Ken,
The best option is to store the information in decimal degrees rather
than in degrees, minutes, and seconds. The information stored in decimal
degrees can be use in any GIS software packages. You can use the
below formula to convert degrees, minutes, and seconds to decimal
degrees.
DD = D + (M / 60) + (S / 3600)
Hope this information is helpful.
Thanks,

Subject: Metadata standards for GPS coordinates?
To: [log in to unmask]
Folks, my current work involves working in digital collections metadata,
and some digital objects have fairly detailed GPS coordinates provided.
I’m wondering if there is a “best practices” standard for their format,
which may vary considerably. Here are a couple of examples from recent
submissions:
N 68°22.987´/W 146°24.882´
N 48 15.048° W 121 48.973°
The first one looks better to me, but any advice on proper format,
including punctuation, will be welcome. I also note that it appears the
degree sign can be problematic for Content-dm to recognize, so maybe the
word “degrees” should be spelled out. Sorry if this is not as
map-related as it should be, but it seems a good forum to reach people
who might also know something about this related subject.
