I have so say I don't like the suggested position format

[N|S]degree.minute.second.f, N60.08.00.235556
degree range [0-90], decimal fraction f in arbitrary length

It doesn't seem to match anything in common use afaik - nautical,
recreational, or GIS - and incurs processing overhead converting
it for use in calculation.

After a couple of years of arguing this issue in Dublin Core, etc. I much
prefer signed decimal degrees, which is unambiguous (well, apart from axis
ordering), simple to understand and parse, and compatible with GIS data.

(Common nautical use seems to be to give position e.g.
49°04'43"N 140°17'32"E or 49°04.71N 140°17.53N, but the degree symbol is
not an ASCII character)
