<p>New in 2021 are fields for the latitude and logitude (WGS84 - the same as your GPS displays). These should be entered in degrees with decimals for fractions of a degree, e.g. 42.357 (not 42 degress 21 minutes 25 seconds, or 42 degrees 21.42 minutes).
<p>These fields exist for newly-discovered cave entrances for which we currently have no location information except for a GPS reading by the original discoverer. These discoveries have a habit of getting completely lost: so enter it so that someone can find it again to properly survey it. In due course, proper surveys will be done and the cave will be linked in to the GPX and survex survey system. If this has been done, then that is authoritative and you do not need to enter location informaiton on this form.
<p>In previous decades the location of an entrance was the <em>output</em> of a whole lot of surveying and position fixing (e.g. see <ahref="lasers.htm">laser points</a>). Today, an initial location of an entrance is available by GPS at the <em>beginning</em> of the process. So we have these fields to record the data. [We don't yet have the code to automatically add these to the <var>essentials.gpx</var> download to be used for prospecting though.]
