ilog.views.maps.format.dted
Class IlvRasterDTEDReader

java.lang.Object
  ilog.views.maps.raster.IlvRasterAbstractReader
      ilog.views.maps.format.dted.IlvRasterDTEDReader

All Implemented Interfaces:

IlvPersistentObject, IlvMapFeatureIterator, IlvMapReusableFeatureIterator

public class IlvRasterDTEDReader
extends IlvRasterAbstractReader
implements IlvPersistentObject

Reader of DTED files. Example of use:

   IlvRasterDTEDReader r = new IlvRasterDTEDReader();
   r.addMap(fileName);
  // create a datasource for the dted reader.
  IlvMapDataSource DTEDDataSource = IlvRasterDataSourceFactory.buildTiledImageDataSource(manager,r,true,true,null);
  // insert it in the manager's data source tree
  IlvMapDataSourceModel dataSourceModel = IlvMapDataSourceProperty.GetMapDataSourceModel(view.getManager());
  dataSourceModel.insert(DTEDDataSource);
  // start reading (recusively start all data sources of this model)
  dataSourceModel.start();
  // get the DTED  maplayer used to display that data source
  IlvMapLayer DTEDLayer = DTEDDataSource.getInsertionLayer();
  // insert it on the manager's map layer tree
  IlvMapLayerTreeModel ltm = IlvMapLayerTreeProperty.GetMapLayerTreeModel(view.getManager());
  ltm.addChild(null, DTEDLayer);

Constructor Detail

IlvRasterDTEDReader

public IlvRasterDTEDReader()

Default constructor

IlvRasterDTEDReader

public IlvRasterDTEDReader(IlvInputStream stream)
                    throws IlvReadFileException

Constructor from stream

Parameters:

stream -

Throws:

IlvReadFileException

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the attributes of a persistent object.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvRasterAbstractReader

Parameters:

stream - The output stream.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

addMap

public boolean addMap(String fileName)
               throws IOException

Adds a new DTED image.

Parameters:

fileName - Path pointing to one of the DTED files (.dt0,.dt1,.dt2)

Returns:

true. The color model is built through the use of a { @link IlvRasterElevationColorModelFactory}

Throws:

IOException - if the fileName is an unrecognized file.

addMap

public boolean addMap(URL url)
               throws IOException

Adds a new DTED image.

Parameters:

url - URL pointing to one of the DTED files (.dt0,.dt1,.dt2)

Returns:

true.

Throws:

IOException - if the url is an unrecognized file.

Since:

JViews 7.5

reload

public void reload(IlvThreadMonitoringData monitorInfo)

Given the state of the reader (how many images were read, coverage zone,...), the purpose of this method is to recreate all images from the original source. Note : this method should not rely on the list of IlvRasterProperties of the reader as they might not be saved when the theme only is saved.

Overrides:

reload in class IlvRasterAbstractReader

Parameters:

monitorInfo - Used to update task progress.

getCoordinateSystem

public IlvCoordinateSystem getCoordinateSystem()

Returns a WGS84 system.

Specified by:

getCoordinateSystem in interface IlvMapFeatureIterator

Returns:

The coordinate system, or null if the coordinate system is unknown.

See Also:

IlvMapFeatureIterator.getCoordinateSystem()

getInternalTransformation

public IlvMathTransform getInternalTransformation(int imageIndex)

Return the projection associated with the raster stored at the given index.

Specified by:

getInternalTransformation in class IlvRasterAbstractReader

Parameters:

imageIndex - The index of the raster.

Returns:

The projection that corresponds to the raster stored at the given index.

See Also:

IlvRasterAbstractReader.getInternalTransformation(int)

getProperties

public IlvFeatureAttributeProperty getProperties(int imageIndex)

Returns the feature properties to be associated with the image.

Specified by:

getProperties in class IlvRasterAbstractReader

Parameters:

imageIndex - The index of the image.

Returns:

The properties to be associated with the image.

See Also:

IlvRasterAbstractReader.getProperties(int)
