If you love detailed spatial data and/or the bay area, I HIGHLY recommend downloading and exploring the readily available
Upland Goals Project Data . Ryan Branciforte introduced it to us last week during his enlightening geolunch presentation about his work with the
Bay Area Open Space Council. There is a wealth of data for all interests, including vegetation, animals, environmental features, weather patterns, fire risk, and even camp sites if you want to plan a trip to go look at all the data on the ground.
