Detailed Description

The TSL2DSatelliteHelper is used to draw satellite paths in a 2D standard data layer.

◆ path() [1/2]

static TSLEntitySet * TSL2DSatelliteHelper::path	(	const TSLCoordinateSystem *	coordSystem,
		TSLSatellite *	sat,
		const TSLTimeInstant &	currentTime,
		int	timeFrame,
		double	intTime,
		bool	afterNow = false,
		int	numPoints = 0 )

static

Calculate a satellite's ground track given a start time and duration. The path drawn is historical by default, although can be set to be predictive. The resolution of the path is determined by either the interval value or the number of points.

If the interval time given is zero then the number of points is used. Number of points is zero by default.

If neither an interval time nor a number of points is specified, or if the line cannot be created a null pointer is returned.

Note that the interval time needs to be given in minutes.

Note also that the caller owns the resulting entity set, which may contain multiple polylines due to discontinuities.

Parameters

coordSystem	the coordinate system in which the path lives
sat	the satellite
currentTime	the end time (or start time) for the path
timeFrame	the time frame, in whole minutes
afterNow	by default, false, indicating that the path is historical, if set to true, the path is predictive
intTime	the interval time, in minutes - the satellite's position is calculated after every intTime minutes
numPoints	the number of points that the polyline should contain, defaults to 0
