Method Detail

getInverseDistance2dGrid

public java.util.Vector getInverseDistance2dGrid(java.util.Vector gridVec,
                                                 java.lang.String data,
                                                 java.lang.String outFile,
                                                 float weight,
                                                 float searchRadius)

This is the interpolation function for this class, it does an Inverse Distance Weighted (IDW) Interpolation, using a user-defined weight coefficient, and serach radius.

Parameters:

gridVec - Vector -- a raster grid with an x, y, p, i, j structure

data - String -- the datafile

outFile - String -- the output file

weight - float -- the weight to be used for the interpolation, the smaller this value (or closer to 1) the smoother the grid, the larger the value the better the fit to the data. Typically, for geological data a value of 2 is used and for biological data 1.2 is commonly used.

searchRadius - float -- the lateral search direction -- if a grid cell has no corresponding data within the search no interpolation on that cell is done

Returns:

Vector -- the raster grid as a vector with the structure: x, y, value, i, j

getColumnToken

public java.lang.String getColumnToken(java.lang.String s,
                                       int tokenPosition)

utility method that returns a column value from a string that contains multiple tokens

Parameters:

string - -- the string to tokenize

tokenPosition - -- the location in the string to get

main

public static void main(java.lang.String[] args)

execute

public void execute(java.lang.String datafile,
                    java.lang.String outFile,
                    float xmin,
                    float xmax,
                    float ymin,
                    float ymax,
                    float dx,
                    float dy,
                    float nullval,
                    float weight,
                    float searchRadius)
