Coordinate Reference System
A Coordinate Reference System (CRS) is a framework used to define how locations on Earth are identified and mapped. It consists of a set of rules and reference points that determine how to translate real-world locations into numerical coordinates, like latitude and longitude. This system allows us to accurately place features on maps and understand their positions relative to one another. Different CRSs exist for various purposes, ensuring that data from different sources can be used together effectively. In essence, a CRS helps us navigate and interpret the geography of our world.

A Coordinate Reference System (CRS) is a way of identifying locations on Earth using a set of numbers, much like using an address to find a house. It defines how geographical data is mapped and understood, allowing us to pinpoint places accurately. Common examples include latitude and longitude, which use degrees to indicate positions globally, and projected systems like UTM, which represent areas on a flat map. By using a CRS, we can consistently share and interpret spatial information across different tools and applications, ensuring everyone understands the locations being referenced.
