<h1>Essential GPS information</h1>
|
||
|
|
<p>We have a regularly-updated file of all the cave entrances for the entire Schvartzmooskögel system (SMK).
|
||
|
|
This file also includes the tracks of the paths we regularly take: from Loser Alm car park to the col and to top camp,
|
||
|
|
and from top camp to Fisch Gesicht Höhle and to Tunnocks's, Balkonhöhle and Organhöhle.
|

<h2 id="down">Download the GPS essentials file from the expo server</h2>
|
||
|
|
<p>
|
||
|
|
We regularly create a new version of this essential data as the expo progresses and as expoers discover new entrances and
|
||
|
|
devise new routes to reach them.
|
||
|
|
<p>
|
||
|
|
To get the most recent version you will need to ask someone who is competent in using the version control system
|
||
|
|
(it's in loser/gpx/ and is generated from the survex data by a script). A fairly recent copy (17 July 2018)
|
||
|
|
can be downloaded from here: <a href="essentials.gpx" download>essentials.gpx</a> (190K).
|
||
|
|
Phones have a problem with a simple link like that. So with a phone you may need to try this link
|
||
|
|
<a href="https://www.wikiloc.com/outdoor-trails/carpark-stonebridge-27029006&utm_source=social&utm_medium=twitter.com&utm_campaign=badge">
|
||
|
|
Wikilocs</a>
|
||
|
|
from where you can download a short version of the file (track and one waypoint at StoneBridge only) or a Google Earth trail (you need to create a Wikiloc account first <em>and be logged-in</em> when you click on this). Or here is another <a href="https://www.wikiloc.com/wikiloc/download.do?id=27029006">direct download link</a>.
|
||
|
|
|
||
|
|
<h2 id="up">Upload the GPS essentials file to your device</h2>
|
||
|
|
<p>
|
||
|
|
This is where it gets tricky because every device and phone app does this differently.
|
||
|
|
|
||
|
|
<h3>GPS phone apps</h3>
|
||
|
|
<p>
|
||
|
|
This should work the same way whether you have an iPhone or an Android phone.
|
||
|
|
|
||
|
|
<p>We do not have a recommended app as there is nothing we have found which quite does quite what we need. We are using
|
||
|
|
<a href="http://www.gpsessentials.com/">www.gpsessentials.com</a> and <a href="https://osmand.net/">OsmAnd</a> so try one of these first. If you discover a good app, tell everyone about it.
|
||
|
|
<p>
|
||
|
|
Visit the <a href="http://www.gpsessentials.com/">www.gpsessentials.com</a> website and read the manual (top left, on the menu bar: "Manual") for how to do this.
|
||
|
|
Except that the manual doesn't tell you.
|
||
|
|
<p>The OsmAnd documentation says:
|
||
|
|
<ul>
|
||
|
|
<li>"The simplest way to view a track you've downloaded is to tap on it in your device's file manager and choose to open it in OsmAnd. After that, you'll see the track in My places - My tracks or in the Dashboard - My tracks."
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
More documentation on this to follow...

<h3>Modern Garmin handheld GPS devices</h3>
|
||
|
|
<p>
|
||
|
|
Connect the GPS device to your laptop (or the expo laptop) using the USB cable. A folder will open on the laptop showing the contents
|
||
|
|
of the device.
|
||
|
|
You will see a subfolder called "GARMIN". Open the folder "GARMIN" and copy the file essentials.gpx which you
|
||
|
|
downloaded into that folder.
|
||
|
|
|
||
|
|
<h3>Old Garmin handheld GPS devices</h3>
|
||
|
|
<p>
|
||
|
|
These need the Garmin communication protocol to import cave entrance locations (waypoints) and paths (tracks). You can't do it by simply copyingfiles.
|
||
|
|
This means that you need special software on your laptop in addition to a USB cable that connects your laptop to the Garmin device.
|

If your Garmin has a <b>mini</b>-USB socket, rather than the usual micro-USB found in phones, then you might have an "old" Garmin handheld, but some modern handhelds still use this old socket.
|
||
|
|
<p>Once you have the right cable and connected your handheld to your laptop:
|
||
|
|
<ul>
|
||
|
|
<li>On a Windows machine, use "GPSbabel for Windows" which has an easy to use graphical user interface:
|
||
|
|
<a href="https://www.gpsbabel.org/download.html">download GPS Babel</a>
|
||
|
|
<li>On a Linux machine the core gpsbabel command line utility is probably already installed;
|
||
|
|
but there is no simple, easy to use graphical interface.
|
||
|
|
Instead you must use other software such as QGIS or Viking (download using your usual Linux software installer)
|
||
|
|
which uses gpsbabel to talk to your device.
|
||
|
|
If this doesn't work then there are no useful error messages from Viking.
