class qgis.gui.QgsCoordinateReferenceSystemModel[source]¶

Note

Prior to QGIS 3.36 this was available as QgsCoordinateReferenceSystemModel.Roles

Added in version 3.36.

NodeType: Corresponds to the node’s type

Available as QgsCoordinateReferenceSystemModel.RoleNodeType in older QGIS releases.
Name: The coordinate reference system name

Available as QgsCoordinateReferenceSystemModel.RoleName in older QGIS releases.
AuthId: The coordinate reference system authority name and id

Available as QgsCoordinateReferenceSystemModel.RoleAuthId in older QGIS releases.
Deprecated: True if the CRS is deprecated

Available as QgsCoordinateReferenceSystemModel.RoleDeprecated in older QGIS releases.
Type: The coordinate reference system type

Available as QgsCoordinateReferenceSystemModel.RoleType in older QGIS releases.
GroupId: The node ID (for group nodes)

Available as QgsCoordinateReferenceSystemModel.RoleGroupId in older QGIS releases.
Wkt: The coordinate reference system’s WKT representation. This is only used for non-standard CRS (i.e. those not present in the database).

Available as QgsCoordinateReferenceSystemModel.RoleWkt in older QGIS releases.
Proj: The coordinate reference system’s PROJ representation. This is only used for non-standard CRS (i.e. those not present in the database).

Available as QgsCoordinateReferenceSystemModel.RoleProj in older QGIS releases.
Group: Group name.

Added in version 3.42.
Projection: Projection name.

Added in version 3.42.

addCustomCrs(self, crs: QgsCoordinateReferenceSystem) → QModelIndex[source]¶

Adds a custom crs to the model.

This method can be used to add CRS which aren’t present in either the standard PROJ SRS database or the user’s custom CRS database to the model.

authIdToIndex(self, authId: str | None) → QModelIndex[source]¶

Retrieves the model index corresponding to a CRS with the specified authId.

Returns an invalid index if the CRS was not found.
