2 | Generates ascii grids of nominated areas - |
---|
3 | Input: sww file from run_perth.py |
---|
4 | boundaries for grids from project.py |
---|
5 | Outputs: ascii grids of specified variables |
---|
6 | Stored in the 'outputs_dir' folder for respective .sww file |
---|
7 | |
---|
8 | Note: |
---|
9 | If producing a grid for the enitre extent cellsize should be greater than 30m |
---|
10 | If producing grids for inundation area resolution should be greater than mesh (ie ~22m) |
