A while ago i've addressed this topic, too:
[url]A few comments on GPS coordinates in Opus]
It would be good, if we could enter both, decimal or ° ' " formats, because it's a hassle to convert the decimal format, which is mostly used when you get your data from BING or Google maps, to the format Opus uses.
There are a couple web sites out there, where you can make the conversion, but it's still a lot of extra work. I guess, that it's quite a simple conversion algorithm, so maybe it could be implemented in Opus?
