I created the following map to show how three different projections impact land area calculations in square miles.  This information can be used to illustrate the importance of using consistent map projections when analyzing multiple data sets.  This also illustrates the importance understanding your projections and using the correct projection for the type of information you want to convey.  Inconsistencies in use of projections or a lack of understanding in how projections work can lead to errors in data analysis and promote erroneous ideas.  The State Plane projection appears to be a nice balance between the Albers and UTM projections in terms of consistency when analyzing data for the state of Florida on the county level.  Topography along county lines and coastline areas may influence how these projections calculate area and effect the final result.

Prior to making this map, I collected data on safety signs in Fort Davis, Texas.  The exercise of collecting data helped my to understand how real world conditions can impact data collection and allowed me to think through potential pitfalls that I would not have if I had not done this exercise.  Also, the experience with using different file types and interactive applications was very beneficial for when I might apply these principals in the real world.
