Coordinate Reference Systems

A Coordinate Reference System (CRS) is a mathematical framework that locates points on the Earth's surface using coordinates, such as latitude and longitude or other grid systems. It provides a way to accurately describe positions, measure distances, and align maps. Different CRSs are designed for specific purposes or regions, ensuring consistency when working with geographic data. Think of it as different "map languages" that help mapmakers and GPS devices understand and communicate location information precisely.
