Elevation Finder - Topographic map - Altitude map - MAPLOGS
Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.
Terrain Elevation | NASA Earthdata
NASA provides terrain elevation measurements from aerial and satellite instruments that can be ideal for creating DEMs, analyzing the effects of landslides and floods, assessing ice sheet thickness, improving topographical maps, and many more applications.
Is ground elevation the same as altitude? - NCESC

What is the most accurate way to measure elevation?
2024年6月19日 · There are two primary ways to measure the elevation of a point above sea level: using an altimeter and using a digital elevation model. An altimeter is an instrument that measures the elevation of a point using atmospheric pressure as an indication of height.
