DM-55 - Map projection parameters

Learning Objectives: 
  • Explain how the concepts of the tangent and secant cases relate to the idea of a standard line
  • Implement a given map projection formula in a software program that reads geographic coordinates as input and produces projected (x, y) coordinates as output
  • Identify the parameters that allow one to focus a projection on an area of interest
  • Use GIS software to produce a graticule that matches a target graticule
  • Identify the possible “aspects” of a projection and describe the graticule’s appearance in each aspect
  • Define key terms such as “standard line,” “projection case,” and “latitude and longitude of origin”
