I have one polygon layer (shp) of areas, and a point layer converted from a raster file. The points have categories as they were converted from a raster, which should correspond to the polygon value, however I wish to make a validation table of it.
I want to summarize the values of each point within each polygon as such:
polygon type A
-------------------
number of points type A
number of points type B
polygon type B
--------------------
number of points type A
number of points type B
number of points type C
Spatial join would work?
Thank you very much in advance.
Solved! Go to Solution.
OK, Summarize Within is only in Pro I think.
In ArcMap, you could still do Spatial Join: http://desktop.arcgis.com/en/arcmap/latest/tools/analysis-toolbox/spatial-join.htm
and Summary Statistics: http://desktop.arcgis.com/en/arcmap/latest/tools/analysis-toolbox/summary-statistics.htm
But if you have an ArcGIS Desktop license, you should also have ArcGIS Pro - it is a part of ArcGIS Desktop...
Have you tried a spatial join and not getting the results you expect?
If you use a spatial join, you then might need to summarize the output to group the number of points by attribute. You could use the Case Field in https://pro.arcgis.com/en/pro-app/tool-reference/analysis/summary-statistics.htm
So instead of doing that, you might want to try Summarize Within and use the Group Field: https://pro.arcgis.com/en/pro-app/tool-reference/analysis/summarize-within.htm
Thanks for the quick reply. I'm not finding these tools in the toolbox, I have Arc Map 10,6. Is it something extra?

That was what I was looking for, thanks very much for the replies.
