Map Projections

The most interesting thing I learned this week with the lab was how much a map differs based on the projection the data is based off of.  While sometimes the difference is faint (visually), there are times that certain projections will cause a significant distortion on the map you are working with.  

So this week we focused on the map projections: Albers, UTM, and State Plane N.  While it is difficult to visualize the differences in the map below, the data that is presented in the table shows how much the square mileage of select counties differs across the three projections.  See for yourself below.  If you have any suggestions on how to make this better, feel free to comment below.
