| LISDAT Product Information |
The LISDAT data collection and field computation system has been specifically
designed by LISTECH for the Corvallis MicroTechnology MC series of handheld
computers. The LISDAT software is a totally integrated field survey solution
that supports all well known brands and models of total station. The system can
collect a variety of observation types and includes manual data entry,
reduction of observations, full coordinate geometry calculations, design set
out, plotting, printing and data transfer to and from your office computer.
All this and more, combines to create the ideal portable collection and
computation system. To complete the total solution, IBM PC compatible companion
software is provided, to enable two way data transfer between your PC, and to
convert data files to and from popular computing systems including DXF, MOSS
and many others.

The CMT MC Series of hand held field computers are more than just data
collectors. Combined with the LISDAT software, all your field survey
requirements are integrated into one flexible system. Automatic data collection
of a variety of observation types, combined with manual data entry, reduction
of observations, computations, set out, plotting, printing and data transfer to
and from your office computer, give you the ultimate in portable computing
ability.
The LISDAT Software can be supplied with combinations of the following
options, or packaged together for an affordable total field solution.
| Option 1: Total Station Data Recording and Set Out |
|
|
Storage and access to multiple job/data files. Two way
communication allows minimal handling of the total station, apart from
pointing. Your total station is controlled by the LISDAT software.
Observation types:
Slope distance, horizontal and vertical angles.
Horizontal distance, height difference and horizontal angle.
Coordinates.
Latitudes and departures.
Angles only.
Stadia.
Distance measurement can be taken in coarse or fine mode.
Split observations (distance followed by azimuth).
Hidden point observations. (prism pole with two prisms)
Offset observations (left, right, forward, back, up or down).
Remote elevation observations.
Benchmark elevation transfer.
Backsight and station change checks for dX, dY & dZ.
Point coordination.
3 dimensional set out (with options for zero azimuth set out and to record set
out observations for comparison with design).
Key assignment of feature codes and fieldnotes eliminates time consuming key
punching.
Viewing, editing and delete facilities.
Data transfer to computer and/or printer via RS-232, including direct output to
Moss.
Control point coordinate file capability.
|
| Option 2: Coordinate Geometry Computations, Including
Manual Data Recording and Set Out. |
|
|
Point creation by:
Radiations and traversing.
Distance/distance intersection.
Azimuth/azimuth intersection.
Azimuth/distance intersection.
Chainage and offset.
Chord/arc distances.
Traverse adjustment (Crandel's, Bowditch and Transit).
Elevation adjustment.
Computations:
Radiation joins,
Traverse joins Chainage and offset.
Polygon area (including arcs).
Transformations:
Height shift
Rotation
Scaling
Translation
File merging.
Point coordinate editor.
Reverse polish notation (RPN) calculator.
|
| Option 3: Reduction and Plotting. |
|
Complete file reduction to coordinates.
Free station calculation. (3D resection)
Plotting of point crosses, numbers, heights, strings and grid.
Support for HP-GL, DM/PL, RD-GL, and Graphtec compatible plotters.
|
| Option 4: Sun Azimuth. |
