Records & Research




The St. Louis County Surveyor’s office maintains and archives a large volume of records pertaining to land surveying.  We have established a system of indexing and scanning these records to make them available for private land surveyors and property owners.  Research can be conducted on-line or at one of our public research terminals located in our Virginia and Pike Lake offices.


Survey Explorer

The Survey Explorer is a web map application designed to access a large number of the survey record resources housed in the County Surveyor’s Master Index(CSMI) and available in the offices of the County Surveyor. Below are links to the Survey Explorer application, Guide, and a static PDF of the CSMI.
