Can't find selected_algorithm in L2A GEDI elevation and canopy height dataset
Posted: Sat Dec 31, 2022 4:00 pm America/New_York
I am trying to extract ground elevation data from L2A GEDI "elevation and canopy height" dataset.
I managed to extract different variables, mostly elev_lowetreturn_a[N], corresponding lon/lat coordinates, and quality flags. I can't seem to find a way to extract the variable selected_algorithm, which is supposed to tell me which [N] I should actually be using, if I am not wrong. Moreover, I don't know to select different beams from the dataset.
I have been using the gedi_to_vector.py python script, which seems pretty neat - described here:

The typical command line I have been using is something like:
python gedi_to_vector.py ./ -variables [lon_lowestreturn_a1,lat_lowestreturn_a1,elev_highestreturn_a1,quality_flag_a1] -outFormat CSV
which should extract results for all of the eight beams; I mean, with no specification about which point correspond to which beam.
I do not care about the gedi_to_vector script - I can turn to whatever works to get what I need.
