Class LatLon

java.lang.Object

ucar.nc2.dataset.transform.AbstractTransformBuilder

ucar.nc2.dataset.transform.LatLon

All Implemented Interfaces:

HorizTransformBuilderIF

public class LatLon
extends AbstractTransformBuilder
implements HorizTransformBuilderIF

This grid mapping defines the canonical 2D geographical coordinate system based upon latitude and longitude coordinates on a spherical Earth. It is included so that the figure of the Earth can be described.

Method Detail

getTransformName

public java.lang.String getTransformName()

Description copied from interface: HorizTransformBuilderIF

Get the Transform name. Typically this is matched on by an attribute in the dataset.

Specified by:

getTransformName in interface HorizTransformBuilderIF

Specified by:

getTransformName in class AbstractTransformBuilder

Returns:

name of the transform.

makeCoordinateTransform

public ProjectionCT makeCoordinateTransform(AttributeContainer ctv,
                                            java.lang.String geoCoordinateUnits)

Description copied from interface: HorizTransformBuilderIF

Make a ProjectionCT from a Coordinate Transform Variable. A ProjectionCT is just a container for the metadata, the real work is in the ProjectionImpl

Specified by:

makeCoordinateTransform in interface HorizTransformBuilderIF

Parameters:

ctv - the coordinate transform variable.

geoCoordinateUnits - the geo X/Y coordinate units, or null.

Returns:

ProjectionCT
