public AbstractGisFeature()

Method Detail

getBounds2D

public abstract Rectangle2D getBounds2D()

Description copied from interface: GisFeature

Get the bounding box for this feature.

Specified by:

getBounds2D in interface GisFeature

Returns:

rectangle bounding this feature

getNumPoints

public abstract int getNumPoints()

Description copied from interface: GisFeature

Get total number of points in all parts of this feature.

Specified by:

getNumPoints in interface GisFeature

Returns:

total number of points in all parts of this feature.

getNumParts

public abstract int getNumParts()

Description copied from interface: GisFeature

Get number of parts comprising this feature.

Specified by:

getNumParts in interface GisFeature

Returns:

number of parts comprising this feature.

getShape

public Shape getShape()

Convert this GisFeature to a java.awt.Shape, using the default coordinate system, mapping gisFeature(x,y) -> screen(x,y). LOOK STILL HAVE TO crossSeam()

Returns:

shape corresponding to this feature.

getProjectedShape

public Shape getProjectedShape(ucar.unidata.geoloc.Projection dataProject,
                               ucar.unidata.geoloc.Projection displayProject)

Convert this GisFeature to a java.awt.Shape. The data coordinate system is in the coordinates of dataProject, and the screen is in the coordinates of displayProject. So: displayProject.latLonToProj( dataProject.projToLatLon(gisFeature(x,y))) -> screen(x,y).

Parameters:

dataProject - data Projection to use.

displayProject - display Projection to use.

Returns:

shape corresponding to this feature
