The first version was written during the 1990 Expo in Austria in the old potato hut.
A < a href = "../survexhistory96.htm" > history of survex< / a > article was published in Cambridge Underground 1996. It covers the period 1988-1996.

< p > You will discover that the application installed is actually called "aven" but do not be concerned.
This is what you will use to visualise .svx files as beautiful cave centre-line surveys.

TopoDroid is an Open Source Android app to make cave surveys with the DistoX.
< p >
Features:
< pre >
* communication with the DistoX device(s),
* support A3 and X310 DistoX * data stored in a SQLite DB.
* surveys management: stations entry, notes and comments.
* exported survey formats: Therion, Compass, Survex, VisualTopo, DXF, csv.
* imported survey formats: Therion.
* sketch drawing, Therion-wise with points (symbols), lines and areas. Saved as th2 files, PNG images, and DXF files.
* user-defined drawing symbols.
* save whole survey as ZIP archive, and restore from it.
* 3D display (using Cave3D). * photoes and GPS localization (using GPSaverage).
* internal sensors measures and external measures. * DistoX calibration.

The goal is to model Cave systems in 3d and have a high degree
of interaction between the user and the information.

My task was to write a new program which could read the data from an external file,
ideally one which resembled a .svx file as much as possible.
Psurvex supports
only a subset of the .svx file format but the same file should process in Survex
without any problems. You need to write a .svx file and save it somewhere on your machine.
This program will then process the file and create a second file containing a list of
points for plotting on graph paper and some statistics about your survey.
