Last fall I gave a talk at the U.S. Geological Survey’s Earth Resources Observation and Science Center (EROS), near Sioux Falls, S.D. It was my second talk on why and how to build a national, online database for ground photos like those we have for aerial and satellite imagery.


After the previous talk I posted the slideshow with audio, and now I am again. The second picks up where the first left off, so you may want to watch in order. Thanks to the staff at EROS for their hospitality, their feedback and their original ideas. I look forward to further collaboration.
