[GIS] Where is Summarize Raster Within tool in ArcGIS Pro

arcgis-prosummarizing

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 "Summarize Raster Within: Summarize Raster Within— Raster Analysis Tools.

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.

The Summarize Raster Within tool was refered to at GeoNet.

Best Answer

The Summarize Raster Within tool:

Summarizes a raster based on areas (zones) defined by the first input layer.

Its Licensing Information indicates that to use this tool requires an ArcGIS Image Server license.

If you do not have that license, then that may be why you are unable to find and use that tool.

Honestly, I would just calculate a focal variance. Variance within a 3x3 window is very close to TRI [sqrt(sum(dev^2)]. The variance would also be more scalable than TRI which is limited to a square 3x3 window. You could use the raster calculator to calculate an algebraic approximation of the index.

ArcGIS (type) syntax:

s = FocalStatistics(dem, NbrRectangle(3, 3, MAP), "SUM", "")
d = (dem * dem)
t = FocalStatistics(d, NbrRectangle(3, 3, MAP), "SUM", "")
tri = sqrt( t + 9 * d - 2 * dem * s )

There are several geomorphometric indices available in the ArcGIS Geomorphometry & Gradient Metrics toolbox that would provide alternatives to TRI. There is an actual implementation of TRI, that provides optional corrections and standardization of the index, in the R spatialEco package available on CRAN or GitHub.

Try Focal Statistics:

Calculates for each input cell location a statistic of the values within a specified neighborhood around it.
