bool Eaagles::Terrain::QuadMap::isDataLoaded

(

)

const [virtual]

Has the data been loaded Locates an array of (at least two)elevation points (and sets valid flags if found) returns the number of points found within this QuadMap

Implements Eaagles::Simulation::Terrain.

virtual unsigned int Eaagles::Terrain::QuadMap::getElevations	(	LCreal *const	elevations,
		bool *const	validFlags,
		const unsigned int	n,
		const double	lat,
		const double	lon,
		const LCreal direction const LCreal	maxRng,
		const bool	interp = false
	)			const [virtual]

elevations - The elevation array (meters) validFlags - Valid elevation flag array (true if elevation was found) n - Size of elevation and valdFlags arrays; lat - Starting latitude (degs) lon - Starting longitude (degs); direction - True direction (heading) angle of the data (degs) maxRng - Range to last elevation point (meters); interp - interpolate between elevation posts (default: false)

bool Eaagles::Terrain::QuadMap::getElevation	(	LCreal *const	elev,
		const double	lat,
		const double	lon,
		const bool	interp = false
	)			const [virtual]

Locates an elevation value (meters) for a given reference point and returns it in 'elev'. Function returns true if successfull, otherwise 'elev' is unchanged elev - elevation value (meters); lat - Reference latitude (degs) lon - Reference longitude (degs); interp - interpolate between elevation posts (default: false)

Implements Eaagles::Simulation::Terrain.
