Needs a nice method to get the lengths of polygons.

Als Orthodrome? Als Loxodrome? als einfache Länge einer Tangente im Dreieck? Spezifizier bitte mal

Neither. This one: https://en.wikipedia.org/wiki/Vincenty%27s_formulae It is e.g. integrated here: https://pypi.python.org/pypi/geopy/0.98 (which brings other nice geoservices like geolocator api support, etc)

Interesting: Leaflet.Draw already pops up a hint telling how long the drawn path currently is.

As per previous comment, i'm upping this to 1.1

I think this is pretty well done via geojson & leaflet.draw. We should maybe make some accuracy tests to see if the values are converted correctly - i do assume so.
