HAVOC
The Department of Lands has used computer programs for the least squares adjustment of geodetic survey observations since 1961. HAVOC (Horizontal Adjustment by Variation Of Coordinates) was first compiled in 1972 and although developed primarily for in-house use, HAVOC has been widely distributed amongst the Australian survey industry.
Some important features of this software are:
- 2-dimensional adjustment only
- all input / output data are text files
- handles 8000 observations and 1000 stations
- numerous observation types available
- computes provisional and adjusted MGA coordinates
- provides full statistical analysis (error ellipses etc)
- computes rigorous scale factors and geodetic corrections automatically
- applies geoid (ausgeoid98) corrections where required
The current version 3.6 (4/04/2008) is available to download as an executable program (EXE 497 kb) only. To run in Windows, use a Command Prompt.
The documentation (PDF 345 kb) is also required to assist with data formats and use of the many options available.
Sample data files (ZIP 8 kb) are provided to illustrate formats for various observation types.
Please note, that whilst all effort is made to ensure the accuracy and currency of this application, Lands does not accept responsibility for any actions arising from its use.
