https://community.esri.com/t5/arcgis-spatial-analyst-questions/problem-with-calculating-mean-aspect/m-p/1003053#M11045 <P>I would like to calculate the mean aspect of my smaller sample areas in a larger area. I wanted to use the CalcZonalMeanAspect.py file from <a href="https://community.esri.com/t5/user/viewprofilepage/user-id/12168">@CarlBeyerhelm</a>&nbsp;, but for some reason it doesn't work.<BR />After specifying the shapefile that covers the smaller sample areas, even though I specify the ESRI grid file for the height values of the area, it writes that it is not an esri grid file. However, I used the ArcMap "Raster to other format" tool to convert the original tiff file to an esri grid file.</P><P>Does anyone have any idea what might be wrong or how else I could calculate the mean aspect?</P><P>Many thanks!</P> Thu, 19 Nov 2020 18:00:13 GMT JoViviana 2020-11-19T18:00:13Z https://community.esri.com/t5/arcgis-spatial-analyst-questions/problem-with-calculating-mean-aspect/m-p/1003053#M11045 <P>I would like to calculate the mean aspect of my smaller sample areas in a larger area.
