The European Vertical Reference System (EVRS) is a standardized framework used to measure elevation across Europe. It provides a consistent way to reference heights above sea level, ensuring that data from different countries can be compared accurately. The system is essential for various applications, including mapping, construction, and environmental monitoring. Developed by the European Commission and supported by European countries, the EVRS helps to unify the diverse vertical reference systems previously used. By establishing a common reference point, it enhances collaboration in scientific research and infrastructure projects, promoting better planning and management of resources across the continent.
