<div class="">One Subsurface question for you. I looked
and saw that there have been requests to be able to
access an online list of dive sites so you don’t have to
recreate a dive site (with GPS coordinates) for multiple
divers that were together. This would have been handy
for us since all three of us are logging our dives in
Subsurface. Is there ongoing work to develop the ability
to pick a site from an online database? Is that
something I can help develop?</div>

<p>There are some important things with respect to dive sites. Maybe
some of this is perfectly evident to most of you, so I may be
wasting my breath.<br>
</p>
<p>1) I have never been convinced that writing the dive locations
into the dive log XML is the best solution. The dive sites are
currently managed in a totally separate subsystem of functions,
compared to actual dive management. There is probably no reason to
keep the dive site info within the dive log. One of the downsides
of the current handling is that redundant dive sites often remain
in the database.<br>
</p>
<p>2) One should be able to do dive site management when there is no
Internet access. This means that Subsurface should have a local
copy of all dive sites used in the dive log on that computer. I
think the current way of using hashes of dive sites in the local
XML divelog is pretty efficient.The retrieval of dive sites from
an Internet-based source would also need to be reasonably fast.<br>
</p>
<p>3) If there is a local database of dive sites on my computer,
does this get backed up on the cloud in the same way as the dive
log? What would the recovery options be if I lost my local dive
site data?<br>
</p>
<p>3) I have on occasion used Internet-based information about dive
sites, but these databases never included my dive sites and
therefore has not been very useful. This may be because I prefer
to have the coordinates of the actual dive site within the broader
reef, accurate to maybe 50m. I mostly get coordinates by taking a
GPS in a sealed container and which logs coordinates every 2
minutes from which it is rudimentary to recover the appropriate
coordinates.</p>
<p>4) There is also the possibility of showing dive site coordinates
and other textual descriptive details for that site when clicking
on the Subsurface map.<br>
</p>
<p>I would love to hear the opinion of divers (such as Henrik) who
use dive site databases more extensively.</p>
<p>Kind regards,</p>
