Hi List, I have a 4 Bands (RGB-IR) GeoTIFF for which I also have an external mask.tif which has been created starting from a mask.shp shapefile using this command:
*gdal_rasterize -ot Byte -l mask -CO "TILED=YES" -CO "NBITS=1" -CO "PHOTOMETRIC=MINISBLACK" -CO "COMPRESS=DEFLATE" -a cat -burn 1 -ts 16384 16384 mask.shp mask.tif* So that my mask.tif is 1 bit B/W GeoTIFF. Now, I would like to add it as Internal Mask of the main GeoTIFF. I have played a bit with GDAL translate and buildvrt and, due to constraints on number of bands, I ended up with this commands: *gdalbuildvrt -b 1 1.vrt origin.tif gdalbuildvrt -b 2 2.vrt origin.tifgdalbuildvrt -b 3 3.vrt origin.tif * *gdalbuildvrt -b 4 4.vrt origin.tif * In order to separate the bands Then: *gdalbuildvrt -separate out.vrt 1.vrt 2.vrt 3.vrt 4.vrt mask.tif * in order to re-aggregate them into a single raster, together with the mask. And finally: *gdal_translate -of GTIFF -CO "PHOTOMETRIC=RGB" -CO "ALPHA=NO" -CO "TILED=YES" -CO "COMPRESS=DEFLATE" -b 1 -b 2 -b 3 -b 4 -mask 5 out.vrt final.tif* So that I copy the 4 bands from VRT and add the 5th band as mask. I have 2 issues with that: 1) This solution is really not optimal. Wondering if there is a single command to attach an external tif as a mask band of an existing raster (provided it has same CRS, resolution, bbox, ecc) 2) What I get is that the mask has been set as an external file final.tif.msk. Is there any config option or opening option to open the final.tif in update mode so that the band mask can be added as internal geotiff mask? Please, let me know what do you think about it.
