Member Function Documentation

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

pure virtual

Implemented in MetNoFimex::ProjectionImpl.

Referenced by ~Projection().

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

pure virtual

Implemented in MetNoFimex::ProjectionImpl.

virtual void MetNoFimex::Projection::convertFromLonLat ( std::vector< double > &  xVals, std::vector< double > &  yVals  ) const throw ( CDMException )

virtual

convert two vectors of values in the projection to latitude and longitude in degree. The earth ellipsoid will be the same as the input.

Parameters

xVals	longitude input in degree, output of the projection axis in meter or degree
yVals	latitude input in degree, output of the projection axis in meter or degree

Warning

the values will be converted in place

Referenced by ~Projection().

virtual void MetNoFimex::Projection::convertToLonLat ( std::vector< double > &  xVals, std::vector< double > &  yVals  ) const throw ( CDMException )

virtual

convert two vectors of values in the projection to latitude and longitude in degree. The earth ellipsoid will be the same as the input.

Parameters

xVals	input of the projection axis in meter or degree, output is longitude
yVals	input of the projection axis in meter or degree, output is latitude

Warning

the values will be converted in place

Referenced by ~Projection().

static boost::shared_ptr<Projection> MetNoFimex::Projection::create ( std::vector< CDMAttribute >  )

static

create a projection from some CDMAttributes

Referenced by ~Projection().

static boost::shared_ptr<Projection> MetNoFimex::Projection::createByProj4 ( const std::string &  projStr )

static

create a projection from a proj4 string

Referenced by ~Projection().

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

pure virtual

get the projection name

Implements MetNoFimex::CDMNamedEntity.

Implemented in MetNoFimex::ProjectionImpl.

Referenced by ~Projection().

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

pure virtual

Implemented in MetNoFimex::ProjectionImpl.

Referenced by ~Projection().

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

pure virtual

get the parts of the proj4 string defining the earth.

virtual

Comparison of two projections, implemented using the toString() function. This function does not guarantee that two projections are physically equal.

Referenced by ~Projection().

pure virtual

Implemented in MetNoFimex::ProjectionImpl.

Referenced by ~Projection().

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

pure virtual

get a string representation

Note

this should be implemented as unique as possible, i.e.
