The bigger topics (SAGA GIS, data sources, Word tricks, etc.) get turned into series of how-to posts, and the smaller questions inspired a series of vocab posts. Today we're talking about the words Euclidean and Cartesian. Euclidean means "related to Euclid." Euclid was a… Continue reading Vocab Words: Euclidean and Cartesian
