Returns a named character vector of columns for the given product.
Names are the short user-facing column names (used in the columns
argument of sl_read()). Values are the full HDF5 dataset paths.
Arguments
- product
Character. One of:
GEDI:
"L1B","L2A","L2B","L4A","L4C"ICESat-2:
"ATL03","ATL06","ATL07","ATL08","ATL10","ATL13","ATL24"
- set
Character. Which column set to return:
"all"(default): every column in the registry, including geophysical corrections, instrument details, and pool columns."default": a curated subset of commonly useful science variables, quality flags, and context columns. This is whatsl_read()returns whencolumnsis not specified.
