Detailed Description

Specifies geographic location by latitude and longitude.

Latitude is a geographic coordinate that specifies the north-south position (φ, phi).

Longitude is a geographic coordinate that specifies the east-west position (λ, lambda).

LatLon is meant to be similar to QGeoCoordinate (part of Qt since 5.2). This Qt class might eventually replace LatLon. QGeoCoordinate has altitude as an additional property which is rarely used in Mapper at the moment.
