I'm trying to divide a closed boundary into sub zones. These sub zones will be of shapes based on a road network. I have tried split tool but it is not working for this.
What tool should I use?
I am using ArcMap 10.8.

What do you mean by not working? Can you add a screenshot?– BeraCommented Dec 10, 2020 at 9:38

By not working, I meant that I'm split isn't the right tool for this. Or I don't know the use of split for this purpose– snowCommented Dec 10, 2020 at 10:12

This doesn't seem to be possible with standard functionality, but please see here: gis.stackexchange.com/questions/31965/… or here: gis.stackexchange.com/questions/30586/…– BerendCommented Dec 10, 2020 at 10:38

Features to polygon will do it. You can select parts belonging to original polygons after.– FelixIPCommented Dec 11, 2020 at 3:18

1 Answer
- Convert the polygon into polyline
- Merge the Polyline with road network
- Convert the merged feature class back into polygon
This would create sub-polygons for all you area that has been intersected with you boundary.
However this may have some problems in the corners where the roads do not intersect the border.
