They are necessary if you plan to color balance the raster dataset. These are the statistics of the source raster datasets within the mosaic dataset. To calculate statistics on the mosaic dataset, right-click the mosaic dataset in the Catalog window and click Calculate Statistics the Calculate Statistics tool opens. When building overviews, statistics are generated automatically. However, if your mosaic dataset has overviews, the statistics are generated using the overviews. Number of columns by 1,000 and use the quotient (integer) as the One way to identify a reasonable skip factor value is to divide the This is why it is recommended that you use a skip factor. When you calculate statistics for a mosaic dataset, the base pixels are examined that is, the source raster datasets with the lowest pixel sizes are examined and the statistics are generated across the entire mosaic. These statistics are applied to the entire mosaic dataset when it is displayed.
