I am trying to clip a polygon grid based on a point layer as well as another polygon.

Basically I have a polygon grid and a layer of points that fall in the center of most of the cells. I want to keep only the grid cells that have a point within them. In addition, I have a county boundary polygon (partially shown in orange) that I want to use to further clip the grid, but I want to keep whole cells only. It's OK if the cells fall partially outside of the county boundary as I want to make sure I have full coverage of the entire county.

I am slightly familiar with ModelBuilder if that is the best way to go.

  • The question indicates 'polygon grid', so it looks to be a fishnet. – Radar Jan 13 '14 at 23:20

To do this I would:

  1. Use Clip on your points first
  2. Use Select Layer By Location using your "clipped points feature class" against your "grid feature class" and INTERSECT as the spatial relationship
  3. Right-click on the "grid feature class" layer in the Table of Contents and Export | Export Data
  • If the point layer is clipped by the boundary polygon first, followed by the steps @PolyGeo outlines above, this should achieve a solution to the entire question. – Radar Jan 13 '14 at 23:22
  • This worked! Thank you so much! I ended up doing it in reverse order from what Radar suggested, but the final result was the same. – Katie Jan 13 '14 at 23:34
