Constructor Detail

SurfaceFeatureThread

public SurfaceFeatureThread(GISFrame gisFrame,
                            float minDrop)

Classifies the DEM into surface features according to the given relative drop/climb.

Parameters:

gisFrame - GISFrame holding DEM to process.

minDrop - Minimum drop/climb surrounding feature.

Method Detail

doProcessing

public void doProcessing()

Processes DEM and classifies surface features. Generatea a raster and vector map of surface features (pits, peaks, passes, ridges and channels). The newly created raster and vector maps are added to the GISFrame provided to the constructor as a secondary raster and primary vector respectively. These can be retrieved directly via this class's method getSurfaceFeatures() and getFeatureNetwork() methods, or by calling gisFrame.getRaster2(); abd gisFrame.getVectorMap1().

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

Specified by:

doProcessing in class LSThread

footprintReceived

public void footprintReceived(Footprint fp)

Responds to a mouse-selected location by calulating the local surface network from that position.

Specified by:

footprintReceived in interface FootprintListener

Parameters:

fp - Footprint broadcast.

getSurfaceFetures

public RasterMap getSurfaceFetures()

Retrieves the newly created raster map representing surface features.

Returns:

Surface feature raster, or null if problem or process yet to take place.

getSurfaceNetwork

public VectorMap getSurfaceNetwork()

Retrieves a newly created surface feature network.

Returns:

Vector map containing surface feature network, or null if problem or process yet to take place.
