USGS EROS Archive - Digital Elevation - Shuttle Radar Topography Mission (SRTM)

The SRTM 1 Arc-Second Global dataset provides high-resolution elevation data at a spatial resolution of 30 meters, covering 80% of the Earth's land surface between 60°N and 56°S. The data was collected in February 2000 during the Shuttle Radar Topography Mission (SRTM) using radar technology aboard the space shuttle Endeavour. It includes void-filled elevation models processed to address gaps and anomalies. The dataset is available in multiple formats, such as GeoTIFF and DTED®, and is widely used for GIS applications like terrain analysis, hydrology, and urban planning. The data is referenced to the WGS84 horizontal and EGM96 vertical datums. Digital Elevation Models (DEMs) are used to generate elevation and slope metrics which can be used for analysis of climate induced natural hazard like landslides
