In lab 2 we will learn how different projections affect the way a map represents information to the user. Building on our introduction to ArcMap in Lab 1, we will learn how to change projections in the data view and how to accurately use the measure tool. After completing this assignment we will be able to explain why different projections are used for specific purposes. Make sure all measurements are in MILES. Copy data from R drive to X drive folder, or to your local drive at home, or jump drive. When you add a layer, a red ! may appear. Link the source to your X drive, or whichever drive you are working from. Reminder : Remember your Las Pulgas map for next week.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
