Is there a function in ArcGIS 10.5.1 that can split a polygon (black outline) based on the location of data points (red circles)? I need it to simply make a divide in between different groups of points, which is in this case group 1 and 2 (see image).
This is untested but I would try this workflow:
- Run Thiessen Polygons to create polygons from your points
- Clip the result using your black polygon, if necessary
- Dissolve using the field that stores the group values
