Dear all, I apologise if this is answered elsewhere, but I cant find it. I have a point layer and a polygon layer (created from the point layer using local convex hull isopleths). I would like to be able to select only those points laying within the multiple polygons (all in same layer). Is there a way to mask a point layer with a polygon layer? Even if I can just select the points inside I can then export them to a new layer. Any ideas? Thanks.

Arcmap 9.3.1

You can select the points that fall within a polygon by using the Select By Location tool. On the Main Menu toolbar, go to Selection>Select by Location. You'll want to select features from your point layer are within your polygon layer.

Thanks very much! I had a feeling it might be something straight forward, but a classic example of you only know when you know.... Thanks again. – elusival Feb 28 '11 at 16:13

From the ArcMap menu: Selection-->Select By Location.
