Chajnantor digital elevation models

We have made digital elevation models (DEM) of the MMA site on Chajnantor to aid us in the layout of the array configurations and roads and to determine shadowing of astronomical objects by nearby mountains. The vertical scale has been exagerated to make the topography more striking. The partial mountain at the north central edge is Cerro Chajnantor and the partial mountain at the northeast corner is Cerro Chascon.

For more information, see MMA Memo 160.

And here's the Japanese Pampa la Bola site located just to the north-northeast of our site:
