Preface
Introduction
12dModel is an interactive graphics program designed to process survey data, quickly build terrain,
conceptual and detail design models.
Data is easily read in, triangulated and contoured to build an initial terrain model. Roads, platforms,
channels or other design features can be added interactively and a merged model containing the initial
terrain and the new design features formed to produce conceptual design models.
All Models can be examined in plan, section or perspective views. The number and type of views
displayed on the screen is totally user defined.
By using a mouse and flexible on-screen menus, 12dModel is easy to use and requires a minimum of
training.
The 12d Model Reference manual is available as on-line help and has information all panels and menus in
12d Model.
However, because Microsoft’s Help system only allows individual topics to be printed, the entire
12dModel Reference manual has also been supplied as a PDF file. The PDF file can be used to print out
large sections of the manual. Adobe’s PDF format can be read by Adobe Acrobat or the free Acrobat
Reader
Also, the Survey Appendices from the 12dModel Reference manual have also been supplied as a separate
PDF file.
This document is the Survey Appendices from the 12d Model Reference manual.

A 12D Survey Guide
The information contained in this appendix outlines the general options, terminology,
definitions and methods used by 12dModel for the purpose of the input, reduction and output
of survey information. It is a general guide, with the appendices following relating to specific
instruments and the interactions with 12dModel.
Guide to Survey Reduction in 12d Model
The 12d Model survey options are used to reduce electronically recorded survey information and
produce 12dModel strings, a process called survey reduction.
In the most general case, there are three steps involved:
1. 12dModel downloads raw data from a data collector and stores it on the computer.
2. The raw data file is converted to a standard 12dModel raw field file format, normally with
extension of “.fld”. For simplicity, the standard 12dModel raw field file is called the "12d
field file".
3. The 12d field file is read into a 12d Model Survey Reduction function (12d Survey function)
and reduced. If errors occur, the field data for 12d Survey function can be interactively and/
or graphically edited. The reduction produces 12dModel super strings in one or many 12d
Model models.
In some circumstances, not all steps are necessary.
For example, Step 1 is not necessary when the raw data file is already on the computer (and
hence doesn’t need downloading).
This often occurs when data collectors have PCMCIA cards and PCMCIA card readers on the
computer. Another example is when the raw data file has already been downloaded to the
computer using another package such as HyperTerminal. Or maybe the raw data file has already
been downloaded in a previous 12dModel session.
Steps 1 and 2 are not necessary when the data is already in the form of a 12d field file.
This occurs when other software packages, such as TP Setout, can produce a 12d field file. Or the
12d field file was created in a previous 12dModel session, maybe even on a different computer.
A data flow diagram for the survey reduction process is:
