Are you trying to meet a friend for lunch? Post your location or just "check in" where you are. Want to see if there's a quick way out of traffic? Pull up GPS. Although many districts, and even states, have given up teaching geography classes, the utility of the discipline keeps increasing. From tracking packages you buy online to storms approaching your area. Geographic Information Systems (GIS) are the ultimate combination of data analysis and practicality. As schools move away from filling in maps of far away countries to project and inquiry-based curriculum aimed at explaining the world's challenges as well as solving them, a new approach to geo-literacy is gaining ground. And with the ubiquity of mapping software in our digital world, students may just be perfectly placed to take notice. As geographer Joseph Kerski explains, the reason that GIS is so important is because, "the data that goes into...GIS has to do with real places, real environments, real people." So let's get down to business.
