project(geometry_) click to toggle source

Projects the given geometry into the projected coordinate space, and returns the projected geometry. Returns nil if this factory does not support a projection. Raises Error::InvalidGeometry if the given geometry is not of this factory.

# File lib/rgeo/geographic/factory.rb, line 288
def project(geometry_)
  return nil unless @projector && geometry_
  unless geometry_.factory == self
    raise Error::InvalidGeometry, 'Wrong geometry type'

projection_factory() click to toggle source

Returns the factory for the projected coordinate space, or nil if this factory does not support a projection.

# File lib/rgeo/geographic/factory.rb, line 277
def projection_factory
  @projector ? @projector.projection_factory : nil
end

projection_limits_window() click to toggle source

Returns a ProjectedWindow specifying the limits of the domain of the projection space. Returns nil if this factory does not support a projection, or the projection limits are not known.

# File lib/rgeo/geographic/factory.rb, line 328
def projection_limits_window
  if @projector
    unless defined?(@projection_limits_window)

    end
    @projection_limits_window
  else
    nil
  end
end

projection_wraps?() click to toggle source

Returns true if this factory supports a projection and the projection wraps its x (easting) direction. For example, a Mercator projection wraps, but a local projection that is valid only for a small area does not wrap. Returns nil if this factory does not support or a projection, or if it is not known whether or not it wraps.

# File lib/rgeo/geographic/factory.rb, line 318
def projection_wraps?
  @projector ? @projector.wraps? : nil
end

Returns the srid reported by this factory.

# File lib/rgeo/geographic/factory.rb, line 262
def srid
  @srid
end

unproject(geometry_) click to toggle source

Reverse-projects the given geometry from the projected coordinate space into lat-long space. Raises Error::InvalidGeometry if the given geometry is not of the projection defined by this factory.

# File lib/rgeo/geographic/factory.rb, line 302
def unproject(geometry_)
  return nil unless geometry_
  unless @projector && @projector.projection_factory == geometry_.factory
    raise Error::InvalidGeometry, 'You can unproject only features that are in the projected coordinate space.'
  end
  @projector.unproject(geometry_)
end
