The notes (all of them, including dates, personnel, calibration, LRUD, -station details, etc.) should be copied onto a fresh page of the Survey Book +station details, etc.) should be filed away in a numbered wallet in the current +surveys file. You might have to include a transcription if they are illegible +(to other people; if you can't read them yourself, go back and do the survey +again!). Even if you do this, never throw away the original notes.
+ +The data should be typed into whichever computer is being used for the survey, again including all the notes, including station details and passage names (and make a backup copy to a floppy or another machine). It is absolutely essential that you also fill in details of which survey -book the notes are in, with page numbers. - -
Survex has its own documentation for the format of the data, though the template file and a look at someone else's data will quickly make this fairly clear. Survex has some very flexible data entry options, so there are a few extra guidelines to try to get some consistency in the way -everyone uses it within this project. +everyone uses it within this project.
The KH data is split into areas in directories "136" (all of 136 and the -Forbidden Land), "Chile" (everything from the start of 1999), "France" (all -the vertical France stuff, and flat France up to approx French Revolution), -"LHR" (all the left hand routes, and Ambidextrous), "North" (everything from -Carrefour north, including Siberia), "PHumour" (all Puerile Humour, Iceland -etc.), "RHR" (all the right hand routes, and through Knossos to Carrefour), -"Top" (just stuff near 161a entrance) and "Triassic" (Triassic Park and all -its side leads except Puerile Humour). If you really aren't sure where your -data should go, there is nothing to stop you using a "New" directory. +
Where to put your data: If in doubt, ASK! If it is a surface +survey, it goes in the "surface" directory; if it is a file of fixed points +(like GPS fixes, or map coordinates), it goes in the "fixedpts" directory; if +it is a new cave on the plateau, put it in a new directory under "caves". +Underground data for Steinbrückenhöhle goes in one of the +subdirectories under caves/204; it may well be clear which one from what it +links to, but if not, ask.
There is a complete index to all the existing surveys, which should enable you to find the data for any survey station, once you know its name. It's a fair bet that if your survey connects to a -station in one directory, your survey data should go in that same directory. +station in one directory, your survey data should go in that same directory.

There is no restriction on the length of these names, but as they can be +displayed in Aven, Tunnel and other such programs, it helps not to have +anything too elaborate. Older versions of Survex required each prefix to be +unique in its first eight characters, and this is not a bad guideline to +follow.
At this stage, you have done enough to get a centre line for drawing up. -If you aren't completely confident about the structure of the Austria -data, it may be best not to try to link your survey to everything else -so skip the next bit and read on from here. +If you aren't completely confident about the structure of the Austria data, or +the Survex syntax of *equate and *export which can be rather +cryptic for the uninitiated, it may be best not to try to link your survey to +everything else so skip the next bit and read on from +here.
