Day 17: Busy, busy, busy

Sorry for the late blog post! Yesterday was very hectic; I was busy literally all day. James and I started the day bright and early collecting data points so we could later attempt to correct the DEM. After being out in the field for about seven hours we made it to Atlantis and decided to call it a day. It was my turn to make dinner and stir-fry was on the menu so it took Courtney, Shelby, Emily, and I about four hours to cook for twenty people. By the time we finished cleaning up it was dark out and I still had to work on the data James and I had collected. When we tried to compare the Z values from our data to the existing DEM data, we quickly realized we were obtaining Z values using the height of ellipsoid (which is good) but the DEM was in mean sea level. Not only that, but our vertical accuracy was not very good at all. This was a little discouraging and after about an hour of searching how to convert one unit of measure to another we called it a night.
