Subject: Add a "Start Mapping" button
X-Git-Tag: live~5377^2~42
X-Git-Url: https://git.openstreetmap.org./rails.git/commitdiff_plain/1a51f2187127f7376e2118b5a4ced49123b0504a

Add a "Start Mapping" button

Position is determined in one of two ways: lat/lon query
parameters (with helpful text from a nominatim reverse
geocode), or HTML5 geolocation.
