The National Spatial Reference System (NSRS), which is managed by the National Geodetic Survey (NGS), is a coordinate system that includes latitude, longitude, elevation and other values. The NSRS consists of a National Shoreline, the National CORS (a system of Global Positioning System Continuously Operating Reference Stations), a network of permanently marked points and a set of models that describe dynamic geophysical processes affecting spatial measurements.[1]
