Method Detail

getDefaultDataDirectory

public static java.lang.String getDefaultDataDirectory()

Returns a default data directory

getBasicGridInfo

public static double[] getBasicGridInfo(java.io.File gridFile)

Returns a double[] of grid information where; [0] = (double) ncols; [1] = (double) nrows; [2] = xllcorner; [3] = yllcorner; [4] = cellsize; [5] = noDataValue if it exists or Double.NEGATIVE_INFINITY otherwise

Parameters:

gridFile - The File of the grid.

isImageWriterAvailable

public static boolean isImageWriterAvailable(java.lang.String writerType)

Returns true if writerType is available

Parameters:

writerType - - usually a well known text String for an image type

generateGamInput

public static void generateGamInput(java.io.File gamInputFile,
