I need to make a map of voronoi from polygons about a certain attribute in arcgis Pro, since it is an arcmap function and I need the same function in arcgis pro and I can't find it

Is this what you're looking for? Which function did you use in ArcMap?

Thiessen polygons only works with points, not with polygons
In Arcmap
With Geostatistical Analysis -> explore data -> voronoi map.

Hi Liliana,

Unfortunately, the Voronoi Map tool is not available in ArcGIS Pro.  Most Exploratory Spatial Data Analysis (ESDA) tools from ArcMap are available as charts in ArcGIS Pro, but the Voronoi Map is not one of them.

Thanks, but Do you know another similar tool to voronoi map in Arcgis pro? or another idea that help me.

Hi, I just noticed that you were asking about creating a Voronoi Map from polygons rather than points.

If you just need the geometry of the Voronoi Map and do not need the local statistics, you can do the following:

  • Convert the polygons to point centroids using "Feature To Point" geoprocessing tool.
  • Use the centroids as input to "Create Thiessen Polygons" tool.
  • Optionally, clip the Thiessen polygons to a boundary using the "Clip" tool.

This will give the same polygons as the Voronoi Map ESDA tool in ArcMap.  Again, it will not have the local statistics, but it will create the same polygons.
