CRSD (Coordinate Reference System Database)

A Coordinate Reference System Database (CRSD) is a digital collection that stores information about different ways to locate places on the Earth's surface. It contains data about coordinate systems, projections, and datums, which help mapmakers and GIS software accurately translate real-world locations into digital maps. Think of it as a comprehensive reference library that ensures spatial data aligns correctly across various mapping systems, making geographic information consistent and reliable for analysis, planning, and navigation.
