oggm.core.flowline.Flowline¶

class oggm.core.flowline.Flowline(line=None, dx=1, map_dx=None, surface_h=None, bed_h=None, rgi_id=None, water_level=None)[source]¶

A Centerline with additional properties: input to the FlowlineModel

__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)

Methods

`__init__`([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.
