Constructor Detail

TinToDemThread

public TinToDemThread(GISFrame gisFrame)

Prepares class for converting a TIN into DEM representation using planar interpolation.

Parameters:

gisFrame - GUI containing TIN and DEM.

TinToDemThread

public TinToDemThread(GISFrame gisFrame,
                      boolean doQuadratic)

Prepares class for converting a TIN into DEM representation. Can either use simple planar interpolation (gives triangular facets), or a smoother quadratic interpolation (can give overshoots and undershoots).

Parameters:

gisFrame - GUI containing TIN and DEM.

doQuadratic - Uses quadratic interpolation if true, otherwise planar.

Method Detail

getCommand

public LSCommand getCommand()

Reports the syntax required to allow convert TIN or vector into a raster via a scripting command.

Specified by:

getCommand in interface Scriptable

Returns:

Command syntax.

doCommand

public boolean doCommand(LSCommand command)

Creates a raster map representation of the vector map. If the vector map is a TIN, the result will be a DEM, otherwise a regular raster representation of the vector map.

Specified by:

doCommand in interface Scriptable

Parameters:

command - Command containing parameter values.

Returns:

True if the conversion is successful. If false, the details of the problem are reported to the gisFrame.

getReturnedObject

public Object getReturnedObject()

Returns a raster map holding the transformed object. If command has yet to be issued this will return null.

Specified by:

getReturnedObject in interface Scriptable

Returns:

New spatial object or null if problems converting or command has not yet been issued.

getGISFrame

public GISFrame getGISFrame()

Retrieves the GISFrame that can be used for storing multiple spatial objects.

Specified by:

getGISFrame in interface Scriptable

Returns:

GISFrame storing spatial objects.

doProcessing

public void doProcessing()

Convert the TIN into DEM representation. The resulting DEM can be retrieved via getDEM() or by calling gisFrame.getRaster1().

Note that this method will be called automatically if this is run as a threaded process (e.g. myTinToDemThread.start()). Alternatively it can be called directly as a non-threaded process.

Specified by:

doProcessing in class LSThread

GISFrame

getDEM

public RasterMap getDEM()

Retrieves the newly created DEM.

Returns:

New DEM, or null if process yet to take place.
