Great Smoky Mountains National Park, Tennessee/North Carolina, November 2001
I brought my GPS along on our hiking trip and recorded our path
(Download the path data here).
Later, I downloaded the
USGS maps for the area. I had to splice two of them together, which took some doing. Then I manually laid the
path onto the map in Photoshop and tried to get it to fit. As you can see, it didn't quite fit. I attribute
this to GPS error, operator error, and some to the map, which was last updated in 1976. Some day I hope to
come up with a more automated process.
