The datacube extension (and others, too, I think) use:
The unit of measurement for the data, preferably compliant to UDUNITS-2 units (singular).
Is this good enough? It's difficult to standardize here as people have so diverging needs. This field will be migrated to STAC core metadata in 1.1 (raster 2.0) so is not that relevant for the raster extension, but for core.
The current raster spec does not give much guidance about the
unit
field, and inconsistency in the field may make datasets less interoperable.As a concrete example, should a unit be
meter
ormetre
ormeters
orm
orcm
orkm
?It would be good to describe a best practice for this field. For example:
scale
field rather than SI prefixes
