const BoundCRSPtr & osgeo::proj::crs::CRS::canonicalBoundCRS | ( | ) |
Return the BoundCRS potentially attached to this CRS.
In the case this method is called on a object returned by BoundCRS::baseCRSWithCanonicalBoundCRS(), this method will return this BoundCRS
CRSNNPtr osgeo::proj::crs::CRS::createBoundCRSToWGS84IfPossible | ( | io::DatabaseContextPtr | dbContext | ) | const |
Returns potentially a BoundCRS, with a transformation to EPSG:4326, wrapping this CRS.
If no such BoundCRS is possible, the object will be returned.
The purpose of this method is to be able to format a PROJ.4 string with a +towgs84 parameter or a WKT1:GDAL string with a TOWGS node.
This method will fetch the GeographicCRS of this CRS and find a transformation to EPSG:4326 using the domain of the validity of the main CRS.
GeodeticCRSPtr osgeo::proj::crs::CRS::extractGeodeticCRS | ( | ) | const |
Return the GeodeticCRS of the CRS.
Returns the GeodeticCRS contained in a CRS. This works currently with input parameters of type GeodeticCRS or derived, ProjectedCRS, CompoundCRS or BoundCRS.
GeographicCRSPtr osgeo::proj::crs::CRS::extractGeographicCRS | ( | ) | const |
Return the GeographicCRS of the CRS.
Returns the GeographicCRS contained in a CRS. This works currently with input parameters of type GeographicCRS or derived, ProjectedCRS, CompoundCRS or BoundCRS.
VerticalCRSPtr osgeo::proj::crs::CRS::extractVerticalCRS | ( | ) | const |
Return the VerticalCRS of the CRS.
Returns the VerticalCRS contained in a CRS. This works currently with input parameters of type VerticalCRS or derived, CompoundCRS or BoundCRS.
CRSNNPtr osgeo::proj::crs::CRS::stripVerticalComponent | ( | ) | const |
