Method Detail

slopeRisk

public java.util.TreeMap slopeRisk(analysis.java.Raster slope)

Converts a slope Raster to a TreeMap containing cell id and risk value for cell id

Parameters:

slope - a Raster object containing slope in degrees

Returns:

risktree a TreeMap containing cell id and risk value for cell id

novegRisk

public java.util.TreeMap novegRisk(java.util.ArrayList list,
                                   java.util.TreeMap tree)

Creates a TreeMap containing risk values for cells, masked out by the NDVI index and considered risk-prone

Parameters:

list - an ArrayList of non-vegetated cells, derived from NDVI index

tree - a TreeMap containing cell id and risk value for cell id

Returns:

a TreeMap containing non-vegetated risk-pron cells and their risk values

basinRisk

public java.util.TreeMap basinRisk(java.util.ArrayList list,
                                   java.util.TreeMap tree)

Creates a TreeMap containing basin id and risk value for basin as a whole

Parameters:

list - an ArrayList containing all cells for each basin

tree - a TreeMap containing non-vegetated and risk-prone cells and their value

Returns:

a TreeMap containing basin id and risk value for basin as a whole

riskCellsInBasinToRaster

public analysis.java.Raster riskCellsInBasinToRaster(java.util.ArrayList list,
                                                     java.util.TreeMap map,
                                                     analysis.java.Raster raster)

Creates a Raster object with non-vegetated risk-prone cells within basins

Parameters:

list - an ArrayList containing all cells for each basin

map - a TreeMap containing risk-prone cells, based on their slope

raster - the Raster object to be poulated

Returns:

a Raster object containing cells within basins that are risk-prone
