oggm.Flowline

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

Initialize a Flowline

Parameters

the geometrical line of a oggm.Centerline

dxfloat

Grid spacing in pixel coordinates

map_dxfloat

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_idstr

The glacier’s RGI identifier

water_levelfloat
