Hi, GDAL people, I am trying to make a thumbnail from a GeoTIFF image using gdaladdo and am confronting a problem. My GeoTIFF file is ALOS AVNIR2 file (4 bands).
After browsing the mannual (http://www.gdal.org/gdaladdo.html), I tried the following command: $ gdaladdo -ro --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL ALAV2A273212850-OORIRFU.RCRefG.GEO.tif 16 then I got the following errors: ERROR 6: PHOTOMETRIC_OVERVIEW=YCBCR requires a source raster with only 3 bands (RGB) Overview building failed. All I want to do is create a small true-color jpeg image (RGB=321) from the 4 band satellite image in GeoTIFF format. I appreciate your suggestions. -- Kenlo Nishida Nasahara Faculty of Life and Environmental Sciences University of Tsukuba, Japan 305-8572 [email protected] _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
