Inspired by the USGS's Sam Droege (the man behind monitorchange.org), we have a couple projects to turn park visitors into a remote sensor network! It's simple: Put up a sign asking people to set their cameras or phones in an angle bracket, take a photo, and post it with a hashtag to Twitter, Instagram, or Flickr. Then we harvest the photos and create timelapse views of change over time.
