The Most Flexible Command & Data Entry Format Available...

Benchmark Survey Professional consists of several programs divided into many flexible routines, some of which are described below. 

Routines may be selected by either numeric command or via our unique popup menus, providing easy access to Benchmark Survey's functions.

Users may even customize the screen menus to suit their own operating preferences. Benchmark’s unique customization menu allows the user to set up the program to accept data and print results in accord with their own procedures. Benchmark will even allow the user to create “batch” files with a word processor.

Field Data Editor

Extensive Coordinate Geometry

Coordinate Transformation

This program will balance automatically, if desired, a closed loop traverse or a closed connecting traverse to the known starting and ending coordinates. Multiple observations may be entered and averaged. 

Elevation data may be entered at the same time as traverse data. Distances may be entered in meters or feet and may be adjusted by slope angles as well as temperature. 

Legs may be entered optionally as side shots, or held constant (so that no adjustment is made during balance). Curve selections include radius or tangent legs. Once entry is completed, the angular error and complete closure data is output by the system. 

Many options are available including automatic, manual, or no angle balance; compass rule, Crandall’s rule, least squares or no adjustment; list field data, angular and linear error trials. Any of these options may be mixed as desired, and several trial adjustments may be analyzed before the final output is selected and the computed final coordinate points output and stored for the traverse. 

An outstanding feature allows random numbering of coordinate points to better accommodate field book notes. Traverse legs may be inserted or deleted if input errors are discovered after the original data entry is completed. Also, input data may be stored on the job disks for later use.

This program offers the most flexible coordinate geometry package available. The program accesses the randomly stored coordinates that were either entered by the operator or previously computed and stored. Traverse by bearing, azimuth or turned angle. Distances can be adjusted for slope angle, temperature, and/or converted from meters to feet. 

Side shots and 90 degree offsets may be calculated; you can inverse or traverse through a curve, solve for all four intersection types and use the radial stakeout routine to print angle and distance from a set-up point to any other point or group of points. Also included are a fill set of elevation reduction routines.

Coordinate Transformation

Benchmark Survey Professional will perform a transformation or rotation from one coordinate system to another. Newly computed coordinates may replace the previous ones, or be stored in a new location within the job. The angle of rotation may be entered or defined by entering two coordinates in each system. Reduction to sea level and scaling are also included. Individual points or groups of points may be specified.
