Treat symbol overlap
Issue #23
new
If more objects have identical coordinates or are very close one to other(s), the map should express it. * The symbol should contain a number (digits) expressing the number of objects at the same location; such uniting should depend on the map zoom. * If various types of objects have the same location, a priority of their types or special combined designs should be used * a click on the location of completely or partly overlaping symbols should open a popup to select from the objects, none object should be inaccessible.
Could we deal the problem as this way?
