What is the term for land that has not been officially surveyed and is still in the public domain?

The term for land that has not been officially surveyed and is still in the public domain is "vacancy." This designation reflects the status of the land being unclaimed and uncharted for formal use, often indicating that it has not been allocated or designated for specific legal possession or development.

Vacant land can still belong to the public domain and may be available for future surveying, development, or use. It is distinct from surveyed land, which has undergone formal measurement and mapping, establishing legal boundaries and ownership. Therefore, vacancy emphasizes the unprocessed state of the land within the broader context of land management and regulation.

The other terms listed do not accurately represent this concept. While "unbounded land" and "free land" suggest a lack of restrictions, they do not specifically refer to the absence of a survey or the public domain, and "surveyed land" implies that the land has been measured and has established boundaries.
