Colorado Land Surveyor Practice Exam

A control corner is a specific point used in land surveying that establishes the boundaries of parcels of land. It serves as a reference point for determining the exact locations of property lines. This is crucial for legal descriptions of land and for the accurate mapping of properties. Control corners are established using precise measurements and techniques, making them fundamental for both public and private land surveys. The other options highlight various aspects of land and geography but do not accurately capture the primary function of a control corner in the context of surveying. For instance, while a reference point for navigation is important, it doesn't serve the same role as a control corner. Similarly, significant landmarks may be useful for orientation but are not precise measurements of property boundaries. Markers indicating land use regulations pertain to zoning and property use but do not define boundary locations. Thus, the essence of a control corner is its definitive role in determining the legal boundaries of land.
