What is USGS?
According to GIS, the United States Geological Survey (USGS) is a U.S. government scientific organization that is essential to the gathering, processing, and sharing of geographic and spatial data. Numerous geospatial datasets, such as topographic maps, aerial images, elevation models, hydrographic data, geology maps, and land cover classifications, are produced and maintained by the USGS, which is well known for this.
GIS applications in domains like scientific research, natural resource management, land-use planning, environmental monitoring, and disaster response rely heavily on USGS data. It is a vital tool for GIS academics and professionals since it offers free access to geospatial data via sites like EarthExplorer, The National Map, and Landsat imaging services.
