I have a data set with 2 layers of objects. For the purpose of this question, lets say one layer is pipe, and the other layer is valves. I need to know if I can define a point (any point I choose) as a center point, and then be able to select (and have a reported count) of all the valves within a 2 mile radius of the center point.
I am new to this data world, and also new to this tool (I just got a 60 day evaluation license to try this kind of thing)
select by spatial location is (or select by location) is what you are after, .... this differentiates if from select by attributes
Select By Location: graphic examples—Help | ArcGIS for Desktop
Also,
You Can Run Point Distance Tool ( Point Distance ).in 2 mile distance (search distance), then make summarize for Input_FID field. You will get the count of points from result table .
