static Q_DECL_DEPRECATED QList< QgsDatumTransform::TransformPair > | datumTransformations (const QgsCoordinateReferenceSystem &source, const QgsCoordinateReferenceSystem &destination) |
Returns a list of datum transformations which are available for the given source and destination CRS. | |
static Q_DECL_DEPRECATED QgsDatumTransform::TransformInfo | datumTransformInfo (int datumTransformId) |
Returns detailed information about the specified datumTransformId. | |
static Q_DECL_DEPRECATED QString | datumTransformToProj (int datumTransformId) |
Returns a proj string representing the specified datumTransformId datum transform ID. | |
static QList< QgsDatumTransform::TransformDetails > | operations (const QgsCoordinateReferenceSystem &source, const QgsCoordinateReferenceSystem &destination, bool includeSuperseded=false) |
Returns a list of coordinate operations available for transforming coordinates from the source to destination CRS. | |
static Q_DECL_DEPRECATED int | projStringToDatumTransformId (const QString &string) |
Returns the datum transform ID corresponding to a specified proj string. | |
static QgsDatumTransform::TransformDetails | transformDetailsFromPj (PJ *op) |
Returns the transform details for a Proj coordinate operation op. | |

Returns a list of datum transformations which are available for the given source and destination CRS.
Definition at line 65 of file qgsdatumtransform.cpp.
|
static |
Returns detailed information about the specified datumTransformId.
If datumTransformId was not a valid transform ID, a TransformInfo with TransformInfo::datumTransformId of -1 will be returned.

static |
Returns a proj string representing the specified datumTransformId datum transform ID.
Definition at line 154 of file qgsdatumtransform.cpp.
|
static |
Returns a list of coordinate operations available for transforming coordinates from the source to destination CRS.
This list is sorted in order of preference, with the most preferable operation listed first.
Not all operations may be available for use. Check QgsDatumTransform::TransformDetails::isAvailable first. Operations may require grid shift files which are not available on the local install.
If includeSuperseded is true
, superseded (but not deprecated) transforms will be included in the results. This requires Proj >= 6.2.

Returns the datum transform ID corresponding to a specified proj string.
Returns -1 if matching datum ID was not found.
