Hello,
I am trying to georeference already georeferenced single band raster data
using GDAL with four GCP's.
Input image is having Coordinate system GCS- WGS1984 (EPSG:4326).
Following Command is run on command Prompt:
*"gdal_translate -of GTiff -gcp 72.4819 23.0179 72.4819 23.0179 -gcp 72.492
2
OK, digging deep into my old emails I think I found a solution ( still
to be proved):
gdalwarp -t_srs EPSG:4326 -r bilinear -co TILED=YES -co BIGTIFF=YES
-dstalpha -multi '00010.jp2' '/data/satmap/tmp.tif'
This took 39 min and expanded the 2.1G jp2 into 87G tif, then this gets
followed by:

Hi,
If your datasets are large you should not create plain JPEG files with the
GDAL JPEG driv
Right, but the point 1 is the message says:
ERROR 6: PHOTOMETRIC=YCBCR requires a source raster with only 3 bands (RGB)
ie: requires a source raster with only 3 bands (RGB) and the source
raster has only 3 bands!
-dstalpha if I understand correctly is to create a alpha band in the
output file. S
Steve,
Setting that alpha channel makes it 4 bands. RGB + alpha channel. Either remove
the ycbcr or the alpha channel.

Hi all,
I'm trying to convert a utm jp2 file to a wgs84 tif file and getting
"ERROR 6: PHOTOMETRIC=YCBCR requires a source raster with only 3 bands
(RGB)" but the src file has only 3 RBG bands.
gdalwarp -t_srs EPSG:4326 -dstalpha -r bilinear -of GTiff -co
BIGTIFF=YES -co TILED=YES -co COMPRE
