How to remove polygons that intersect points

JoseSanchez — Thu, 29 Nov 2018 14:46:55 GMT

Hello everyone,

I am looking for a way in Model Builder or Python te delete all the polygons from a layer that intersect points from another layer.

The goal is to have a polygon layer with polygons that do not have any matching point in the point layer.

How can I do that?

If you can do it manually with tools from arctoolbox, then you have the basis for a model.

Is there a particular problem that you are running into?

The goal is to find porperties (polygons) that do not have meters (points).

We worked with Model Builder and we were able to find the properties that have a meter with Select Layer By Location and then to find the properties without meter we used the erase tool removing "Select Layer By Location" polygons to the initial Properties.

Thanks

I don't believe the (expensive) erase step is needed, you should be fine with a Select Layer By Location of property polygons containing a meter point, and check the box to invert the selection. Then you will have all polygons selected that do not contain a meter point. You can then Copy Features to copy these meter-less polygons to a new feature class.
