<p>The SRTM altitude is that measured at a nearby reference point. The horizontal distance between the survey station and the SRTM reference point is shown in the "SRTM ref" column. It is always less than 35m for our dataset. Differences between the recorded altitude and the SRTM altitude are in <b>bold</b> if the discrepancy is more than 60m vertically.

<p>The data in the table immediately below has been hand-entered and is sometimes very wrong.
<p>The Lat. Long. coordinates are manually entered using a phone or a hand-held GPS device at (or near) the entrance.
<p>For the Cave column, if there is an official cave name, then it is shown.
Otherwise whatever other name we can find for it is shown <em>in italics</em>.

<h3>All entrances in Trogggle</h3>
<p> See also <a href="/entrances">Entrances list</a>.
<p>But the Entrances - the objects in the troggle system - are not properly connected to the dataset which is the combined set of survex data. They are only linked - and only implicitly - by the tag name. The data in the table below is calculated directly from
the assemblage of survex files, including fixed point files, and is probably 'correct'.
<p>But which coordinate system are they in ? Read these three articles to find out:
<br>
<a href="/stations">Troggle UTM and lat./lomg. and altitude report</a><br>
<a href="/entrances">Troggle entrances</a><br>
<p>But the Entrances - the objects in the troggle system - are not identical to the dataset Survey Stations which is the combined set of survex data. They are only linked - and only implicitly - by the station name, e.g. '1623.gps00.p78' which refers to a *fix line in one of the survex files (in the fixedpts/ folder). Each Entrance can have two stations associated with it: the tag station and the other station.
