We have been using the GIS 20 for our class for the last three years, and the students really like it. Unfortunately, some of the sections no longer work due to changes in ArcMap, the Census Bureau website, and other issues. I have contacted Esri Press and the author and heard nothing back. If there is going to be a version for Pro, that would be great too. Otherwise, we'll need a new book that covers what our students need without taking too much time. I haven't seen anything else I like so far. Anyone know where I can get information on the future of the GIS 20 or an alternate text?
