I am using an IconLayer in NASA World Wind (Java SDK) to show positioned items on a map which works fine except for when several are in a group and start to overlay one another. The display of the icons in a group like that is not so much of a problem as I need to allow the end user to easily select the correct icon in that "pile" easily. A workaround would be to allow for a right-click on an icon in that group would generate a context menu that shows a list of the items in that "pile" so they could select the one they want.
Creating a context menu on right-click is easy enough but I do not see how I could create a buffer from that point to do a simple geometry relationship like "contains" in NASA World Wind. I have searched the API a bit and have not seen anything that looks like it has potential so I was hoping that someone here might now of either how to do this in NASA World Wind or a simple way of including or achieving this functionality.
