Input vegetation reclassification map:

There are many classes in the original vegetation. To derive the target vegetation classes described in the Standard (1: Forest, 2: Woodland, 3: Shrubland, 4: Scrub, 5: Mallee/Mulga, 6: Rainforest, 7: Grassland/Tussock moorland.), the remap string is defined as: “1 6;2 1;3 1;4 1;5 13 2;14 5;15 18 3;19 22 7;23 4;24 25 NODATA;26 4;27 28 NODATA;29 4;30 1;31 2;32 5;99 NODATA”.

Output path:

The example output path is C:\github\bal\examples\output.

FDI value:

Default value 80 is selected.

Extent:

Default is selected.

After all input parameters are defined, the fields in the BAL calculation window are all populated. See Fig. 12.

Example input parameters within BAL calculation window.

Process

After clicking the OK button in the above window, the calculation starts running with the progress displayed in a pop-up window. When it finishes successfully, the pop-up window looks like Fig. 13.

Example pop-up window when the calculation finishes.
