Programmer's opinion chiming in here: Putting seconds to "0" may
be a problem if the readout IS actually zero for a location. I'd
prefer two separate checkboxes labelled
"[ ] do not publish precise location" and
"[ ] no valid GPS data" to avoid ambiguity in the database ("was
this zero, or is this supposed to be private?")
Then we could do this:
- those that checked the "do not publish precise location" would
not have a link to MultiMap on their page
- presenting the location on the large map will usually not
sacrifice privacy, because with 1 px. = 5 km, this won't give
away anything.
- create a "non-mapped" list of panoramas without valid GPS and
present it on an empty area on the world map, if necessary, for
those that do not want or can not give a GPS coordinate (because
i guess the map may be quite popular for browsing the panoramas...)
- and if you really don't want to give away a GPS, you could
check "do not publish precise location" and add or subtract a
minute or two from the GPS. Even a rough estimation of the
location would be enough to look good on the map :-)
Of course, i'm also lazy enough to advocate the use of decimal
coordinates in the database ;-) but that shouldn't be a problem -
a simple four-field form with "enter D/M/S [ ] [ ] [ ] or decimal
[ ]" and a small converter javascript could easily handle this
right when entering the data. Decimal is needed for the MultiMap
call and my map programming is easier if i don't have to do the D
+ M/60 + S/3600 thing ;-)
