Hi,
You could start by merging all your tiff in a VRT then do
gdal_translate -of Gtiff -co SPARSE_OK=TRUE -a_nodata 0 -co NBITS=1 -co
"TILED=YES" -co "COMPRESS=CCITTFAX4" -co "INTERLEAVE=BAND" "example.vrt"
"example.tif"

Hello all
I have ~1000 tiff/tfw RGB but with only 0 or 255 color value in all
bands
(black/white).
I want to mosaic them in a single image to be used in qgis and other
gis
software.
Which is the best way to do this? And to compress the resulting
image? May
be Tiff?? Single band??
Another problem is that I must apply a formula to input images to
transform
255 value to null, because of some white portion of each image that
overlap
to black portion of the adiacent one..
Thanks
Pietro
