Detailed Description

Store the informations for a location on a planet

Constructor & Destructor Documentation

◆ StelLocation()

StelLocation::StelLocation	(	QString	lName,
		QString	lState,
		QString	lRegion,
		float	lng,
		float	lat,
		int	alt,
		int	populationK,
		QString	timeZone,
		int	bortleIndex,
		QChar	roleKey = `'X'`,
		QString	landscapeID = `""`
	)

lName location name
lState may be usedful if region has more than one such name
lRegion must be the long name of UN UM49 only! (E.g., "Western Europe")
lng geographical longitude, east-positive
lat geographical latitude, north-positive
alt altitude above mean sea level
populationK population in thousands
timeZone IANA timezone string like "Europe/Vienna" or "UT-7"
bortleIndex light polution hint
roleKey code for location role.
landscapeID a fitting landscape

◆ distanceDegrees()

float StelLocation::distanceDegrees	(	const float	otherLong,
		const float	otherLat
	)		const

inline

arguments given in decimal degrees

◆ distanceKm()

double StelLocation::distanceKm	(	const double	otherLong,
		const double	otherLat
	)		const

static

All angles (args and result) are in degrees.

Returns: azimuth counted from north or south as set in the StelApp preferences, in [0...360].

◆ getAzimuthForLocation() [2/2]

double StelLocation::getAzimuthForLocation	(	double	longTarget,
		double	latTarget
	)		const

All angles (args and result) are in degrees.

Returns: azimuth counted from north or south as set in the StelApp preferences, in [0...360].

Field Documentation

◆ ianaTimeZone

QString StelLocation::ianaTimeZone

Note that timezone names under various OSes may be different than those used in Stellarium's location database (e.g. Ubuntu:Asia/Kolkata=Windows:Asia/Calcutta), which requires some translation effort during the loading process. After loading from the location DB, the ianaTimeZone should contain the full name which may differ from the database name.

◆ role

QChar StelLocation::role

Possible values:

C or B is a capital city
R is a regional capital
N is a normal city (any other type of settlement)
O is an observatory
L is a spacecraft lander
I is a spacecraft impact
A is a spacecraft crash
X is an unknown or user-defined location (the default value).
! is an invalid location.
