<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.
|
|
|
|
<p>

|
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.

<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:
