ocmw.domain.bathyTools.load_bathy(bathyfile, boffsets=[0.0, 0.0, 0.0])

Load bathymetry data from ASCII .xyz or.csv files, or netCDF files

Parameters:

• bathyfile (str) – Full path and name to the bathymery data file.

• boffsets (list, float, optional) – Translation offsets if required. The default is [0.0,0.0,0.0].

Returns:

bathy (TYPE) – DESCRIPTION.

ocmw.domain.bathyTools.bathy_msl_offset(bathyfile, offset, outfile, delimiter=',', headerSkip=0)

Function for adding MSL correction to ASCII bathymetr data. Currently only works for *.xyz and *.csv files.

Parameters:

• bathyfile (str) – Full path and filename of ASCII bathymetry data file.

• offset (float) – Offset in m to be applied to correct bathymetry data to MSL.

• outfile (str) – Full path and filename of output data file for corrected bathymetry.

• delimiter (str, optional) – Delimiter used in ASCII file. The default is ‘,’.

• headerSkip (int, optional) – Number of header lines to copy and skip. The default is 0.

Returns:

None.

ocmw.domain.bathyTools.interp_bathy(nodes, bathy, radius)

Interpolation of bathymetry data onto nodel nodes.

Parameters:

• nodes (numpy.ndarray, float) – Mesh node coordinates [x,y].

• bathy (numpy.ndarray, float) – Bathyemtry data [x,y,z].

• radius (float) – Radius of influence for interpolation.

Returns:

z (numpy.array, float) – Bathymetry values at node locations.
