The main objective of the Shuttle Radar Topography Mission (SRTM) was to map the Earth’s surface to create detailed digital elevation models. This mission, which took place in February 2000, used radar interferometry to gather data on the topography of the Earth. The information collected was instrumental in producing high-resolution elevation data for a significant portion of the planet, helping to improve geographic information systems and further research in various fields such as geology, hydrology, and urban planning.
The creation of digital elevation models from the SRTM data allows for a range of applications, including landscape analysis, terrain modeling, and the assessment of natural hazards. The SRTM's contributions significantly enhanced our understanding of Earth's physical features and facilitated advancements in geographic research and spatial data analysis.
