Geographic Reference System

The Missouri Geographic Reference System is a network of accurately positioned Horizontal and Vertical control monuments (latitude, longitude, elevation and state plane coordinates) used by land surveyors, engineers, cartographers and others who have a need to locate positions on, below or above the surface of the earth.

The Simple Map Viewer New! configuration for the Missouri Geographic Reference System (control points) is now in our production environment and available to the public.
