CrsDefinitionFormat
CRS definition formats.
Definition: qgis.h:2077
Contains information about a celestial body.
QgsCoordinateReferenceSystem crs
QgsCoordinateReferenceSystem object representing the user-defined CRS.
A registry for known coordinate reference system (CRS) definitions, including any user-defined CRSes.
void userCrsAdded(const QString &id)
Emitted whenever a new user CRS definition is added.
void userCrsChanged(const QString &id)
Emitted whenever an existing user CRS definition is changed.
void userCrsRemoved(long id)
Emitted when the user CRS with matching id is removed from the database.
void crsDefinitionsChanged()
Emitted whenever an operation has caused any of the known CRS definitions (including user-defined CRS...
This class represents a coordinate reference system (CRS).
Contains information about a PROJ operation.
