot load the 20GB file into memory.
