Hi all �?? I have been trying to build a large mosaic (> 400 scenes) with the mosaic dataset. The major issue so far is with the Color Balancing function.
I´m aware that color balancing can only take place if the following is true about the data:
               All the bands have their statistics calculated.
               All the bands have their histograms built.
               All the raster datasets have the same number of bands. -
               All the raster datasets have the same pixel type and pixel depth. Only 8-bit unsigned and 16-bit unsigned bit depths are supported.
               None of the raster datasets have an associated color map
However, the statistics result seems distorted and this may be compromising the color balance. For example, the digital numbers mean are close to the maximum value (65536) and this s certainly not true.
My dataset comprises of RapidEye as received from the distributor with 16bits.
I really appreciate if anyone has some thoughts on my problems.
