Spatial Reference System

A Spatial Reference System (SRS) provides a framework to accurately locate and describe geographic data on Earth's surface. It defines how coordinates (like latitude and longitude) are mapped to real-world positions, ensuring consistency across maps and spatial datasets. Think of it like a universal language that allows different maps, GPS devices, and geographic information systems to share and compare location information precisely. Without an SRS, spatial data couldn't be reliably aligned or integrated, making it essential for navigation, urban planning, environmental monitoring, and many other applications.
