Elevation is a research area that focuses on the measurement and mapping of height above a reference point, typically sea level. This can be done using various methods such as GPS, satellite imagery, lidar, or traditional surveying techniques. Elevation data is important for a wide range of applications, including cartography, engineering, urban planning, natural resource management, and climate research. Researchers in the field of elevation work to improve the accuracy and resolution of elevation data, as well as develop better methods for incorporating it into models and analyses.
