Coordinate Reference System (CRS)

A Coordinate Reference System (CRS) is a framework that defines how geographic locations are represented on a map or globe. It provides a set of rules and a coordinate system—like latitude and longitude—that allows us to pinpoint, measure, and compare positions accurately across different maps and spatial data. Essentially, CRS ensures that spatial information from various sources aligns correctly, enabling consistent navigation, mapping, and analysis of geographic features on Earth's surface.
