Ambient Occlusion Map

Ambient occlusion is a measurement of how much ambient light reaches a point on a model based on how much the point is occluded--or blocked--by other parts of the model. Corners, creases and crevices tend to be very occluded, causing them to have dark shadows even when the rest of the model is well-lit.

An ambient occlusion map indicates how occluded each area of the model is.

Often for models with only diffuse maps, the effects of ambient occlusion are "burnt into" the diffuse map. Areas that would be made dark by ambient occlusion are simply painted a darker color.

Here is the ambient occlusion map:
