      Map projections are an important part of GIS and geography in general. Different projections offer  certain types of information or project certain information better or more accurately than other maps. For example, one map might be better for measuring distances while the other is better for mapping elevation. Location can also play a big part in the desired map projection.
      If a person needs a top view of the earth around the north pole, a mercator or behrmann map wouldn't be the best choice. A equidistant conic map would be a more suitable option in that case. Picking the right map projection is crucial for finding the distance between two points as the distance exercise in this lab clearly demonstrates. The distances are up to 3,200 miles apart between the GCS 1984 and the mercator maps, which even on a global scale, is a massive difference in milage.
