as a MrSid format file, but once you uncompress it ( I suggest using gdal's
nearblack utility ) to ERDAS Imagine format, the resulting image will probably
be in the multi-gigbyte range per county.</font></a></p></blockquote><div>Well that's good. It only took overnight for 500 GB? That doesn't sound too bad. I'm not looking for huge maps, but some decent-sized samples would be good for testing. Thanks for the resource I'll look into it if I need some samples for testing. The warning at the bottom the site is a bit nerving though... I'm not a government official.<br>

Our provincial DEM is a 3.5GB Geotiff which is of 48800x58000 size.<br>
Another file which I recently had to import was a 4GB Geotiff with<br>
21550 bands. Finally, in remote sensing, you can quickly generate<br>
quickly files in the multi-GB range.</font></tt><font size="3"><br>
