Summarize Raster Within

ThilinaSurasinghe1

I am looking for a tool to calculate mean across multiple rasters. I am aware of cell statistics tool that can be used here. I am also aware that raster calculator can also be used here. But, in my research I came across time tool: "Summarize Raster Within: Summarize Raster Within—RasterAnalysis Tools | ArcGIS Desktop 

However, I cannot locate this tool in my version of ArcGIS Pro 2.4.3. The tool I could find were for polygons (summarize within), not for rasters. 

This tool was refereed to in this tread. Any guidance on use of this tool will be greatly appreciated.

Cell statistics allows you to do it in batch mode, however, you can only vary the statistics type, not the input rasters.

This is how you would "batch" a tool in any event.  Using Zonal Statistics as an example.

If your rasters are all for the same area (ie stacked up over time) then you can use arcpy's RasterToNumPyArray to process statistics at a local level.

I have a number of blog posts on how to use arcpy and numpy to do things that aren't builtin to ArcGIS Pro or ArcMap

plus others...

and a bit dated
