Detailed Description

ProjectionImpl is a next to complete implementation of Projection, storing all parameters as a vector<CDMAttribute>. Implementations only need to implement a constructor calling the ProjectionImpl("proj-name") and the method getProj4ProjectionPart()

Note

the implemented projection needs to get made visible in Projection::create() and Projection::createByProj4

Member Function Documentation

virtual void MetNoFimex::ProjectionImpl::addParameter ( CDMAttribute  attribute )

virtual

Implements MetNoFimex::Projection.

virtual void MetNoFimex::ProjectionImpl::addParameters ( std::vector< CDMAttribute >  attributes )

virtual

Implements MetNoFimex::Projection.

bool MetNoFimex::ProjectionImpl::addParameterToStream ( std::ostream &  outStream, const std::string &  name, std::string  replaceName = ""  ) const

protected

Add the numeric value of a parameter named name as replaceName to oproj, e.g. name = false_easting, replaceName = +x_0, sets "+x_0=... " Assume only one value at maximum

Parameters

outStream
name	the parameters name
replaceName	the name to use in the stream to the parameter, defaults to original name ("")

Returns

true if parameter found and set

virtual const std::string& MetNoFimex::ProjectionImpl::getName ( ) const

virtual

get the projection name

Implements MetNoFimex::Projection.

virtual std::vector<CDMAttribute> MetNoFimex::ProjectionImpl::getParameters ( ) const

virtual

Implements MetNoFimex::Projection.

virtual std::string MetNoFimex::ProjectionImpl::getProj4EarthString ( ) const

virtual

get the parts of the proj4 string defining the earth.

Implements MetNoFimex::Projection.

virtual std::ostream& MetNoFimex::ProjectionImpl::getProj4ProjectionPart ( std::ostream &  ) const

protectedpure virtual

add the pure projection parameters for proj4 to the stream, i.e. no earth definitions, and no +no_defs

Implemented in MetNoFimex::RotatedLatitudeLongitudeProjection, MetNoFimex::UnknownToFgdcProjection, MetNoFimex::AlbersConicalEqualAreaProjection, MetNoFimex::AzimuthalEquidistantProjection, MetNoFimex::LambertAzimuthalEqualAreaProjection, MetNoFimex::LambertConformalConicProjection, MetNoFimex::LambertCylindricalEqualAreaProjection, MetNoFimex::LatitudeLongitudeProjection, MetNoFimex::OrthographicProjection, MetNoFimex::StereographicProjection, MetNoFimex::VerticalPerspectiveProjection, MetNoFimex::MercatorProjection, and MetNoFimex::TransverseMercatorProjection.

virtual std::string MetNoFimex::ProjectionImpl::getProj4String ( ) const

virtual

get the proj4 string defined by the parameters. If a parameter named 'proj4' exists, that one will be used and all other parameters will be ignored.

Note

Implementors should not overwrite this method, but the protected getProj4ProjectionPart() method

Implements MetNoFimex::Projection.

virtual bool MetNoFimex::ProjectionImpl::isDegree ( ) const

virtual

check if the coordinates belonging to this projection are in degree (otherwise metrical)

Implements MetNoFimex::Projection.

static void MetNoFimex::ProjectionImpl::proj4GetEarthAttributes ( const std::string &  proj4String, std::vector< CDMAttribute > &  attrList  )

staticprotected

add the attributes describing the earth from a proj4-string to the outAttrs

Parameters

proj4String	string as used for proj4
attrList	output list of CDMAttributes

static bool MetNoFimex::ProjectionImpl::proj4ProjectionMatchesName ( const std::string &  proj4String, const std::string &  name  )

staticprotected

match the +proj= part of a proj4 string

virtual void MetNoFimex::ProjectionImpl::removeParameter ( std::string  paramName )

virtual

Implements MetNoFimex::Projection.

virtual std::string MetNoFimex::ProjectionImpl::toString ( ) const

virtual

get a string representation

Implements MetNoFimex::Projection.
