What legal term encompasses both ownership of land and the space above it?

The term that encompasses both ownership of land and the space above it is "real property rights." Real property rights refer to the legal rights associated with owning real estate, which include not just the physical ground (the surface) but also the airspace above it and any structures that may be constructed on it. Essentially, real property rights are a comprehensive term that encompasses all aspects of ownership.

Surface rights are limited to the land itself, while air rights specifically pertain to the rights to use the airspace above a property. Land use rights typically relate to how the land may be used under zoning laws and other regulations. Therefore, while other terms focus on specific aspects of property ownership, real property rights accurately captures the full scope of ownership over both the land and the airspace above it.
