get_SourceCoordSys Method

WRAPPER_API CoordSys& get_SourceCoordSys()

WRAPPER_API const CoordSys& get_SourceCoordSys() const

Description

The get_SourceCoordSys returns the CoordSys from which CoordPoints will be converted.

Example

void CoordTransform_getHasValidVerticalTransform(GeoCalcPBW::DataSource & data)

{

GeoCalcPBW::CoordTransform ct;

GeoCalcPBW::GeodeticCoordSys * source = data.GetGeodeticCoordSys(_towchar("BMG").c_str(), _towchar("WGS84_coordinate_system").c_str());

GeoCalcPBW::ProjectedCoordSys * target = data.GetProjectedCoordSys(_towchar("BMG").c_str(), _towchar("IA-27W").c_str());

GeoCalcPBW::VerticalReference * sourceVR = data.GetVerticalReference(_towchar("BMG").c_str(), _towchar("NGVD29_GEOID96").c_str());

GeoCalcPBW::VerticalReference * targetVR = data.GetVerticalReference(_towchar("BMG").c_str(), _towchar("ELLIPSOID_HEIGHT").c_str());
