GEOG 583
Geospatial System Analysis and Design



In this lesson, we have taken a look at the range of evaluation methods available for gauging the results of each step in GIS Design. As you have seen, there are lots of types of evaluation, and evaluations can be formal or informal depending on the time/capital resources you have at your disposal. There are simple low-cost methods you can use that require no technology at all, and there are more advanced methods that require substantial technology investments. In our reading assignment, you encountered a couple of (quite different) academic studies on evaluating GIS systems that hopefully suggest some good ideas (and some limitations) you can take to heart with respect to evaluations you might conduct in your future work.

This week, we covered an emerging technology trend of eye-tracking - an expensive evaluation option, but one that yields some very interesting and compelling results on what users see as they interact with software. It wasn't very long ago when eye-tracking systems were so complicated, expensive, and unwieldy that all but a few eye-tracking expert academics were practically excluded from using the method.

We also practiced the skill of creating and posting screen-capture videos. Videos are a great way to create interest in a project or idea. They can also be useful for technical support. The ease with which anyone can make and post videos is an example of the rapid pace of technological change we have had over the last decades - such things would have been an impractical research project not too long ago.

The next lesson completes our journey through GIS System Analysis & Design, and you will focus entirely on deliverables related to your 583 Term Project.
