GIS Programming

I have been programming and working with database applications for over 30 years, and specializing in geospatial applications for over 20 years.  I am a believer in the 80/20 pareto principle which suggests that you only need to understand 20% of a subject in order to do 80% of your work. My goal in all my courses is to teach at the level of that 20% sweet spot and to provide my students with the background and the tools they need to learn the rest of what they need on their own.
