<h1>Expo Survey Statistics</h1>
|
|
|
|
<p>{{ expoCount }} expeditions: {{ personCount }} people, {{ caveCount }} caves, {{ walletsCount }} wallets and {{ logbookEntryCount }} logbook entries.
|
|
|
|
<p>Number of survey legs: {{adduplegs}} <br />
|
|
Total length: {{adduplength}} km adding up the total for each year.</p>
|
|
|
|
<p>These lengths are not authoritative.
|
|
<p>These are <em>uncorrected</em> tape lengths.They are uncorrected
|
|
because they are lengths <em>before</em> any loop-closure corrections done by survex and because they <em>include duplicated surveys</em>. These numbers include pitches but exclude splays or surface-surveys. <br />
|
|
Authoritative survey lengths for each cave, as explored by expo participants, are calculated using <a href="/handbook/troggle/cavelengths.html">a script</a> which
|
|
<ol><li>uses the
|
|
<em>loop-closure corrected</em> lengths
|
|
<li>is manually curated to exclude duplicate surveys of the same cave.
|
|
</ol>
|
|
|
|
These authoritative results are maintained
|
|
in an <a href="/repositories/loser/.git/tree/docs/smklengths.ods">ODS-format spreadsheet</a>.

|
|
<p>One Survex Survey Block is one *begin/*end block of data in a survex file. Different survex blocks in the same survex file can have different dates and surveyors.
|
|
<p>Both this table and the authoritative script exclude survex files where there is no expo participant listed as a surveyor.
|
|
<p>In the early years survex was not used and the survex files have been hand-edited from earlier survey formats. The survex files and lengths recorded need checking for the 1980s and 1990s.
|
|
<p>The number of cavers excludes those attending who were not caving. This is something of a distortion as non-cavers
|
|
may still be doing useful expo-related work such as prospecting, ferrying gear and preparing food.
|
|
Non-cavers also include the bier tent and Rover Richardson, see <a href="/folk/index.html">the folk list</a> for details.
