Maps a "regions" dataset onto a user provided land/sea mask or grid
Usage:
-----
mapped,found = generateSurfaceTypeByRegionMask(mask,sftbyrgn=None,sftbyrgnmask=None,regions=None,maximum_regions_per_cell=4,extend_up_to=3,verbose=True)
Input:
-----
mask User provided land/sea mask (100/0) or grid (the land/sea mask will be generated automagically) which will be mapped using the "sftbyrgn" internal dataset (will generate a land/sea mask for you)
sftbyrgn Mask you wish to map onto your grid (if None uses internal "sftbyrgn" dataset (old ezget type))
sftbyrgnmask Land/sea mask for sftbyrgn (or a number specifying value limits for sftbyrgn which indicates land/sea threshold (greater values are land) - see URL below for integer region map)
regions Numbers from sftbyrgn array that you want to map onto mask (integers from 201-222)
maximum_regions_per_cell Maximum number of regions considered for a single cell
extend_up_to How many grid cells around a cell can we extend to identify a guess
verbose Prints to the screen what's going on (default is True)
Output:
-----
mapped Mapped input grid/mask using provided (or default) regions - sftbyrgn -> user provided grid/mask
found Matrix containing number of regions matched for each output cell
Notes:
-----
- More detailed information, including a region map and tabulated region numbers are available from http://www-pcmdi.llnl.gov/publications/pdf/34.pdf
