This week we’ll broach the topic of datums, coordinate systems, and map projections in the GIS class that I teach at Cornell. It’s week 5+ of the semester, just enough into this stuff so that there’s some sustained knowledge growing and they now have enough of a framework onto which to hang the obvious-but-abstract-and-necessary-but-confusing-and-powerful topic. I used to be more GIS-traditional about this stuff and dive in during weeks 2 or 3. Not any more. Much more and deeper learning taking place now that students are more confident and competent at managing and manipulating spatial data. T
Just in time, XKCD has come up with another inspired projections example to share with the class.
