Mosaic Dataset Statistics

[BruceBurwell]

Hi

I am trying to calculate statistics on a mosaic dataset. I have used several different options including right clicking and selecting Calculate Statistics and using the Build Pyramids and Statistics option in ArcToolbox. For one of my mosaic datasets it is not calculating statistics for the overall mosaic dataset but when I check the raster images in the footprint file, each image has statistics calculated. So I can do a stretch using the From Current Display option but not using the From Mosaic option. I assume after I load all the imagery into the mosaic dataset, I should run Build Pyramids and Statistics option in ArcToolbox (forcing stats and pyramids on the source data as well but only for the 1st time) and stats will be calculated for the mosaic dataset. If I then create a new mosaic dataset pointing to the same source data, I would then need to just calculate statistics for the mosaic dataset and not the source data.

Thanks

Hi Bruce,

Yes, the mosaic dataset has several ways to calculate statistics, and it holds different kinds of statistics also. This can be confusing. There is a help topic for this online. Please try to calculate statistics for the mosaic dataset using the calculate statistics geoprocessing tool. For speed you could specify a skip factor if you want. This should definitely work.
