When it comes to get new seamless tiles, for my mind I have received just perfect results with gdalwarp by using the following command: gdalwarp -s_srs EPSG:2392 -t_srs EPSG:25835 -tr 0.5 0.5 -te 402000 7182000 408000 7188000 Jpeg2000.vrt EUREF_mapsheet.tif Essential here is to use a virtual mosaic as a source file. A modified gdal_merge script was once posted to gdal_dev mailing list, that creates GDAL/VRT file from a file list in seconds. In practise I feed the extents of the resulting images and corresponding file names as variables from another bat-file calling this one. There is no need to separately put new tiles together, everything will be ready with one run. Regards, -Jukka Rahkonen-
