ucar.nc2.ui.gis.GisFeatureRenderer

ucar.nc2.ui.gis.GisFeatureRendererMulti

ucar.nc2.ui.gis.shapefile.EsriShapefileRenderer

All Implemented Interfaces:

Renderer

public class EsriShapefileRenderer
extends GisFeatureRendererMulti

Provides a convenient interface to ESRI shapefiles by creating lists of ucar.unidata.gis.AbstractGisFeature. Java2D Shape or VisAD SampledSet objects can be created from these.

Method Detail

factory

public static EsriShapefileRenderer factory(String filename)

Use factory to obtain a EsriShapefileRenderer. This caches the EsriShapefile for reuse.

Implementation note: should switch to weak references.

factory

public static EsriShapefileRenderer factory(String key,
                            InputStream stream)
