Store the informations for a location on a planet.
QString landscapeKey
A hint for associating a landscape to the location.
bool isUserLocation
Used privately by the StelLocationMgr.
float longitude
Longitude in degree.
QString country

State/region name (useful if 2 locations of the same country have the same name)
QString planetName
English planet name.
int altitude
Altitude in meter.
QString serializeToLine() const
Output the location as a string ready to be stored in the user_location file.
QChar role
Location role code.
static StelLocation createFromLine(const QString &line)
Parse a location from a line serialization.
static float distanceDegrees(const float long1, const float lat1, const float long2, const float lat2)
Compute great-circle distance between two locations.
float bortleScaleIndex
Light pollution index following Bortle scale.
QString getID() const
