Function Documentation

static void UTM::LLtoUTM	(	const double	Lat,
		const double	Long,
		double &	UTMNorthing,
		double &	UTMEasting,
		char *	UTMZone
	)		[inline, static]

Convert lat/long to UTM coords. Equations from USGS Bulletin 1532

East Longitudes are positive, West longitudes are negative. North latitudes are positive, South latitudes are negative Lat and Long are in fractional degrees

static void UTM::UTM	(	double	lat,
		double	lon,
		double *	x,
		double *	y
	)		[inline, static]

Utility function to convert geodetic to UTM position

Units in are floating point degrees (sign for east/west)

Units out are meters

Todo:

deprecate this interface in favor of LLtoUTM()

static char UTM::UTMLetterDesignator

(

double

Lat

)

[inline, static]

Determine the correct UTM letter designator for the given latitude

Returns:

'Z' if latitude is outside the UTM limits of 84N to 80S

static void UTM::UTMtoLL	(	const double	UTMNorthing,
		const double	UTMEasting,
		const char *	UTMZone,
		double &	Lat,
		double &	Long
	)		[inline, static]

Converts UTM coords to lat/long. Equations from USGS Bulletin 1532

East Longitudes are positive, West longitudes are negative. North latitudes are positive, South latitudes are negative Lat and Long are in fractional degrees.
