Member Function Documentation

convert()

OdResult OdSpatialReference::OdDatumShift::convert	(	double &	dLon,
		double &	dLat ) const

Converts coordinate (longitude, latitude) using current datum shift.

Parameters

dLon	[in/out] Longitude.
dLat	[in/out] Latitude.

Returns

Returns eOK if successful, or an appropriate error code if not.

convert3D()

OdResult OdSpatialReference::OdDatumShift::convert3D	(	double &	dLon,
		double &	dLat,
		double &	dHeight ) const

Converts coordinate (longitude, latitude, height) using current datum shift.

Parameters

dLon	[in/out] Longitude.
dLat	[in/out] Latitude.
dHeight	[in/out] Height.

Returns

Returns eOK if successful, or an appropriate error code if not.

getAt()

OdResult OdSpatialReference::OdDatumShift::getAt	(	OdUInt32	uIndex,
		bool &	bIsInversed,
		OdGeodeticTransformationDefinitionPtr &	pGeodeticTransformationDefinition ) const

Returns the geodetic transformation definition of this datum shift.

Parameters

uIndex	[in] Index of geodetic transformation definition object.
bIsInversed	[out] If true - geodetic transformation definition object is used as inversed.
pGeodeticTransformationDefinition	[out] Pointer to an OdGeodeticTransformationDefinition object.

Returns

Returns eOK if successful, or an appropriate error code if not.

getCount()

OdResult OdSpatialReference::OdDatumShift::getCount

(

OdUInt32 &

uCount

)

const

Returns the geodetic transformation definitions count of this datum shift.

Parameters

uCount

[out] Count of geodetic transformation definitions.

Returns

Returns eOK if successful, or an appropriate error code if not.

getDatumShift()

static OdResult OdSpatialReference::OdDatumShift::getDatumShift ( const OdGeodeticTransformationDefinition * pGeodeticTransformationDefinition, bool bInverse, OdDatumShiftPtr & pDatumShift )

static

Gets the datum shift object from geodetic transformation definition.

Parameters

pGeodeticTransformationDefinition	[in] Pointer to an OdGeodeticTransformationDefinition object.
bInverse	[in] Direction of resulted datum shift: true - inversed, false - forward.
pDatumShift	[out] Pointer to an OdDatumShift object.

Returns

Returns eOK if successful, or an appropriate error code if not.

getPath()

OdResult OdSpatialReference::OdDatumShift::getPath

(

OdGeodeticPathDefinitionPtr &

pGeodeticPathDefinition

)

const

Returns the geodetic path definition of this datum shift.

Parameters

pGeodeticPathDefinition

[out] Pointer to an OdGeodeticPathDefinition object.

Returns

Returns eOK if successful, or an appropriate error code if not.

isNullTransformation()

bool OdSpatialReference::OdDatumShift::isNullTransformation

(

)

const

Determines whether this datum shift has no transformations to be applied.

Returns

true if this datum shift object has no transformations to be applied.

load() [1/2]

static OdResult OdSpatialReference::OdDatumShift::load ( const OdDatumDefinition * pDatumSource, const OdDatumDefinition * pDatumTarget, OdDatumShiftPtr & pDatumShift )

static

Creates datum shift by source and target datum definitions.

Parameters

pDatumSource	[in] Pointer to source datum definition.
pDatumTarget	[in] Pointer to target datum definition.
pDatumShift	[out] Pointer to datum shift, result of loading.

Returns

Returns eOK if successful, or an appropriate error code if not.

load() [2/2]

static OdResult OdSpatialReference::OdDatumShift::load ( const OdString & sDatumSource, const OdString & sDatumTarget, OdDatumShiftPtr & pDatumShift )

static

Creates datum shift by source and target datum names.

Parameters

sDatumSource	[in] Name to source datum.
sDatumTarget	[in] Name to target datum.
pDatumShift	[out] Pointer to datum shift, result of loading.

Returns

Returns eOK if successful, or an appropriate error code if not.
