6 天之前 · Topography Data Access and Tools NASA data detail topography across the land surface, ocean, cryosphere, terrestrial hydrosphere and within the context of climate change. Our datasets and tools help researchers translate these interconnected data …

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.

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.

Our objective is to provide the scientific and civil communities with a state-of-the-art global digital elevation model (DEM) derived from a combination of Shuttle Radar Topography Mission processing improvements, elevation control, void-filling and merging with data unavailable at the time of the original SRTM production:

2021年3月1日 · NASA Shuttle Radar Topography Mission V3 Global 1 arc second hillshade image of the Mt Everest region The Land Processes Distributed Active Archive Center ( LP DAAC ) recently released additional tiles in NASA's Shuttle Radar Topography Mission (SRTM) Version 3.0 Global 1 arc second dataset (SRTMGL1), to include coverage over Asia and Australia.

6 天之前 · NASA's DEM data such as files collected by the Space Shuttle Radar Topography Mission (SRTM), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), and Global Ecosystem Dynamics Investigation (GEDI) and other instruments are useful for a range of land research from predicting wildfire behavior to mapping terrain elevation for ...

2024年8月14日 · After years of pre-launch preparation and 18 months of post-launch effort, all science data products from the Surface Water and Ocean Topography mission are fully validated.

The Airborne Topographic Mapper (ATM) measures topography to an accuracy of ten to twenty centimeters by combining measurements from an airborne laser altimeter and GPS (Global Positioning System) receivers. The ATM has demonstrated this accuracy at distances as great as 1000 kilometers from any base station.
