Sorry for the late reply! To be honest I hadn't considered it because when I wrote this it was originally to solve a specific problem and that situation always has them in lat/lon rather than lon/lat, but what I'll add to the future to do list is maybe a toggle so if you have them in lon/lat order you can society that and feed them in that way.

I get your point on "DD" being cryptic, I will consider that. Maybe rather than DD, DM, DMS, DecDeg, DegMin, DegMinSec or something slightly more descriptive. Hm.
