USGS

The United States Geological Survey (USGS) is a leading scientific agency of the U.S. government that provides reliable information about the Earth's natural systems. Established in 1879, the USGS conducts research on geology, geography, biology, water resources, ecosystems, and environmental change. It monitors natural hazards such as earthquakes, volcanoes, floods, landslides, droughts, and wildfires, helping communities prepare for and reduce disaster risks. The agency also collects and maintains extensive datasets on topography, land use, climate, minerals, and water resources. Through advanced mapping technologies, satellite imagery, and remote sensing, the USGS produces accurate geospatial data used in scientific research, environmental management, infrastructure planning, and public safety. Its open-access data, maps, and publications are widely utilized by government agencies, researchers, educators, engineers, and GIS professionals to support informed decision-making, resource conservation, and sustainable development worldwide.
