<p>The (strongly) recommended procedure is to take a specific GPS measurement at a well-defined point and to write down the location on your prospecting survey notes. Then for a new discovery it will be copied onto the New Cave data sheet.
<p>Note that we record the location in degrees and decimals of degrees: <code>47.69055 13.80841</code> and the altitude is in metres.
<p>The altitude is not nearly as vital as the lat/long numbers. GPS altitudes are still pretty bad, and even the new Galileo system won't promise anything better than &plusmn; 0.4m in 2030. (If you take the altitude from a track while moving the altitude can easily be 15m wrong.)
<p>The altitude is almost useless: we get better altitudes by using the lat/long numbers together with a laser scan of the plateau topography. GPS altitudes will continue to be pretty bad, and even the new Galileo system won't promise anything better than &plusmn; 0.4m in 2030. (If you take the altitude from a track while moving the altitude can easily be 15m wrong.)
<p>See <a href="#location">the bottom of this page</a> for how the location information is typed in.
