</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 :-).<br>

<tt>Our provincial DEM is a 3.5GB Geotiff which is of 48800x58000 size.<br>
