SRTM | NASA Earthdata
2000年2月11日 · The Shuttle Radar Topography Mission (SRTM) payload flew aboard the Space Shuttle Endeavour during the STS-99 mission. SRTM collected topographic data over nearly 80% of Earth's land surfaces, creating the first-ever near-global dataset of land elevations.
Glacier Topography/Ice Sheet Topography | NASA Earthdata
6 天之前 · Surface relief of the land. Topography usually is measured in meters above sea level. The topography can be very different from one location to another. Topography can be flat, or mountainous, or hilly.

NASA's Surface Water and Ocean Topography (SWOT) Mission
2024年4月25日 · On December 16, 2022, the Surface Water and Ocean Topography satellite flew into space aboard a SpaceX Falcon 9 rocket from California's Vandenberg Air Force Base.
Hydrocron: A New Tool for SWOT Time Series Analysis
2024年8月27日 · The Surface Water and Ocean Topography satellite collects data on the global ocean and the major water bodies that comprise Earth's freshwater resources. Over time, these data will make it easier for researchers to analyze how waterbodies are responding to climate change and the impacts of human activity on Earth's freshwater systems.
SWODLR Integrated into Earthdata Search
2024年10月9日 · The SWOT On-Demand Level 2 Raster Generation System (SWODLR) is an open-source software system developed to generate custom Level 2 raster data products from data acquired by the Surface Water and Ocean Topography platform.
Synthetic Aperture Radar (SAR) | NASA Earthdata
The angle between the direction the antenna is pointing and the nadir is the look angle. The angle between the radar beam center and the normal to the local topography is the incidence angle. Both angles are sometimes used synonymously, which is only valid if the SAR geometry is simplified to neglect Earth’s curvature and local topography.
