According to `gdalinfo`, MOD021KM (and MYD021KM for the matter), list identical bands under two different subdatasets (SDSes).
For example, SDS 3 (see `gdalinfo`'s report on it https://gitlab.com/thermopolis/public/code/-/snippets/2021406) and SDS 24 (see `gdalinfo`'s report on it https://gitlab.com/thermopolis/public/code/-/snippets/2021407), both contain essentially the same data/bands. The obvious differences between the two SDSes are the descriptive name (SDS 3 contains the characteristic, for this product, word 'SWATH') and the set of ground control points (GCP) (SDS 24 does not list any GCPs along). I've search in every related official document I can find on-line about MOD021KM products. I can't trace anything related to my question so far (see for example: - https://ladsweb.modaps.eosdis.nasa.gov/filespec/MODIS/61/MOD021KM - https://mcst.gsfc.nasa.gov/sites/default/files/file_attachments/M1054E_PUG_2017_0901_V6.2.2_Terra_V6.2.1_Aqua.pdf - https://mcst.gsfc.nasa.gov/sites/default/files/file_attachments/MODIS_L1B_ATBD_ver8_finalupload.pdf (although not the document that would expectedly contain details about the subdatasets in MOD02 products) ). Panoply (https://www.giss.nasa.gov/tools/panoply/), however, contains only once the set of Emissive bands at 1KM, and the same for the rest of data (see https://i.imgur.com/llGYVfo.png). What is the difference between the two SDSes?
