On Friday, September 7, 2007, we had a lecture on Chapter 3. Chapter 3 is about "Geodesy, Datums, Map Projections and Coordiinate Systems. Geoid's is based on the gravitational movement of the earth. "Geodesists have defined the geoid as the three-dimiensional surface along which the pull of the gravity is a specified constant." pg. 73; paragraph 2, GIS Fundamentals.
We also spoke about the test Tommorrow and we were requested to watch the video by ESRI,
Working with Map Projections and Coordinante Systems in ArcGIS. One of the examples used in the video was, how to project data on the fly. The video was informative and the instructor Milita kennedy asked 3 review questions during the presentation.
We also done Chapter 13 and posted the map to our blog.
