Good day all,
I am trying to merge a large data set, the input imagery is 1TB RGB
uncompressed tifs (lots of them). Then I run gdal_merge.py on a small
data set it runs ok and with -v option I can see whats happening. But
then I run on a large dataset I don't get no verbose output (I don't
get no output at all) and it stuck on 8.9 GB image size. I can just
track that the image is getting bigger but not verbose output
whatsoever and I can tell why it stops on 8.9 GB.
My command is: gdal_merge.py -v -init 255 -of GTiff -co TILED=YES -co
COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co BIGTIFF=YES -o of.tif of/*.tif
The input images are around 160mb each so loading them 1 by 1 into
memory is not a problem.
I want to join all this imagery into 1 big tif and create overviews to
serve it via mapserver.
