Introduction to Map Projections

Students working with maps, paper or digital, must recognize the significance of map projections. Projecting a three-dimensional globe onto a two-dimensional surface will always create inaccuracies when portraying the Earth. However, certain projections create more or less distortion depending on the type and the regions projected. This is an introductory exercise to Map Projections. Students will become familiar with the basic concepts, classifications, and controversies related to projecting the Earth. They will use ArcView GIS to compare, contrast, and finally to choose appropriate map projections from a global perspective as well as a regional perspective.
