De moment, el concepte de zona pot ser extensiu a un riu o una muntanya. Durant la creació del mapa, podeu mantenir en la vostra ment quina muntanya o riu serà objecte del treball. En aquest exemple el riu tindrà el color & lt; 20, 76, 34gt; com a identificador.
Of course, the division concept can be extended to a river or a mountain. During the creation of the map, you should keep in mind that most times the river or mountain will be too small that you should provide an additional clicking area. In this example the river would have the maroon area and color & lt; 20,76,34gt; as its identifier.
