Jarod Raithel  created a truly exceptional map for this lab.  He was able to put  quite a bit of information on a single map.  He had a short, yet descriptive paragraph, which mad it easy to understand the difference between the DEM's resolution.  Being able to describe different resolutions  is important because many people are unaware of that file size is a direct reflection of pixel size.  Remember it is very important to know what resolution to use for a given project, knowing this can and will save you (and the computer) from a headache.
