Shuttle Radar Topography Mission (SRTM) | NASA Earthdata 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
Terrain Elevation - NASA Earthdata NASA's terrain elevation data measure current height and changes in land altitude and are useful for creating digital elevation models
What is the altitude of Austin? - Answers Density altitude is a measure of air density relative to standard atmospheric conditions, and it is calculated by adjusting the pressure altitude for temperature and humidity
What is the altitude of the International Space Station? The International Space Station (ISS) orbits Earth at an average altitude of approximately 420 kilometers (260 miles) above the Earth's surface This altitude allows the ISS to remain in a stable
OpenAltimetry | NASA Earthdata NASA’s OpenAltimetry is a free and powerful map-based data visualization and discovery tool for exploring surface elevation profiles from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and ICESat platform mission altimetry data With OpenAltimetry, users can explore how different types of surface heights have changed across Earth over time Please note that OpenAltimetry processes
Remote Sensing - NASA Earthdata What is Remote Sensing? Remote sensing is the acquiring of information from a distance NASA observes Earth and other planetary bodies via remote instruments on space-based platforms (e g , satellites or spacecraft) and on aircraft that detect and record reflected or emitted energy Remote instruments, which provide a global perspective and a wealth of data about Earth systems, enable data
On the Trail of Contrails | NASA Earthdata Lower altitude aircraft are not going to create them because the temperature is not low enough ” In very humid conditions, some aircraft may also produce wingtip vortices, or contrails that spiral out behind each wing Low-flying planes at airshows often generate what look like contrails, but are simply special effects created by smoke
