Grid generation:
# create a NZ grid at 0.1 degree spacing
nz_grid = Grid.for_polygon(0.1, Regions.NZ_SMALL.load())Grid operations:
grid_c = grid_a.union(grid_b)
grid_d = grid_c.difference(grid_e)
# set operations also work with GeoDataFrame objects
grid_f = grid_d.difference(Regions.WLG.load())Grid plotting:
plot = Plot()
plot.add_geoDataFrame(Regions.NZ.load())
plot.add_geoDataFrame(Regions.WLG.load())
plot.add_grid(grid)
plot.show()Visual diff:
# show a visual diff of the hutt and WLG grids
diff_grids("hutt_0.1.csv", "WLG_0.1.csv")IO:
write_grid(nz_grid, "NZ_0.1.csv")
grid = load_grid("NZ_0.1.csv")This package was created with Cookiecutter and the waynerv/cookiecutter-pypackage project template.
