I'm not sure exactly what you mean...

Firstly, terrains are modified at vertex level rather than being a tile-based thing.

If for some reason you want to store your terrain data in an array, you can do something like this:-

Terrain = CreateTerrain(256)
Dim TerrainArray(TerrainSize(Terrain),TerrainSize(Terrain))
For X = 0 to TerrainSize(Terrain) - 1
  For Y = 0 to TerrainSize(Terrain) - 1
    TerrainArray(X,Y) = TerrainHeight(Terrain,X,Y)
  Next
