How to Terrain Ruggedness Index raster function

Question

I'm trying to use this Terrain Ruggedness Index (TRI) tool in ArcGIS Pro. I tried following these instructions: "In ArcGIS Pro, search ArcGIS Living Atlas for raster function templates to apply them to your imagery layer." Searching in the Living Atlas pane in ArcGIS Pro yields no results:

Am I looking in the wrong place? The instructions are really sparse and don't seem to work.

Thanks for the reply - for some reason, when I follow the same steps I don't see the TRI. In fact I'm not seeing any raster functions, only Web Maps or Imagery Layers. Maybe there's some program setting for allowing import of raster functions?

Hello

So in the Catalog pane of ArcGIS Pro:

1: Click the Portal tab.

2: Click the Living Atlas button

3: In the search box type raster function and press <return>

In the results you *should* see the Terrain Ruggedness Index (TRI) function

4: Right click the function and choose Open Raster Function.

Hopefully that should do the trick

many thanks ed
