I want to map a tree survey. I am thinking that I will plot positional points of the trees and then add other data like tree type etc. to the attribute table later. Is there a way I can have an attribute that describes a radius or diameter, whichever is easier, of a circle round the point. In fact I need two circles, one to describe the canopy radius/diameter and another to do the same for the root protection area.
Am I going about this the right way or is there a better methodology?
