DM-53 - Map projection properties
- 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
