I have a large shapefile with polygons. Some of them have roads between them, but apparently the roads have been deleted. Therefore, there is only space between the polygons. I want them removed in ArcMap. I need my solution to be automated since the data is large so snapping and such cannot be used. What I could think of was to add in the roads shapefile but I am not sure where to go from there. I was thinking I can have the polygons meet half-way, at the middle of the space (roads) between them.

Any idea how to do that?

This is how my map looks like now:

  • Thanks for pointing that out. I added a pic of my map. The desired output would be for the gap to be removed.

  • I would just create a polygon around your data in a separate feature class and Union the two feature classes. Then clean up any unwanted fields added by the process.

  • Thanks. Sorry I'm kinda new to ArcMap - how would I create a polygon around my data?

  • If it's an exact rectangle then you could use Create Fishnet to create a single polygon vector grid.

You can try using the AutoComplete polygon.

These are a few supporting documents that you can refer to for a better understanding.

Fill the space between polygon features

Creating adjoining polygons
