A colleague pointed out the National Land Cover Database (NLCD) imagery today, which is not new, but it is useful. Here is a simple treatment of the San Francisco Bay Area, with city center markers matching the red urban coloring used in the base map. Click for the larger image, and you can see Lake Tahoe in the East and unmarked is Yosemite National Park almost due south. (’06’ in the blog post title refers to both the publication year of this base map, 2006, and the FIPS code for the State of California)
