__init__
(line=None, dx=1, map_dx=None, surface_h=None, bed_h=None, rgi_id=None, water_level=None)[source]¶ Initialize a Flowline
Parameters: - line :
shapely.geometry.LineString
the geometrical line of a
oggm.Centerline
- dx : float
Grid spacing in pixel coordinates
- map_dx : float
DEM grid spacing in meters
- surface_h: :py:class:`numpy.ndarray`
elevation [m] of the flowline grid points
- bed_h: :py:class:`numpy.ndarray`
elevation[m] of the bedrock at the flowline grid points
- rgi_id : str
The glacier’s RGI identifier
- water_level : float
The water level (to compute volume below sea-level)

([line, dx, map_dx, surface_h, …])Initialize a Flowline has_ice
()set_apparent_mb
(mb[, mu_star])Set the apparent mb and flux for the flowline. set_flows_to
(other[, check_tail, to_head])Find the closest point in “other” and sets all the corresponding attributes. set_line
(line)Update the Shapely LineString coordinate. to_dataset
()Makes an xarray Dataset out of the flowline. Attributes
