Constructor Detail

SurfNetworkThread

public SurfNetworkThread(GISFrame gisFrame)

Initialises the surface network processing.

Parameters:

gisFrame - GIS frame containing rasters to process.

Method Detail

doProcessing

public void doProcessing()

Processes the raster DEM and surface feature layers extracting the surface network. Generatea a raster and vector map of the surface network (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 getFeatureNetworkRaster() and getFeatureNetworkVector() 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. mySurfaceNetworkThread.start()). Alternatively it can be called directly as a non-threaded process.

doProcessing in class LSThread
