Terrain data is saved with cartesian x,y coordinates

4 types of terrain data.

• hexagon terrain data
  
    woods hexagon terrain example 
  
  uses a hexagonPoint coordinate : Terrain will be will be referenced by a point at the center of the hexagon.


• hexside terrain data
  
    river hexside terrain 
  
  uses a gridPoint coordinate : Terrain will be referenced by a midpoint at the center of the hexside.


• path terrain data
  
    road path terrain  (hexsides and centers to create a path)
  
  uses a gridPoint coordinate : Terrain will be referenced either by a midpoint at the center of the hexside or by a point at the center of the hexagon.


• hexside edge data
  
    slope hexside edge terrain 
  
  uses a edgePoint coordinate : terrain attached to the edge of a hexside. Terrain will be referenced by a point at the midpoint between the center and the hexside.

Example terrain types with a coordinate type.

• road : gridPoint
• river : gridPoint
• woods : hexagonPoint
• slope : edgePoint
• hill : hexagonPoint
• city : hexagonPoint
• town : hexagonPoint
