GEOG 862
GPS and GNSS for Geospatial Professionals



Discussion Instructions

To continue the discussion begun by this lesson, I would like to pose this question:

What are differences between the geoid, the ellipsoid, and the physical surface of the earth? What role do each of them play regarding the collection and expression in coordinates of GPS positions?

To participate in the discussion, please go to the Lesson 5 Discussion Forum in Canvas. (That forum can be accessed at any time by going to the GEOG 862 course in Canvas and then looking inside the Lesson 5 module.)
