Learning Objectives:
Describe the visual appearance of the Earth’s graticule
Discuss what a Tissot indicatrix represents and how it can be used to assess projection-induced error
Interpret a given a projected graticule, continent outlines, and indicatrixes at each graticule intersection in terms of geometric properties preserved and distorted
Illustrate distortion patterns associated with a given projection class
Recognize distortion patterns on a map based upon the graticule arrangement
Explain the kind of distortion that occurs when raster data are projected
Explain the rationale for the selection of the geometric property that is preserved in map projections used as the basis of the UTM and SPC systems
Recommend the map projection property that would be useful for various mapping applications, including parcel mapping, route mapping, etc., and justify your recommendations
Define the four geometric properties of the globe that may be preserved or lost in projected coordinates
Explain the concept of a “compromise” projection and for which purposes it is useful
