class
oggm.
Flowline
(line=None, dx=1, map_dx=None, surface_h=None, bed_h=None, rgi_id=None)[source]¶ Common logic for different types of flowlines used as input to the model

__init__
(self, line=None, dx=1, map_dx=None, surface_h=None, bed_h=None, rgi_id=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
- line :
Methods
__init__
(self[, line, dx, map_dx, …])Initialize a Flowline set_apparent_mb
(self, mb[, mu_star])Set the apparent mb and flux for the flowline. set_flows_to
(self, other[, check_tail, …])Find the closest point in “other” and sets all the corresponding attributes. set_line
(self, line)Update the Shapely LineString coordinate. to_dataset
(self)Makes an xarray Dataset out of the flowline. Attributes
area_km2
area_m2
flows_to_indice
Indices instead of geometry inflow_indices
Indices instead of geometries length_m
normals
List of (n1, n2) normal vectors at each point. surface_h
Needed for overriding later thick
Needed for overriding later volume_km3
volume_m3
widths
Compute the widths out of H and shape -
