GPS can be a pretty tricky subject to understand. A couple of useful points are:

• All points are given as UTM grid references. These grid references are metres east and metres north from a certain point (eastings and northings), which is determined by the UTM Zone. In Tasmania, the Zone is always 55G.
• All points on this site are given in the GDA94 datum. This supersedes the older AGD66 used on older Tasmaps, including all the original 1:25K maps. Check the legend section of your map to make sure the datum matches your GPS points.
• For our purposes GDA94 is equivalent to WGS84, which is the global standard.
• To convert a GDA94 or WGS84 grid reference to AGD66, subtract 112 from the easting and 183 from the northing. Hence if you mix up your datums, you will be about 150 metres out.

There is a good discussion of this stuff at http://www.utas.edu.au/spatial/locations/index.html .

The table below shows all the GPS points recorded in the thesarvo guides. It is designed so as to be able to be imported into your GPS. There are a couple of things you can do with this data:

1. Click on the Google Earth link, load up the KML file in Google Earth, zoom around and check it out!
2. Click on theLIST link next to each point, to load up the 1:25K topo map centred on that point
3. Click on the Google Maps link, to load the KML file up in Google Maps
4. Click on the Google Earth link, and save the KML file to your computer, and use GPSBabel ( http://www.gpsbabel.org/ ) to either load it directly to your GPS, or convert it to just about any possible format. GPSBabel isn't the easiest to use software, but its pretty damn powerful.
5. Copy and paste the table below into Excel, then covert it manually to the required format.

If you have any GPS co-ordinates to add to this list, send them to in a similar format as below.
