 Hello, I'm Fritz Kessler, one of the faculty in the MGIS program. I'm here to talk about a course I designed titled, The Earth is Round and Maps are Flat, Spatial Reference Systems in GIS. In this class, you'll develop a working knowledge of datums, map projections, and grid systems. Datums such as NAD 83 define Earth's size and shape and are important in establishing horizontal and vertical control. Map projections such as the molevita transform Earth's spherical surface to a map. Grid systems such as the UTM allow locations on Earth's surface to be described in a Cartesian coordinate system. In short, this class will give you a foundation to understand the differences between the many datums that exist and learn the appropriate transformation to use when changing from one datum to another. Familiarize yourself with different map projections and how to define the parameters. Examine a map projection, explain its distortion pattern, and understand how that distortion pattern impacts the use of the map for a given purpose. Work with grid systems, how they're set up, and their limitations. If you work with geospatial data in a digital environment and don't know the difference between PUCLOVO 42 from ISO anamorphism, then you need to sign up for this class.
