<p><code>This is an attempt at a <em>complete set of optional software</em> for using survex, tunnel, therion, photos and GPS tracks to document our caves: using the existing data archive and processing new survey data.
<p>If you want to do software development instead, go to <ahref="../troggle/troglaptop.html">configuring a troggle development machine</a>.
<p></a>Long-standing Expo policy is to use open tools and protocols so we can retain control of our own data over the long term. And not to require expo-goers to sign up to external services or spend money on software.
So we use <ahref="https://en.wikipedia.org/wiki/Free_and_open-source_software">FOSS software</a>.
You can use other software on your own machine if it is format-compatible and exports data in the formats we want,
<li><ahref="https://github.com/CaveSurveying/tunnelx">Tunnel</a>: 2.5D cave drawing program based on Survex-compatible data which can also read PocketTopo files. (Generally called 'tunnel' even though the project and executable is actually 'tunnelx'.)
<li><ahref="https://sourceforge.net/projects/viking/">Viking</a> - an alternative to GPSprune. The <ahref="https://github.com/viking-gps/viking">code</a> is on github.
<li><ahref="https://vectr.com/user-guide/">Vectr svg</a> - quick and easy sketcher (browser-based, Chrome only) for making rigging topo diagrams: "free forever" committment, but not open source. Please export as svg not jpg or png.
<li><ahref="https://github.com/patrickbwarren/inkscape-survex-export">inkscape-survex</a> - Patrick's plugin to export a traced inkscape line drawing to a survex file.
<li><ahref="http://www.thomas-holder.de/projects/inkscape-speleo/extensions/">inkscape-speleo</a> - plugin to import/export survex, therion and pockettopo files to the drawing package inkscape.
<li><ahref="https://imagemagick.org/script/">Imagemagick convert</a> for re-scaling photographs and scanned images and converting from PDF to JPG. (NB you may need to fix this <ahref="https://stackoverflow.com/questions/52998331/imagemagick-security-policy-pdf-blocking-conversion">security issue</a>)
<p>Nearly all our Austrian surveys have beeen produced using Tunnel (or were hand-drawn) but many smaller caves and some areas of SMKsystem are done with Therion because Therion does elevations and Tunnel doesn't. Expo has a policy decision on which to use: if it is an entirely new disconnected cave, then use Therion. If it is a passage in a cave where previously we used Tunnel, then use Tunnel. See also <ahref="/expofiles/tunnelwiki/wiki/pages/Other_Cave_Software.html">Comparison of Tunnel to Other Cave Software</a>.</p>
<li><ahref="../../documents/tunnel-loefflerCP35-only.pdf">Introduction to using Tunnel</a> - article by Dave Loeffler. This is really good and should be read first.

<li><ahref="https://github.com/CaveSurveying/tunnelx">Tunnel - master copy since August 2019</a>. This is where the software is actively developed and is the most up to date copy, but the documentation is not as complete as in the other locations.

When we are drawing up the surveys after each expo we discuss things online here. Ask Wookey for an invitation.
