Disclosed is an automated surveying system composed of three separate stations. Two base line stations are positioned at selected points on the terrain and the distance between them measured. A third station is positioned at successive remote points on the terrain, removed from the base line stations, and topographic and contour data are collected for each successive remote location of the third station by measuring the distance between each of the stations, the difference in elevation between each of the stations, and the bearing of the remote station relative to the base line stations. Each of the base line stations contains distance measuring equipment and apparatus for measuring both elevational and horizontal angles. Data collected by two of the stations are transmitted to a main one of base line stations which contains data processing equipment to convert the data to a map of the terrain as the survey data are collected.
