Terrain subfiles

Terrain Map (0xa9dd6ff4)

This subfile contains the terrain information of a city tile. A completely flat city, as generated by the game when creating a new region, will have 270 as height for every vertex. Default water level of the game is a few meters below.

Structure

Note: the terrain map is one of the few Savegame subfiles that does not include a CRC checksum. This has been used to great advantage: programs like SC4 Terraformer populate this subfile. If this file would have used a CRC checksum, then such tools would not have been possible as long as the CRC checksum algorithm wasn't known (which was only the case 16 years after the game's release!)
