What is OpenAltimetry?
NASA’s OpenAltimetry (OA) is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from ICESat-2 and ICESat satellite mission altimetry data. With OA, users can use explore how different types of surface heights have changed across the Earth over time, and all you need is a web browser.
