An additional density-based algorithm was run on all candidate bathymetry photons to determine a final classification; The “profile” and “stats” variables under the “/metadata” group were removed because they are not relevant to v2; An “atl24” variable under the “/metadata” group was added to capture the specific versioning information related to the new algorithm. This new variable will be used going forward to precisely capture the versioning information of the algorithms that are run; A “DatasetIdentification” subgroup was added to the “/metadata” group.
