</tt><tt>I've dealt with ERDAS Imagine files larger than 10 GB on a regular basis. I have occasionally tried to reproject and merge all of the 1 m NAIP imagery tiles for North Carolina into 1 BigTIFF > 500GB with gdal. Any parallelizaion work for open source geospatial tools would be welcome :-).</tt></p>
</div></blockquote><div>So you "tried" to do that? Does that mean you failed or is the system still processing it? :-P I kid, but that is a very large file... it's bigger than my current desktop's hard drive. <br>
