mod_filter.compute_median_dx(dataset)

mod_filter.distance(lon0, lat0, lon1, lat1)

Compute distance between points from each line.

Parameters:

• lon0 (float)

Returns:

distance (in m)

Return type:

array

mod_filter.lanczos_filter(wave_length, x, z, order=1)

Apply a lanczos filter on z field

Parameters:

• wave_length (float) – half window where apply lanczos in x units

• x (array) – must be growing for each track but could be irregular

• z (array) – field to apply lanczos

mod_filter.median_filter(half_window, x, z)

Apply a median filter on z field

Parameters:

• half_window (float) – half window where apply median

• x (array) – must be growing for each track but could be irregular

• z (array) – field to apply median
