Module 5: Projections (Part 1)
Above are three maps comparing different projection coordinate systems for Florida, USA. There is noticeable distortion which is exemplified in the discontinuity of county area. It should be noted that the region represented in the map is bisected by a UTM zone transition (i.e. Florida is in both UTM zone 16 and 17), but the projection uses only one UTM zone (zone 16) as reference. Similarly, there are three State Plane zones in Florida, but only one is used as reference here. As personal choice, I used the same legend style for each map as if to be actually comparing three side-by-side maps in one document.
