GIS 4303 Week 5

Week 5 covered projection, how to reproject and how to adjust coordinate systems for different layers.  Also learned how to map multiple data frames.

This map is showing three different projections: UTM, Albers, and State Planar.  To create this map, three separate data frames were required.  I started with one shapefile of Florida and used the Project tool to change the projection into two other coordinate systems creating new layers.  Looking at the map of all three, it is clear to see how Florida changes under the projections.  The area of the four specific counties have changed from projection to projection.  The changes in area can also be seen in the legends.

This lab is one of the most important to understand.  Projection is key to creating an accurate map.  If the projection is off, locations won't be portrayed correctly.  Different data will be in various projections which is why it is important to learn how to change the coordinate system to a usable one.
