Dear List I have a compressed 4-band geotiff image with the 4th band being the Alpha channel. When I reproject this image to any other projection using gdalwarp or cut a a small window out of it using gdal_translate, all pixel values become 0 although in the original image they are not zeros. I think this is because the alpha channel is being interpreted as a mask band - how do I turn this off? I just want to be able to reproject the image and retain pixel values of all 4 bands (including the alpha band) in the new reprojected file.
Thank you. Mutlu.. -- Mutlu Ozdogan, Ph.D. Associate Professor Department of Forest and Wildlife Ecology & Nelson Institute for Environmental Studies t: (608) 262-0873 e: [email protected]<mailto:[email protected]>
