3維GiS數據與Django和Postgis

Question

我可以在我當前的項目中使用第三個維度，強烈涉及谷歌地圖和Django。我如何處理這個問題？

class Waypoint(models.Model): 
    latlng = models.PointField() 

>>> p = Point(5, 10, 20) 
<Point object at Ox...> 
>>> p.kml 
'<Point><coordinates>5.0,10.0,20.0</coordinates></Point>' 
>>> w = Waypoint.objects.all()[0] 
<Waypoint: Waypoint object> 
>>> w.latlng = p 
>>> w.latlng.kml 
'<Point><coordinates>5.0,10.0,20.0</coordinates></Point>' 
>>> w.save() 
>>> w = Waypoint.objects.all()[0] 
<Waypoint: Waypoint object> 
>>> w.latlng.kml 
'<Point><coordinates>5.0,10.0,0</coordinates></Point>' 
          ^

注意第三diemsnion被忽略。哎呀！
