Surely it's much easier than that. You just go the settings in your GPS and
choose decimal degrees. Decimal degrees is far simpler and less prone to errors
than other standards. The worst problem is when people confuse decimal minutes
for degrees, minutes and seconds on their own device, leading to errors up to
half a kilometre or so. Accuracy depends on everyone using standard notation
for the division of degrees minutes and seconds and there is no standard for
this.
For example, here are the many ways I have seen deg min sec represented (excuse
the degree sign):
35o 2.7'
35o 2' 42"
35o 02.70
35o 02 42
35 02.70
35:02.70
...and so the list goes on and on.
However, with decimal degrees, where's the confusion?
35.045o
It's MUCH simpler and less prone to error. So I don't think the people who
create websites should be worrying about programming various sophisticated
fail-safes when such fail-safes are still prone to error, as users commonly
misread their own devices.
Set your device to decimal degrees and no longer does the user or receiver of
data have to worry any more.

Simon.
