          jwo.landserf.process.PeakClassificationThread

All Implemented Interfaces:

JWInterruptionListener, Runnable

public class PeakClassificationThread

extends LSThread

Creates a new raster identifying peaks from a given DEM. This requires parameters such as minimum height and minimum drop to be supplied allowing Munros, Corbetts, Hewitts, Marilyns etc. to be identified.

Constructor Detail

PeakClassificationThread

public PeakClassificationThread(GISFrame gisFrame,
                                float minHeight,
                                float minDrop,
                                boolean doPeakedness,
                                boolean doSummits,
                                boolean doHierarchy)

Classifies the DEM according to the peak classification parameters.

Parameters:

gisFrame - GISFrame holding DEM to process.

minHeight - Minimum height of peak.

minDrop - Minimum drop surrounding peak.

doPeakedness - Peakedness calculation performed if true.

doSummits - Calculates vector summit locations if true.

Method Detail

doProcessing

public void doProcessing()

Processes DEM stored as the primary raster in the GISFrame provided to the constructor and creates a raster map of peaks. Depending on options given to the constructor, can also generate a raster map of nested peak catchments, a raster map representing fuzzy peak extents and a vector map containing summits and drops. The newly created raster map containing the peaks is added to the GISFrame provided to the constructor as a secondary raster. This can be retrieved directly via this class's method getPeakMap(), or by calling gisFrame.getRaster2();. If summit vector map output has been chosen, the newly created vector map containing the summits and drops is added to the GISFrame provided to the constructor as a primary vector map. This can be retrieved directly via this class's method getSummitMap(), or by calling gisFrame.getVector1();. If the fuzzy peak or peak hierarchy options are selected, these raster maps can be retrieved directly via this class's getFuzzyPeakMap() and getPeakHierarchyMap() methods. Alternatively, they can be retrieved via the GISFrame's getRasterMaps() method (the last one/two map(s) added).

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