- 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
- Digital Elevation Terrain Model (DEM) | NASA Earthdata
NASA's data for digital elevation models (DEM) comes from airborne and space-based sources and are useful for analyzing a majority of Earth's terrain
- Air Mass Density | NASA Earthdata
Air mass density is a fundamental property of atmosphere Mixture of gases forming Earth's atmosphere, consisting of nitrogen (∼78%), oxygen (∼21%), water vapor, and other trace gases such as carbon dioxide, helium, argon, ozone, or various pollutants The concentration of water vapor is very variab
- How high would you need to be in order to see the curvature of the . . .
To see the curvature of the Earth, you would need to be at an altitude of at least 35,000 feet, which is roughly the cruising altitude of commercial airplanes
