Member Data Documentation

accuracy

double QgsDatumTransform::TransformDetails::accuracy = 0

Transformation accuracy (in meters)

Definition at line 188 of file qgsdatumtransform.h.

areaOfUse

QString QgsDatumTransform::TransformDetails::areaOfUse

Area of use string.

This is only available for single step coordinate operations. For multi-step operations, check operationDetails instead.

bounds

Definition at line 238 of file qgsdatumtransform.h.

authority

QString QgsDatumTransform::TransformDetails::authority

Authority name, e.g.

EPSG.

This is only available for single step coordinate operations. For multi-step operations, check operationDetails instead.

Definition at line 196 of file qgsdatumtransform.h.

bounds

QgsRectangle QgsDatumTransform::TransformDetails::bounds

Valid bounds for the coordinate operation.

areaOfUse

Definition at line 244 of file qgsdatumtransform.h.

code

QString QgsDatumTransform::TransformDetails::code

Identification code, e.g.

"8447" (For EPSG:8447).

This is only available for single step coordinate operations. For multi-step operations, check operationDetails instead.

Definition at line 204 of file qgsdatumtransform.h.

grids

QList< QgsDatumTransform::GridDetails > QgsDatumTransform::TransformDetails::grids

Contains a list of transform grids used by the operation.

Definition at line 249 of file qgsdatumtransform.h.

isAvailable

bool QgsDatumTransform::TransformDetails::isAvailable = false

true if operation is available.

If false, it likely means a transform grid is required which is not available.

Definition at line 228 of file qgsdatumtransform.h.

name

QString QgsDatumTransform::TransformDetails::name

Display name of transform operation.

Definition at line 186 of file qgsdatumtransform.h.

operationDetails

QList< QgsDatumTransform::SingleOperationDetails > QgsDatumTransform::TransformDetails::operationDetails

Contains information about the single operation steps used in the transform operation.

Note

Only used in builds based on on Proj >= 6.2

Since

QGIS 3.10

Definition at line 257 of file qgsdatumtransform.h.

proj

QString QgsDatumTransform::TransformDetails::proj

Proj representation of transform operation.

Definition at line 184 of file qgsdatumtransform.h.

remarks

QString QgsDatumTransform::TransformDetails::remarks

Remarks for operation, from EPSG registry database.

This is only available for single step coordinate operations. For multi-step operations, check operationDetails instead.

Definition at line 220 of file qgsdatumtransform.h.

scope

QString QgsDatumTransform::TransformDetails::scope

Scope of operation, from EPSG registry database.

This is only available for single step coordinate operations. For multi-step operations, check operationDetails instead.

Definition at line 212 of file qgsdatumtransform.h.
