DEFINITION The process of constructing a map, the transferring of the meridians and parallels to a flat sheet of paper. The resulting product of this geometric exercise is called a 'map projection'. This can be done in a wide variety of ways, the principle differences being projections that show accurate area over the entire map, and those that show accurate distance.

    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.
