new export script to include comparison with 250m grid

File size: 3.8 KB
Line 
1"""
2Generates ascii grids of nominated areas -
3Input: sww file from run_perth.py
4       boundaries for grids from project.py
5Outputs: ascii grids of specified variables
6Stored in the 'outputs_dir' folder for respective .sww file
7
8Note:
9If producing a grid for the enitre extent cellsize should be greater than 30m
10If producing grids for inundation area resolution should be greater than mesh (ie ~22m)
