Capturing pre- and post-burn imagery in "gigapixels"

UC Davis has done it again, this time with "gigapixel" imagery of the Clavey River confluence, before and after the Rim Fire.  A gigapixel image contains more than 100 times the information captured by a typical 10 megapixel digital camera.  Gigapixel imagery is a product of NASA, Google, and Carnegie Mellon University efforts to develop imaging technologies for NASA Mars rovers.  The technique has been used in Yosemite Valley to document rockfall hazards, and as UC Davis has illustrated, gigapixel imagery has potential for broad application in watershed and river management to document changing landscapes over time.
