Constructor Detail

ScaleParamThread

public ScaleParamThread(GISFrame gisFrame,
                        ScaleSurfParam ssp)

Calculates a given surface parameter over a range of scales.

Parameters:

gisFrame - GIS frame containing raster to process.

ssp - Multi-scale surface parameter to calculate.

Method Detail

doProcessing

public void doProcessing()

Performs the multi-scale processing. Adds the surface of average parameter values as a secondary raster map, and the surface of variation of the paramter as an unselected raster map. A newly created raster map containing the average parameter values over the range of scales for each cell in the DEM, and one containing the variation of those parameters are added to the GISFrame provided to the constructor. The average parameter surface can be retrieved directly via this class's getParamAverage() method, or by calling gisFrame.getRaster2();. The raster map containing the variation in parameter values can be retrieved via getParamVariation() or by calling gisFrame.getRasters() and selecting the last raster map added.

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