About Delta Island

Delta Island reaches 59 m above sea level down to 166 m deep by the heights of its 203 baked slots and covers 0.05 km² of the game's biome grid. The resource with the highest expected count here is Gold (about 25 per game), the creature is Skyray (about 42).

A pin belongs to the area of the nearest baked slot within 30 m (3-D, so a cave counts for its own area); a pin with no slot nearby takes the biome-map class above it (2-D). Placement of pins, depth and the spawn ranking are read from the game files; the spawn numbers are a model and have not been verified in a running game.

Depth is metres below sea level, read from slot heights. Coordinates are the game's world metres, x east and z north.
