A permanent marker installed on the land by a surveyor is called ______.

A permanent marker installed on land by a surveyor is referred to as a monument. In land surveying, a monument serves as a fixed reference point that helps define the boundaries of a parcel of land. Monuments can be physical objects such as stones, metal markers, or wooden posts placed at specific points to delineate property lines.

Understanding the other terms can provide additional clarity. "Metes" refers to the measured distances between specific points in a property's boundary, often described in terms of linear measurements such as feet or meters. "Bounds" deals with the direction and extent of the property lines, and is typically utilized in conjunction with metes. "A lot" usually refers to a plot of land or a section that has been subdivided and designated for sale or development.

In summary, a monument is essential for accurate land delineation, making it the correct term for a permanent marker used in surveying contexts.
