How do I create several tiled MrSID files from a single GeoTIFF?
The Blue Marble Desktop's Raster Tiling job can do this for you. You can load in your image file, set the parameters for your tiles (either the number of tiles, or the tile size), and write out a series of gridded or non-gridded tiles with custom naming options to many popular raster formats.
