The Reference Elevation Model of Antarctica v2, this index is a set of tile identifiers and geographic extents with links to the s3 STAC ('s3url'), the tarball sources ('fileurl'), and the polygon of the tile and other information.
This is preserved as provided in the mosaic index Geopackage 'REMA_Mosaic_Index_v2_2m', but we also augment this with the various cog sources (layers provided in the tarballs, also available at these COG urls) and the extent of each in 'remav2_mosaic_index'.
The function remav2_index() returns the remav2_mosaic_index as a convenience.
