This document provides an overview of datums, coordinate systems, and map projections. It discusses transforming real world locations to maps, including potential distortions, and establishes international and GIS-specific coordinate reference systems. The goal is to help understand how to represent global locations on flat paper maps or computer screens by addressing common questions around the "best" projections to use and how real world references are translated to digital coordinates.
