Class GeoTiffGeoreferencing

java.lang.Object
org.gvsig.basicformats.impl.AbstractFormatFile
org.gvsig.basicformats.impl.DefaultWLDFile
org.gvsig.fmap.dal.file.tiff.GeoTiffGeoreferencing
All Implemented Interfaces:
org.gvsig.basicformats.FormatFile, org.gvsig.basicformats.WLDFile
public class GeoTiffGeoreferencing extends org.gvsig.basicformats.impl.DefaultWLDFile
Clase de utilidad para poblar un objeto IIOMetadata de ImageIO con las etiquetas (tags) de georreferenciacion estandar de GeoTIFF.

Esta clase encapsula la complejidad de la manipulacion del arbol DOM de los metadatos nativos de ImageIO para el formato TIFF.

Flujo de trabajo:

  1. Instanciar la clase.
  2. Usar setValue(WorldGeoreferencing) para establecer los parametros geometricos.
  3. Llamar a populateMetadata(IIOMetadata, Projection) para inyectar las etiquetas GeoTIFF en el objeto de metadatos proporcionado.
