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,

-Wangyal

style="font-size: 10pt; font-family: Arial;">Folks, my current work
involves working in digital
collections metadata, and some digital objects have fairly detailed GPS
coordinates provided.&nbsp; I&#8217;m wondering if there is a
&#8220;best practices&#8221;
standard for their format, which may vary considerably.&nbsp; Here are a
couple of
examples from recent submissions:<o:p></o:p></span></font></p>

style="font-size: 10pt; font-family: &quot;Courier New&quot;;">The first
one
looks better
to me, but any advice on proper format, including punctuation, will be
welcome.&nbsp; I also note that it appears the degree sign can be
problematic for
Content-dm to recognize, so maybe the word &#8220;degrees&#8221; should be
spelled out.<o:p></o:p></span></font></p>
