I have a set of tree classifications that have been acquired from a different software and have loaded them into ArcMap. I am wanting to find the main tree clusters and have had no problem doing that, by buffering them. but the problem is that the rule set created for the classification has included long linear areas which are not required. Some areas branch off from the main clusters and are therefore included in my final tree cluster area. I am therefore in need of a method that can help me remove these long linear polygons whilst keeping the main clusters. Can anybody help please?
