Ryan! Hoi!

As far as I have looked at a number of your observations, it seems that all your localities are hidden. (And some, like this one, is quite a distance from the ocean!).

Please be diligent with localities. As you should know, these data are really used by real scientists for real science, which may fail if the primary data are erroneous. Locality information is, after the identity of the organism, probably the most basic information of all biological observations (and sometimes it's the other way around).

Please ask for help if you need assistance with localities. The coordinates of many diving localities are easily available. Never hide a locality because you fear your mapwork is shoddy! Rather ask in time.

And then please fix all your localities that are not up to standard. But please do not be put off -- your contributions look great to me, but as a landrat I cannot really evaulate them.

If I am not mistaken Ryan is a real scientist. He operates a ROV for SAIAB, and some of the operations are in sensitive areas. Also mostly not in recreational dive sites listed on the SeaKeys page, as they are too deep for recreational divers.
It is possible that some site locations have been loaded incorrectly, but there is no way for us regular users to check. I think only Tony can see the real positions. Ryan will have access to accurate site positions - you don't run a ROV without knowing exactly where you are.
Nevertheless, a hidden location should ideally show in a reasonably plausible way. Marine should not display entirely inland, and terrestrial should not display entirely over the sea.

Hidden localities

Hidden localities show as the upper left hand corner of their 10X10km filter, displaying a grid cell for the locality.
Or more simply, hidden localities display at the accuracy of 0.1 decimal degree, by simply truncating the coordinates at one decimal place. The actual coordinates displayed are truncated at the degree.
This is a legal prescription (SANBI may not reveal the locality of sensitive species to third parties without a contract of confidentiality) and this is the way SANBI has to operate.

But the grid square shown on iSpot for hidden locality is the total area of the 10X10km cell, and the boundaries of the cell are accurate. The locality may be anywhere within that cell, but ARE inside the cell displayed.

So if the cell includes land and sea and the habitat is given as marine, then the locality is probably in the sea bit.
But if the cell shown is entirely on land, or entirely on sea, contrary to the habitat, then there is an error!!!

In this case, there is an error. Both clearly from the grid cell being entirely on land and, yes I checked (but there was no need for me to do so, it is clear problematic from the cell alone).

Thanks, most of that makes sense

If I understand correctly:
The coordinates are stored in the precision they are entered,
The display formula drops all decimals beyond the first and displays the top left corner of a 10x10km square at the truncated position, and the real position is therefore to the right and below that corner, but within 0.1 degree of it, and almost always inside the square, since 0.1 degree is less than or equal to 6 nautical miles or 11.1km.

Spot on.

(apart from that at zoomed out scales the square is slightly exaggerated in size).

And the detailed data are potentially available to bone fide researchers prepared to contractually agree to keeping the localities confidential.

For sensitive localities, or for other reasons, it is best to state why one has hidden the locality. Although with dive sites this is assumed: but still best to use the "standardized sites" given at http://ispot.org.za/SeaKeys

Thanks for pointing this out.
I accidently entered the coords in the incorect format. deg, min, dec. I have corrected them.
Kind regards,
Ryan

Thanks.there are ways to

Thanks.

there are ways to speed up entering your locality information: see http://ispot.org.za/iSpot101_Localities

Unfortunately, iSpot cannot automatically convert different formats into decimal degrees, which is the default data exchange (including the exif in your pictures if you have a GPS enabled camera).
