  skos:definition """The National Mapping Program of the U.S. Geological Survey (USGS) is the
descendent of the Corps of Topographical Engineers, formed in 1838. The USGS
took over responsibility for mapping the country in 1879 and has been the
primary civilian mapping agency of the United States ever since. 

The most common and used USGS maps are the 1:24,000-scale topographic maps,
also known as 7.5-minute quadrangles. More than 55,000 7.5-minute maps were
made to cover the 48 conterminous States. This is the only in detail map series
that covers the entire area of the United States in a considerable amount of
detail. The National Map provides public access to consistent, high quality,
geospatial data and information from multiple partners to help inform decision
making by resource managers and the public.
