CH 2 Notes

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.

My software is finally installed on my computer! Thanks to Professor Pete. I am very happy I didn't have to spend 100 dollars and buy a dvd drive. Things are looking up.
Here are some notes on Chapter 1. GIS helps gather and use spatial data. GIS components include hardware, software, data/info, protocols/procedures, and people. ARC Catalog is the file management tool for spatial data. ARC Map is used to edit/analyze and manage data. Points, lines, and polygons are used to display things on a map.

GIS 1st Blog

Well, I've had a rough time in the class so far. My computer doesn't have a dvd drive so I haven't been able to install the software for this class. Luckily we finally figured out that was the problem, so now I just have to get a dvd drive put on my computer and hopefully the software with work. If not I think my head might just explode!
