Since quiz #1, we have discussed quite a bit of information related to Techniques in GIS, including working with data tables, data acquisition and related issues (quality, standards, error, accuracy, precision, etc), GPS and the transition from GPS to GIS, and some information related to Analysis in GIS including georeferencing, geoprocessing, and some of the more commonly used geoprocessing tools. Below is a list of a few of the many things that you should be familiar with from our lectures for Quiz #2. In other words, don't just study only the information suggested below, but all of your notes, handouts, and web content since Quiz #1.
