merge landmass and planetary landmass

• http://purl.obolibrary.org/obo/ENVO_01001782 Landmass: A large continuous area of land, either surrounded by sea or contiguous with another landmass. [ https://en.wiktionary.org/wiki/landmass ]

currently landmass has a single is-a child (planetary landmass) and single part-of child (roadside)

landmass already inherits the property of being part-of some astronomical body:

So I suppose we might want to retain a class for asteroid landmasses or landmasses of stars. If so siblings should be explicitly populated, and roadside should be migrated to be a part of the more specific planetary landmass (unless we really want to have parallel versions of all structures in ENVO for asteroids and stars)

But really, I think it is good to keep things as simple and possible and remove distinctions that are not useful - merging landmass and planetary landmass is simple and I don't think obstructs any use case for ENVO

I also think landmass/planetary landmass are missing subclasses. See:

• #1258

agree. I think its unlikely that the concept of 'land' would be useful on astronomical bodies that do not have water bodies.

The terms definitions are currently:

land

A surface layer of an astronomical body which is primarily composed of solid material and is not covered by oceans or other bodies of water.

landmass

A large continuous area of land, either surrounded by sea or contiguous with another landmass.

I guess there might be an argument for keeping the latter if we can clearly explain the subdivision and why it's different then the parent? I'm not convinced there is a strong differentia here, so I'd be in favor of deprecating the current landmass term, and making landmass the alternative or primary label for the current land class.

[smrgeoinfo]

land is a mass noun (how many 'lands' doesn't make sense' landmass is an object (how many landmassess' makes better sense)

landmass has constituent 'land'

Thanks @smrgeoinfo

I misread the above Chris was saying

merging landmass and planetary landmass

landmass def:

A large continuous area of land, either surrounded by sea or contiguous with another landmass.

planetary landmass def:

A landmass which is part of a planet.

As @smrgeoinfo alluded to earlier if landmasses are always on a planet then there would be no need for planetary landmass. Is that always true?
