Automated mapping software that translates the alphanumeric data associated with a survey (distances, bearings, coordinates, etc.) into digital map information for creating and updating a digital cartographic data base.
A computerized surveying - plotting calculation methodology created at MIT in the 1950's. Positions are measured relative to a given base position by distance and azimuth, rather than an absolute coordinate.
This refers to a data conversion process in which a digital map is constructed from written descriptions, such as legal descriptions of land parcel boundaries. These descriptions often contain information about line length and direction, and point locations, all relative to the locations of certain key features such as geodetic control points, survey monuments, previously COGOed survey lines, etc.
