Chapter 2 was way 2 long. In class we had a lecture on data models, it was pretty confusing, atleast to me. We learned that the two models are vector and raster. Vector models model points, lines, and polygons, which are features. Vector models things that have a distinct starting and stopping point, using symbology. It is a complex data structure. Raster data models continuous data such as temperature and elevation.
A big point was made on the difference between topology (a branch of geometry) and topography (the lay of the land) so I am writing this on here to make sure I don't forget this for the test.
