Detailed Description

A class used to convert gps coordinates to coordinates on a flat xy-plane, and vice versa.

The xy-plane will always be measured in meters. Additionally, the xy-plane will be aligned such that +x = +lat, +y = -lon.

Constructor & Destructor Documentation

GPSToMetersConverter()

GPSToMetersConverter::GPSToMetersConverter	(	const GPSDatum &	datum,
		const navtypes::gpscoords_t &	origin )

Construct a new GPSToMetersConverter object.

Parameters

datum	The datum to use for the GPS calculations.
origin	The gps coordinates of the origin of the xy-plane.

Member Function Documentation

getMetersPerDegLat()

double GPSToMetersConverter::getMetersPerDegLat

(

)

const

Get the number of meters per degree of latitude.

Given the datum and the origin, this is a constant.

getMetersPerDegLon()

double GPSToMetersConverter::getMetersPerDegLon

(

)

const

Get the number of meters per degree of longitude.

Given the datum and the origin, this is a constant.
