Image classification on mosaic dataset

Question

If I applied color balance (or other functions to alter the color) to a mosaic dataset in a ArcMap environment, does the source raster altered? If not, then when I subsequently perform classifications on the mosaic dataset (the "image" layer in the ArcMap Table of Content), is the analysis done using the color-balanced raster or the source raster? On the other hand, if I perform classification to the mosaic dataset in ArcCatalog, is the analysis done using the color-balanced raster or the source rasters?

Hi Olivia ,

The source rasters on disk do not change but the pixel value in the mosaic items will be altered. So regardless of whether performing classification on the "Image layer" in the Contents or through ArcCatalog the analysis will be done on the color balance raster(mosaic items) not the source rasters on disk.

Thanks
