No two surveyors work the same way. This is why Surveyor's Assistant provides a large number of user-definable set-up options. With little effort, you can customize Surveyor's Assistant to your work style.

In fact, each section of Surveyor's Assistant software has a set-up screen to create the best fit between the software and the user's needs. Among these are the selection of graphic formats, total stations and output formats.

The set-up screens give you control over many aspects of the functions provided by Surveyor's Assistant. You have a say even in how the graphics should be displayed. Once configured, the system will stay the same until you change the setup again.

Surveyor's Assistant works with all popular brands of total stations. Whether you own a Lietz, TOPCON, Pentax, another popular total station, or a mix and match of several different brands, you can use the same data collector for all of your jobs.

The information collected can be transferred to your PC-based software without the need for an additional data conversion software package. Surveyor's Assistant has built-in data transfer formats (SA, Plain ASCII, Lietz, WILD, WILDsoft and a user-defined format). Simply select the one that is compatible with your system.

 Major Features
Field Work
The field work section handles all field data entry. It has been designed for flexibility and efficiency in entering, collecting and storing data. For example, measurements can be entered manually, or automatically collected from a total station through the MC5's dual RS-232 ports. You can also select 2D or 3D data collection.

Furthermore, the rod height, code data, and/or field description data may be set up to carry over from the previous point into the next point to eliminate redundant entry of data. Extensive options available for field data collection provide you with a system that will match your way of collecting data.

The field work section offers the following options for data collection:

  • Instrument condition settings (collimation error, EDM and prism offset)
  • Environment correction settings (temperature and pressure, with measurement units)
  • Units and system of measurement settings (distance unit, angle unit, azimuth system, angle direction, vertical system)
  • Instrument point number, height, code, description, and automatic time-stamp
  • Backsight point number, horizontal reading and optional height, vertical and distance measurements
  • Foresight point number, height, code description, horizontal angle, vertical angle and distance
  • Optional field notes

As data is collected, coordinates are computed automatically for instant graphing. Coordinate data recorded includes the following:

  • Point number, northing and easting, optional elevation
  • Optional point description
  • Optional point code
  • Control point indicator
Surveyor's Assistant provides you with three closure methods: Compass, Transit and Least Squares. It allows you to perform data reduction on-site and verify closure before returning to the office. Surveyor's Assistant also offers graphical proof of closure that puts an end to all the guess work that you will find with many other data collectors on the market.
Coordinate Geometry
Data collected during field work is both stored as raw data and converted into coordinates that are stored in coordinate files. Using the coordinate information, Surveyor's Assistant can quickly calculate and solve most common land-surveying coordinate problems typically reserved for the PC. You can get immediate results right in the field.

Surveyor's Assistant has more diversified and powerful Coordinate Geometry functions than any other field data collection package available. In addition, it provides instant graphic displays that give you solid visual evidence of the solution. This would not be possible if mere numbers were displayed.

The Coordinate Geometry section of Surveyor's Assistant offers the following functions:

  • Traverse
  • Inverse
  • Intersection
  • Curves and points, both symmetric and non-symmetric (horizontal, vertical, and spiral)
  • 2-point 2D & 3D resections
  • Translations, rotations, and scaling
  • Area calculation with hinge point cut and bearing cut options
Surveyor's Assistant provides you with the means to import coordinate data into your field data collector through it's stakeout functions. Not only can you do point staking, but you can also perform offset and slope staking.

Like the FIELD WORK operations, STAKEOUT is a streamlined procedure. You may define the acceptable tolerance in order to properly stake the job. Once a range of points to stake is established, the Surveyor's Assistant works interactively with the instrument to assist you in pointing to the target. The STAKEOUT function provides you with the distance "long or short" and "left or right" from the expected point as well as a "cut and fill" measurement. When the target is within the user-specified tolerance, tones are sounded to alert you to a successful sighting. Data is recorded to provide either the actual stake position, or the offset and cut/fill from the computed position.

You can print to a printer or a file in various formats and units. Using Surveyor's Assistant, data can be printed directly from the hand-held. With the use of the portable MC-PRINTER, you can even produce a hard copy right in the field.
Surveyor's Assistant has a powerful graphics generator that allows you to see exactly what you just surveyed. The beauty of these graphics is that from any point within the software, you have the capability to plot the latest data collected, coordinate geometry solution, and adjustment solutions directly to the screen.

The data collected can also be plotted on an HP-GL or DM/PL plotter. Plots may be annotated with various combinations of symbols, point numbers, coordinates, elevations, codes or descriptions.

A number of setup options are provided to control the plot output. In addition, you may specify the range of data to plot.

 Unique Features
Surveyor's Assistant has some unique features that set it apart from other data collectors. A few of these features are described in some detail below.
Pop-up calculator
The Pop-up Calculator is a full-screen scientific RPN calculator that pops up at the press of a key. It is available throughout the software at any time you need calculations performed. This calculator features a 4-level stack, a 10-register memory and over 50 functions including:
  • Trigonometry functions that work in degrees-minutes-seconds as well as radians or decimal degrees
  • Logarithmic functions
  • Unit conversions (including feet to feet-inches-sixteenths)
  • Statistical functions
  • Memory register and stack functions

You can use the calculator to do miscellaneous calculations, or you can use it interactively with Surveyor's Assistant. The pop-up calculator can take data from the current data field in Surveyor's Assistant, perform an operation on it and return the result to the data field.

Predefined Codes
Surveyor's Assistant permits the use of codes to identify points. You can set up a table of predefined code names that can be automatically incorporated into the point description.
In many cases, when working with a large number of points, you will want to perform several functions on a subset of the total job. The FIGURES option in Surveyor's Assistant allows you to do this without redundant numerical entry. You can define a figure from a sequence of points and connect them with lines and/or curves. Such figures can be used by the stakeout, graphing, and plotting routines as well as COGO area, scale, rotation and translation routines. When graphing or plotting, multiple figures can be defined and used with a job. The use of figures greatly simplifies working with large jobs and tremendously increases your productivity.
