buffering points & combining the overlapping areas into one

[Cummings, Mike]

I thought I had done this before (and I thought it was easy); but I’ve been trying for awhile & I can’t seem to get it right.  I have a bunch of points, some of which are grouped together (spaced about 25’ apart in a line or two).   What I would like to do is identify where these points are and be able to count the group as one; to determine the number of locations for these points and be able to say how many points are associated with each location.

 

I have created buffers around the points.  What I can’t get right is combining the overlapping regions to create one region for the group.  There are too many to combine them individually; anything I do will have to done to all.  I’m I trying to do something that I will need to write code to do?

Mike,

You need to combine them all into one single polygon as a first step.

Then you can use the disaggrate function in the Objects menu to disaggrate the "buffers" that don't touch.

I hope this makes sense

Yes it does.  Thanks.  I it had been a long time since I had done anything with buffers, I couldn’t remember how I had done it.
