Shuttle Radar Topography Mission (SRTM)

The Shuttle Radar Topography Mission (SRTM) was a project that used radar technology on a space shuttle to create detailed, three-dimensional maps of Earth's surface. It collected elevation data by sending radio waves to the ground and measuring the returned signals, capturing the shape of mountains, valleys, and plains worldwide. Launched in 2000, it provided high-resolution terrain information that helps in geographic analysis, climate studies, and infrastructure planning. SRTM's data has greatly advanced our understanding of Earth's topography with global coverage and accuracy.
