My numbers for warping single images or small mosaics with cubic spline option show about 12 GB/hour. However, I have tried sometimes to warp tens of gigabytes of imagery through .vrt file to a BigTIFF and that process progressed very very slow. I need to admit that I used ER Mapper and ERDAS Imagine and never bothered to investigate further what was going wrong when building mosaic with gdal. I have lot of imagery easily available and I volunteer for testing is somebody has suggestions for better gdalwarp parameters or has new program versions to try. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
