A more thorough explanation:

Definition: A land boundary is a line or border that separates one piece of land from another. It is the legal and physical limit of a property.

Example: If you own a house, your land boundary is the line that separates your property from your neighbor's property. This line is usually marked by a fence, a wall, or a hedge.

Another example: A land boundary can also be a natural feature, such as a river or a mountain range, that separates two pieces of land.

The examples illustrate that a land boundary is a physical and legal limit that defines the extent of a property. It is important to know the land boundary to avoid disputes with neighbors and to ensure that you are using your property within the legal limits.
