|
<p>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.
|
|
<p>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.</p>
|
|
|
|
<p>Survex (including the graphical software 'aven') is already installed
|
|
on the expo laptop. These instructions assume that you are using the expo laptop.
|
|
|
|
|
|
|
|
<h3>Where to put your data</h3>
|
|
<p style="margin:4%">[These instructions pre-date the online form and describe typing using a text editor. Use the online form! But the content of the survex file is the same. This page will be edited to specifically describe using the form when time permits.]
|
|
|
|
<p>Where to put your data: <b>If in doubt, ask!</b>. These instructions assume
|
|
that you are typing it in on the <em>expo laptop</em>. (You can do it fom your own
|
|
laptop if you have been initiated into the deep magic of the ":loser:" repository
|
|
of the distributed version control system - see the
|
|
<a href="../computing/repos.html">list of repositories</a>.
|
|
|
|
<ul><li>If it is a surface
|
|
survey, it goes in the :loser:/surface" directory;
|
|
<li>if it is a file of fixed points
|
|
(like GPS fixes, or map coordinates), it goes in the ":loser:/fixedpts" directory;
|
|
<li>if
|
|
it is a new cave on the near-plateau, put it in a new directory under ":loser:/caves-1623".
|
|
<li>Underground data for Steinbrückenhöhle goes in one of the
|
|
subdirectories under :loser:/caves-1623/204/; it may well be clear which one from what it
|
|
links to, but if not, ask.</p>
|
|
</li>
|
|
</ul>
|
|
|
|
<h3>Use a template</h3>
|
|
|
|
|
|
<p>The beginner should start from the existing template file :loser:/template/template.svx
|
|
as this has lines to remind you to add various details - make sure you
|
|
don't leave any blanks! Copy <em>and rename this</em> to where you want to put your data
|
|
<em>before</em> editing it. Too many people have overwritten the
|
|
template in the past, try not to do this yourself.
|
|
<p>Working by editing a .svx file from another bit of the same cave may seem like a short cut but whoever edited it may have deleted some of the helpful and useful hints that are in the template.svx file - so don't do this please, until you really know what you are doing.
|
|
|
|
<h3><a id="filenames">Filename and data-entry conventions in svx files</a></h3>
|
|
|
|
<ul>
|
|
<li>Use Unix line endings (i.e. \n not \r\n).
|
|
|
|
<li>Use UTF-8 character encoding.
|
|
<li>NO UMLAUTS. Use <em>&uml;</em> for u-umlaut and <em>&oml;</em> for o-umlaut in text. But don't use these
|
|
in filenames.
|
|
|
|
<li>Cave numbers are written without any leading zeros at all (in filenames,
|
|
survey names, or anything else!).
|
|
|
|
<li>Entrances have station names such as <b>p204b</b>. In the event of the tag
|
|
location being different from the entrance location, the tag point
|
|
should be named with a "t" instead, e.g. <b>t204b</b>.
|
|
|
|
<li>No full stop (.) characters in station names.
|
|
|
|
<li>All filenames to be in lower case. Capital letters in filenames can still (in 2022)
|
|
cause hassle when moving between Linux and Windows. (This includes suffix letters for cave entrances: it is "87a" NOT "87A".)
|
|
|
|
<li>No filenames starting with "-" or "!".
|
|
|
|
<li>No colons in filenames.
|
|
|
|
<li>Caves with a provisional number consisting of a year and a serial number
|
|
should be <em>hyphenated</em>, thus 2018-ad-01 not with underscore 2018<b>_</b>01 or any of the various other
|
|
variants.
|
|
</ul>
|
|
|
|
|
|
|
|
<h3>The name of your survey</h3>
|
|
What to call your survey: all your data should be inside a begin/end pair
|
|
with a meaningful name. This need not be the same name as the file, but as a
|
|
general rule it should be so unless there is a really good reason not to. On
|
|
the other hand, if you have made two or three trips to the same cave,
|
|
it can be a good idea to nest surveys in one file:
|
|
<pre><i>File 2050-01.svx</i>
|
|
*begin 2050-01
|
|
*export pt1.1 pt2.5 [...]
|
|
*begin pt1
|
|
<i>[survey data from first trip]</i>
|
|
*end pt1
|
|
*begin pt2
|
|
<i>[survey data from second trip]</i>
|
|
*end pt2
|
|
*end 2050-01
|
|
</pre>
|
|
or you can create several .svx files.
|
|
Creating several .svx files seems to be current practice as it
|
|
simplifies the manual process of knitting several different people's trips together (though the online wallet system can only record one of these at the moment).
|
|
|
|
<p>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.</p></li>
|
|
|
|
<h3 id="stationanmes">Station names</h3>
|
|
|
|
<p>Every station should have a number <em>within your survey</em> even if it
|
|
is an existing station to which you have connected. Any survey stations which
|
|
you think can reliably be found again should be listed at the start of your
|
|
survey file. This includes the name (within your survey) of any existing points
|
|
you linked into. I have used lines like <tt>;*export mysurvey.pt1.0 ; 2nd bolt at
|
|
head of new pitch</tt> – this may or may not catch on as a standard.</li>
|
|
</ul>
|
|
|
|
<p>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 <tt>*equate</tt> and <tt>*export</tt> 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 <a href="#concrete">from
|
|
here</a>.</p>
|
|
|
|
<h3 id="plumbing">Plumbing your survey into the rest of the cave</h3>
|
|
|
|
<p>However, if you need to see your survey in relation to the rest of the
|
|
dataset:</p>
|
|
|
|
<ul>
|
|
|
|
<li>Don't put any *equate directives to other surveys into your file (or any
|
|
survey legs which quote station names from other survey files). Instead, go to
|
|
the file which *includes the other files in the same area. <br /><br />
|
|
For example, if you
|
|
have created a file trivial.svx in the caves-1623/204/deepsouth directory, go to the
|
|
file deepsouth/deepsouth.svx, where you will find *include lines for each of
|
|
the files, together with the *equate lines to connect them together. Add an
|
|
include for your file, and *equate lines for each of your survey stations which
|
|
is the same as one in another survey. If your survey connects to points in
|
|
surveys in files in more than one directory then the *equates should go in the
|
|
/204/204.svx file, but at this stage it is probably worth enlisting the help of
|
|
someone who knows the structure of the data inside-out! <br /><br />
|
|
<li>You should now find that if you run survex on one of the master files
|
|
(
|
|
<a href="/survexfile/1623-and-1626-no-schoenberg-hs">1623-and-1626-no-schoenberg-hs.svx</a>,
|
|
<a href="/survexfile/204">204.svx</a>,
|
|
<a href="/survexfile/smk-system">smk-system.svx</a>
|
|
, etc.) which includes the area of
|
|
your new survey, it is linked in and will show up when you use the resultant
|
|
.3d file in aven. </li>
|
|
</ul>
|
|
|
|
<p>Now you have been typing this on the expo laptop, and before you let someone
|
|
else use the laptop you need to find a nerd to do the deep magic to add your
|
|
file to the version control <a href="../computing/repos.html">repository</a> "loser". Watching the nerd do this is
|
|
usually your first initiation into learning how to do it yourself.
|
|
|
|
|
|
<h3 id="concrete">Example svx file</h3>
|
|
|
|
<p>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: (note we don't use umlauts)</p>

<p>That lot would be typed by copying :loser:/template/template.svx to

<p>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.</p>

<h3 id="postprocess">Postprocessing and Update</h3>
|
|
<p>Once you have your data typed in and checked, it must be run through the
|
|
survey software (which on expo will be <a
|
|
href="http://www.survex.com/">survex</a>) 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.</p>
