Contractor vertical accuracy checkpoints for 3D Elevation Program digital elevation models in the Northern Gulf of Mexico and Atlantic coastal regions, 2012–2020

Vertical accuracy of elevation data in coastal environments is critical because small variations in elevation can affect an area’s exposure to waves, tides, and...海岸环境中高程数据的垂直精度至关重要，因为高程的微小变化即可影响某一区域受海浪、潮汐及……侵袭的程度。
