Shadow map - lay this on top of topographical data

If you could somehow take this data and apply it in three dimensions on top pa topographical map/data to determine how topographical contours would produce shadows given the position of the sun at any time of year. It would be particularly useful in a hilly city like San Francisco where the moutons cast shadows on whole neighborhoods at certain times of the year.

This would be really helpful for anyone suffering from Seasonal Affective Disorder.
