I have a general question regarding how to handle the null values with 1 band byte grey scale images. Typically I will receive a image with pixels at the edges of a image with a value of 0 however some of the interior pixel values (shadow areas) share the same pixel value. My old approach was just to ignore the interior values and run gdalwarp indicating the source and target nodata as 0.
Is there a method currently available to distinguish between valid and invalid nodata values when they both share the same pixel value? -- Travis K.
