European Terrestrial Reference System 1989 (ETRS89)

The European Terrestrial Reference System 1989 (ETRS89) is a standardized framework for precisely locating points on Earth's surface across Europe. It provides a consistent coordinate system, similar to a universal map grid, that accounts for Earth's shape and movement. ETRS89 is aligned with the Global Positioning System (GPS), ensuring accurate and reliable positioning for mapping, navigation, and land management. This system helps scientists, engineers, and policymakers work with spatial data consistently, supporting activities like urban planning, infrastructure development, and environmental monitoring across European countries.
