Enter the coordinate values on the appropriate text boxes and select angle display format that relevant to input values, then clickto compute the distance. These markers were used to identify important topographical features, and to serve as control points in manual surveying to measure elevation; this particular marker (first pic below) is a triangulation marker that was used for that . Non-Operational Sites are not expected to provide data (no data last 30 days) Survey markers, also called survey marks, survey monuments, or geodetic marks, are objects placed to mark key survey points on the Earth's surface. In the 19th century, these marks were often drill holes in rock ledges, crosses or triangles chiselled in rock, or copper or brass bolts sunk into bedrock. The mathematical models for the Earth and physical influences affecting our measurements are used in . Survey markers were often placed as part of triangulation surveys, measurement efforts that moved systematically across states or regions, establishing the angles and distances between various points. MnDOT's Geodetic Monument Viewer Application is an interactive web tool that allows users to display geodetic survey control by datum and adjustment categories, as well as link to the data sheets which contain coordinate details.
