Tony Rooke entering data in days gone by
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.
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.
File 2050-01.svx
*begin 2050-01
*export pt1.1 pt2.5 [...]
*begin pt1
[survey data from first trip]
*end pt1
*begin pt2
[survey data from second trip]
*end pt2
*end 2050-01
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, 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.
However, if you need to see your survey in relation to the rest of the dataset:
To make that all a bit more concrete, here is a fictitious example of a survey off Swings & Roundabouts in 204. Let's say that you went to explore a lead from the QM list numbered 2002-99, that the nearest survey station was listed as 204.allswings.swings5.2 and you found it successfully, and numbered it within your own survey as station 0. Then you might create the following file:
File wibble.svx *begin wibble ; Locn: Totes Gebirge, Austria - Loser/Augst-Eck Plateau (kataster group 1623) ; Cave: Steinbruckenhöhle *title "Wibbled by Goesser" *date 2004.08.32 ;date the survey was done *team Insts John Doe *team Notes Jane Doe *team Tape Jane Doe ; ref.: 2004 #999 ; the #number is on the clear pocket containing the original notes. ; ====== stations refindable to link to other surveys: ====== *export 0 ; list all exported survey points. *calibrate tape 0 ; +ve if tape was too short, -ve if too long ;calibration data 148,+23,147,+23.5,148,+23,329,-23,328,-23.5,328.5,-23 ;from to tape compass clino ; remarks 1 p5 5.48 181 -27 [and the rest of your survey data] 6 5 5.66 - DOWN ;stn L R U D Desc ;1 0.7 0.4 0.3 0.5 RP top of boulder [and the rest of the station details] *end wibble
That lot would be typed by copying caves/204/template.svx to caves/204/swings/wibble.svx and then filling in the blanks and adding your data. If you are linking to the rest of the survey then in the file caves/204/swings/allswings.svx add the lines:
*include wibble *equate wibble.0 swings5.2
Remember not to put surface data and underground data in the same file, even if they are part of one continuous survey. You need to create two files, with a defined station for the entrance, and a suitable equate in the file which includes both surface stuff and underground stuff.
Once you have your data typed in and checked, it must be run through the survey software (which on expo will be Survex) and a centre line printed, both for plan and for extended elevation. Measure the print out to check that it really has printed at the scale you wanted (typically 1:500), as this has sometimes caused problems in the past.
