Detailed Description

template<typename Coordinate, typename T = typename Coordinate::value_type>
class cuproj::projection< Coordinate, T >

A projection transforms coordinates between coordinate reference systems.

Projections are constructed from a list of operations to be applied to coordinates. The operations are applied in order, either forward or inverse.

Template Parameters

Coordinate	the coordinate type
T	the coordinate value type. Specify this if Coordinate does not have a value_type

Constructor & Destructor Documentation

projection()

template<typename Coordinate , typename T = typename Coordinate::value_type>

cuproj::projection< Coordinate, T >::projection ( std::vector< operation_type > const & operations, projection_parameters< T > const & params, direction dir = direction::FORWARD )

inline

Construct a new projection object.

Parameters

operations	the list of operations to apply to coordinates
params	the projection parameters
dir	the default order to execute the operations, FORWARD or INVERSE

Definition at line 68 of file projection.cuh.

Member Function Documentation

get_device_projection()

template<typename Coordinate , typename T = typename Coordinate::value_type>

device_projection< Coordinate > cuproj::projection< Coordinate, T >::get_device_projection ( direction dir ) const

inline

Get a device_projection object that can be passed to device code.

This object can be used to transform coordinates on the device.

Note

The implementation is in detail::pipeline.

Parameters

dir	the direction of the transform, FORWARD or INVERSE.

Returns

the device projection

transform()

template<typename Coordinate , typename T = typename Coordinate::value_type>

template<class InputCoordIter , class OutputCoordIter >

void cuproj::projection< Coordinate, T >::transform ( InputCoordIter first, InputCoordIter last, OutputCoordIter result, direction dir, rmm::cuda_stream_view stream = rmm::cuda_stream_default ) const

inline

Transform a range of coordinates.

Template Parameters

CoordIter

the coordinate iterator type

Parameters

first	the start of the coordinate range
last	the end of the coordinate range
result	the output coordinate range
dir	the direction of the transform, FORWARD or INVERSE. If INVERSE, the operations will run in the reverse order of the direction specified in the constructor.
stream	the CUDA stream on which to run the transform
