Horizontal and Vertical Control Index  

This search tool allows you to find the horizontal and vertical control stations established by the Missouri Department of Natural Resources (MO GRS), the National Geodetic Survey (NGS), and the United States Coast and Geodetic Survey (USCandGS). 

The horizontal and vertical control stations are indexed by township and range in each county.  The Horizontal and Vertical Control Index contains approximately 13,000 entries. You may order the state wide Horizontal and Vertical Control Index and data sheets on CD-ROM or order specific data sheets for one or more horizontal and vertical control stations by using the Land Survey Program online order form.  If you are looking for information not contained in the search results, you may contact us at the phone number listed below.

Please contact the Land Survey Program for the most current information and questions about mark maintenance or newly established stations.
