<h1>Entrance locations</h1>
|
|
|
|
<p>
|
|
These are all the locations specified in Northing/Easting coordinates in the system.
|
|
This report is to help you sort out and fix the bad data in our records. You can see from the tables here
|
|
that UTM data sometimes have Northings and Eastings swapped, or UTM is used when it is intended to be
|
|
BMN and vice versa.
|
|
|

|
Coordinate systems in Austria are explained in:<br>

<p>The data in the table immediately below has been hand-entered and is sometimes very wrong.
|
|
<table>
|
|
<tr><th>Cave</th><th>Entrance</th><th>Easting</th><th>Northing</th><th>tag</th><th>tag exact</th><th>tag other</th><th>slug</th></tr>
|
|
{% for ent in ents %}
|
|
<tr>
|
|
<td style="text-align:left"><a href="/cave/{{ent.cached_primary_slug}}">
|
|
{% for c in ent.cavelist %}{{c.official_name|safe}}{% endfor %}</a></td>
|
|
<td style="text-align:left">{{ent.name|safe}}</td>
|
|
<td style="text-align:right">{{ent.easting|floatformat:2}}</td>
|
|
<td style="text-align:right">{{ent.northing|floatformat:2}}</td>
|
|
<td style="text-align:right">{{ent.tag_station}}</td>
|
|
<td style="text-align:right">{{ent.exact_station}}</td>
|
|
<td style="text-align:right">{{ent.other_station}}</td>
|
|
<td style="text-align:right">{{ent.slug}}</td>
|
|
</tr>
|
|
{% endfor %}
|
|
</table>
|
|
|
|
<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:
