gedidb.L2BBeam

class gedidb.L2BBeam(granule: granule_handler, beam: str, field_mapping: Dict[str, Dict[str, str]])

Represents a Level 2B (L2B) GEDI beam and processes the beam data. This class extracts geolocation, time, and elevation data, applies quality filters, and returns the filtered beam data as a dictionary.

__init__(granule: granule_handler, beam: str, field_mapping: Dict[str, Dict[str, str]])

Initialize the L2BBeam class.

Parameters:

• granule (Granule) – The parent granule object.

• beam (str) – The beam name within the granule.

• field_mapping (Dict[str, Dict[str, str]]) – A dictionary mapping fields to SDS names.

Methods

__init__(granule, beam, field_mapping)	Initialize the L2BBeam class.
apply_filter(data[, filters])	Apply a set of filters to the beam data.
build_virtual_dataset(name, shape, dtype[, ...])	Assemble a virtual dataset in this group.
clear()
copy(source, dest[, name, shallow, ...])	Copy an object or group.
create_dataset(name[, shape, dtype, data])	Create a new HDF5 dataset
create_dataset_like(name, other, **kwupdate)	Create a dataset similar to other.
create_group(name[, track_order])	Create and return a new subgroup.
create_virtual_dataset(name, layout[, fillvalue])	Create a new virtual dataset in this group.
get(name[, default, getclass, getlink])	Retrieve an item or other information.
items()	Get a view object on member items
keys()	Get a view object on member names
move(source, dest)	Move a link to a new location in the file.
pop(k[,d])	If key is not found, d is returned if given, otherwise KeyError is raised.
popitem()	as a 2-tuple; but raise KeyError if D is empty.
require_dataset(name, shape, dtype[, exact])	Open a dataset, creating it if it doesn't exist.
require_group(name)	Return a group, creating it if it doesn't exist.
setdefault(k[,d])
update([E, ]**F)	If E present and has a .keys() method, does: for k in E.keys(): D[k] = E[k] If E present and lacks .keys() method, does: for (k, v) in E: D[k] = v In either case, this is followed by: for k, v in F.items(): D[k] = v
values()	Get a view object on member objects
visit(func)	Recursively visit all names in this group and subgroups.
visit_links(func)	Recursively visit all names in this group and subgroups.
visititems(func)	Recursively visit names and objects in this group.
visititems_links(func)	Recursively visit links in this group.

file	Return a File instance associated with this object
id	Low-level identifier appropriate for this object
main_data	Retrieve the main data for the beam from the granule file.
n_shots	Get the number of shots in the beam.
