polaris.mesh.spherical.coastline.rasterize_critical_transects

polaris.mesh.spherical.coastline.rasterize_critical_transects(critical_transects, lon, lat)

Rasterize critical land blockages and passages onto a lat-lon grid.

Parameters:

• critical_transects (CriticalTransects or None) – Critical land blockages and passages (a polaris.mesh.spherical.critical_transects.CriticalTransects object) to rasterize

• lon (numpy.ndarray) – The longitude coordinate in degrees

• lat (numpy.ndarray) – The latitude coordinate in degrees

Returns:

• land_blockages (numpy.ndarray) – A boolean mask of rasterized land blockages

• passages (numpy.ndarray) – A boolean mask of rasterized ocean passages
