Hi,

Using gdal_merge.py to merge multiple Geotif files and get the following error? Is there a work around to the size issue? Expected output file size is about 12 Gigs. I was under the impression gdal was able to handle Big TIFF format. If not, can you please suggest a format available in Gdal that I can use which will support large rasters?

gdal_merge.py -o tot.tif Port*.tif

ERROR 6: A 53888 pixels x 35904 lines x 3 bands UInt16 image would be larger than 4GB
but this is the largest size a TIFF can be.  Creation failed.
Creation failed, terminating gdal_merge.

Thanks,

Vytas
