CreateEllipsoid Constructor

Updated 
WRAPPER_API static Ellipsoid* CreateEllipsoid()
 

Description

The CreateEllipsoid constructor creates a new instance of the Ellipsoid class.  Upon construction, The Ellipsoid has a SemiMajor radius of one meter, a SemiMinor radius of 1 meter, and InvFlatDefinitive set to true.  

 

Example

void Ellipsoid_CreateEllipsoid(GEOCALCPBW_NAMESPACE::DataSource & data)
{
GEOCALCPBW_NAMESPACE::Ellipsoid * ell = GEOCALCPBW_NAMESPACE::Ellipsoid::CreateEllipsoid();
GEOCALCPBW_NAMESPACE::LinearValue semiMaj;
semiMaj.set_InMeters(6378137);
ell->set_SemiMajor(semiMaj);
ell->set_InvFlatDefinitive(false);
GEOCALCPBW_NAMESPACE::LinearValue semiMin;
semiMin.set_InMeters(6356752.31424518);
ell->set_SemiMinor(semiMin);
 
GEOCALCPBW_NAMESPACE::GeodeticPoint * fromPt = data.GetGeodeticPoint(L"BMG", L"GEODETIC_POINT_DEGREES");
GEOCALCPBW_NAMESPACE::GeodeticPoint * toPt = data.GetGeodeticPoint(L"BMG", L"GEODETIC_POINT_DEGREES");
fromPt->set_InUnits(-77.36, 45.45);
toPt->set_InUnits(-77.43, 46.68);
double azimuthAhead;
double azimuthBack;
double geodesic;
if(! ell->ComputeInverse(*fromPt, *toPt, geodesic, azimuthAhead, azimuthBack))
{
AfxMessageBox("ComputeInverse failed");
}
 
delete ell;
delete fromPt;
delete toPt;
}
