summarize raster values to polygon

RobertSchwartz

#summarize raster; #raster values to polygon

Working with ArcGIS Pro, I can't find an easy solution to what I used to be able to do in ArcGIS with XTools Pro: extract raster values to polygon, which allowed for zonal statistics to be created for each polygon: sum, mean, standard deviation, min, max, etc. My interest is "value" from a raster, i.e., elevation.

Can this be done in ArcGIS Pro? The ArcGIS Pro tool "Summarize Elevation" limits the number of polygons to 1000. I have 3000.

Thanks,

Robert Schwartz

Thanks, Dan. Eventually that worked. At first I was looking for a way to get the desired values directly into the polygons. You used to be able to do so in ArcMap using XTools Pro surface tool, Aggregate by Attributes. But you have to careful there to chose Polygon as the aggregation geometry. I didn't at first.

Spatial analysis in ArcGIS Pro 2.4

-properly projected raster and surface extent to the polygon extent

-zonal statistics to table

-verify polygon layer projection = to raster projection

-join the table to the polygon layer

-check for problems

Thanks, Dan

Yes, that method eventually worked once I used a raster whose extent

matched the extent of my polygon. What I wasn't sure about was whether

the table would join correctly with the polygon. Happily it did.

Thanks,

Bob
