ABSTRACT:
A survey system including a survey instrument operable to receive signals indicating the Easting, Northing and elevation of a surveyed point. The survey instrument transmits data regarding the surveyed point coordinates to a radio terminal mounted on the survey instrument and having a command keyboard associated therewith. The radio terminal is operable to communicate with a base radio and controller connected to a digital computer which stores survey data for a predetermined number of survey points and is capable of performing calculations of at least elevations of points disposed intermediate a set of coordinates on a survey grid and calculating hole depth for blastholes based on the elevation of a surveyed point on the surface of material from which the hole is to be drilled. The base radio and controller are operable to communicate with plural survey instrument and radio terminal units. The system allows the use of field survey instruments without requiring the placement of the central processing unit and its databases in the field. Relay radio transceivers or modems may be interposed between the controller and the central processing unit. The system may utilize an asynchronous PC type central processing unit in conjunction with commercially available electronic survey instruments.
