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, gdir=None)

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)

Initialize a Flowline

Parameters:

lineshapely.geometry.LineString

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

The water level (to compute volume below sea-level)

Methods

__init__([line, dx, map_dx, surface_h, ...])	Initialize a Flowline
has_ice()
reset_flux()
set_apparent_mb(mb[, is_calving])	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_diagnostics_dataset()	Makes an xarray Dataset out of the flowline.
to_geometry_dataset()	Makes an xarray Dataset out of the flowline.
