This week we are focusing on map projections. Choosing the correct projection for a map is an important consideration. To demonstrate the variation that occurs between map projections, we highlighted four Florida counties and calculated the area represented by their respective geometry. As you can see from the side-by-side maps above, there is considerable variation in the areas of each county in the differing projections. The UTM Zone 16N projection shows the most distortion in Miami-Dade county as UTM 16N only really covers the panhandle portion of the state. Since Miami-Dade is furthest east from the 16N/17N boundary, it exhibits the most distortion of the four counties.
