Detailed Description

Calculate position on Earth.

Member Typedef Documentation

◆ VEC_t

typedef cVecT2<double> GrayLib::cGeospatial::VEC_t

Member Function Documentation

◆ AddDistMeters()

cGeoPos GRAYCALL GrayLib::cGeospatial::AddDistMeters ( const cGeoPos &  p1,
double  dx,
double  dy 
)
static

Calculate new position after adding meters. As long as dx and dy are small compared to the radius of the earth and you don't get too close to the poles. Latitude: 1 deg = 110.574 km Longitude : 1 deg = 111.320*cos(latitude) km

◆ GetDistMeters()

double GRAYCALL GrayLib::cGeospatial::GetDistMeters ( const cGeoPos &  p1,
const cGeoPos &  p2 
)
static

Returns the distance between two points on the Earth. (in Meters) Convert spherical units lat/long to distance in Meters. http://www.nhc.noaa.gov/gccalc.shtml Direct translation from http://en.wikipedia.org/wiki/Haversine_formula

Returns
The distance between the two points in Meters
