You should be familiar, by now, with the basic spatial analytical capabilities of GIS since you have been performing many of them in your labs (both 270 and 370). However, since the contents of Chapters 13, 14 & 15 in your text, or in Chapters 7 & 8 in GIS Basics, and Chapters 5, 6 & 7 in Geospatial Analysis, cover a range of material, in this lecture I will cover an eclectic selection of the methods of spatial analysis.
Learning Objectives
- Be able to decide whether a method is spatial by asking whether its result changes when the objects move.
- Be able to explain why the Euclidean distance between two places can differ from their geodesic, network or travel-time distance.
- Be able to build a spatial weights matrix from a stated definition of neighbour.
- Be able to explain what testing a pattern against complete spatial randomness can show.
- Be able to explain how the kernel's distance parameter changes a kernel density surface.

Chapters 5, 6 & 7 of the Geospatial Analysis online text covers much of this material. (If you are in the GIS Minor stream you should definitely review the material presented in this online text.)
Useful Resources
ArcGIS Resources: Spatial Statistics Resources
A very useful resource--for those who really want to delve into spatial analysis, local and global spatial autocorrelation, and much more--are the recorded lectures of Luc Anselin from the University of Chicago.
GeoDa--the program I demonstrated in class that was developed by Luc Anselin. A very useful program with which to explore spatial data and try out different spatial data analysis tools.
