The Missouri Department of Natural Resources’ Division of Geology and Land Survey (DGLS) in US has delivered a number of significant maps and land surveys recently. These include official state boundaries between Missouri and Iowa, portions of Missouri and Arkansas, and the Tri-State intersection of Missouri, Kansas and Oklahoma. Boundaries between the Missouri counties of Platte and Buchanan, and St. Francis and Ste. Genevieve, were also included. These documents will be placed in the rare documents vault along with other fundamental Missouri documents, such as the Missouri Constitution, original land surveys, all bills passed by the state legislature and other foundational documents. Each of these documents are historically significant because they define the statutory location for the state and county boundaries.
The Land Survey Program develops and provides information required for the accurate and economical location of property boundaries throughout Missouri. Maintaining consistent and dependable land boundary information avoids boundary disputes and errors in land transfers. This often involves the reestablishment of old markers, referred to as monuments, originally established for the U.S. Public Land Survey System (USPLSS). These monuments locate the boundaries of land surveys dating as far back as the early 1800s. The use of GPS has enhanced the ability to locate and remark these monuments, thereby assuring their accuracy and permanence.
