set_TargetDatum Method

WRAPPER_API void set_TargetDatum(const HorizontalDatum &value)

Description

The set_TargetDatum method sets the HorizontalDatum that is used as the target of this DatumShift.

Example

void DatumShift_setTargetDatum(GeoCalcPBW::DataSource & data)

{

GeoCalcPBW::DatumShift ds(GeoCalcPBW::DatumShift::ClassType::BursaWolfe);

GeoCalcPBW::HorizontalDatum * source = data.GetHorizontalDatum(L"BMG", L"CH1903");

GeoCalcPBW::HorizontalDatum * target = data.GetHorizontalDatum(L"BMG", L"WGS84");

GeoCalcPBW::Envelope * envelope = data.GetEnvelope(L"BMG", L"CH1903_coordinate_system_envelope");

ds.set_SourceDatum(*source);

ds.set_TargetDatum(*target);

ds.set_Envelope(*envelope);

if(ds.get_Parameters().Exists(L"dx"))

{

GeoCalcPBW::LinearValue lv;

lv.set_InMeters(660.077);

ds.get_Parameters().set_LinearItem(L"dx", lv);

}

if(ds.get_Parameters().Exists(L"dy"))

{

GeoCalcPBW::LinearValue lv;

}

{

}

GeoCalcPBW::AngularUnit * au = data.GetAngularUnit(L"BMG", L"ARCSECONDS");

GeoCalcPBW::AngularValue av;

av.set_Units(*au);

if(ds.get_Parameters().Exists(L"rx"))

{

}

ds.get_Parameters().set_AngularItem(L"rz", av);

}

if(ds.get_Parameters().Exists(L"k"))

{

ds.get_Parameters().set_FloatItem(L"k", 5.66);

}

GeoCalcPBW::GeodeticPoint * sourcePt = data.GetGeodeticPoint(L"BMG", L"GEODETIC_POINT_DEGREES");
