I am working with ArcGIS Pro 2.3 (am able to upgrade to 2.8 if that brings in a new tool I need).

Is there a way to simplify a polygon feature class so each polygon has a maximum of 250 vertices?

There are 715 records and so manually doing this is not an option.

  • As per the help center please do not include chit chat like thanks in your posts. If you wish to ask for help with Python/ArcPy code then you'll need to included a code snippet that illustrates what you've tried and where you're stuck.

    What is your data? why 250 vertices? Are there polygons in your data already less than 250 vertices? What are you will to accept as a simple blunt approach is to strip of the last X vertices so that it hits your 250 limit but this would change the shape of your polygons. Please add this information to your question, some screen shots would help too.

  • As Hornbydd suggests, this is not a good way to simplify features, and also lacks information about which vertices to drop. There are algorithms for simplifying features that would prioritise removing vertices that add little or no information (e.g. those on straight sections of an edge). These don't target particular total numbers of vertices per polygon as that is rarely a sensible thing to do. Dec 5, 2022 at 0:00

Please refer Genaralise and Simplify tools with reference to tolerance using arcpy/geoprocessing tools. but shape out will happens. After output need to check the vertices count and accordingly with given tolerance.
