Accessible GIS coordinates

Looking for recommendations on how best to present GIS coordinates in a PDF
tour book. The tour book has a narrative description of the location, along
with GIS coordinates.

2 questions:

1. The client’s original GIS format is Degrees / Minutes / Seconds.
Sample: 41° 24' 12.1674", 2° 10' 26.508"

In our screen reader tests, the minutes and seconds aren’t voiced regardless
of which Unicode character is used — Prime U+2032 or U+02B9, and
Double-Prime U+2033 or U+02BA.

Is there another symbol for minutes and seconds to use that is voiced by
screen readers? Is there another way to handle this?

2. Is there consensus on which GIS format to use? Three sample formats
follow.

· Decimal degrees: 41.40338, 2.17403

· Degrees, minutes and seconds: 41° 24' 12.1674", 2° 10' 26.508"

· Degrees and decimal minutes: 41 24.2028, 2 10.4418

Thanks all,

—Bevi Chagnon
