Explain the categories of map algebra operations (i.e., local, focal, zonal, and global functions)

Explain why georegistration is a precondition to map algebra

Differentiate between map algebra and matrix algebra using real examples

Perform a map algebra calculation using command line, form-based, and flow charting user interfaces
