Eight attributes (counting "type_height") hold the informations about a tile.
These attributes are referred to as - "type_height", - "m1", "m2", - "m3", "m4", - "m5", "m6" - and "m7".
+ "type_height", + "m1", "m2", + "m3", "m4", + "m5", "m6" + and "m7".
The most important value is the class of a tile, stored in the upper 4 bits of the type_height attribute. The lower 4 bits are used to encode the height and slope data.

- Special Attribute : m6. There are 4 bits of it that are used accross multiple tile classes

It allows the replacement of the properties as well as the graphics of houses in the game.
To distinguish between the standard behaviour and the newGRF one, HouseID (m4 + m3[6]) is tested for anything above 110.
110 is the count of standard houses. So above 110 means there is a new definition of at least one house @@ -1525,6 +1551,7 @@ 2  water +
