When establishing corners, what is the primary source of evidence a surveyor should rely on?

The primary source of evidence a surveyor should rely on when establishing corners is physical monuments and historical records. These elements provide the most reliable and legally recognized evidence of property boundaries.

Physical monuments, such as stakes, concrete markers, or other substantial markers placed at specific locations, serve as tangible points that can be measured and verified in the field. Historical records, including previous surveys, property deeds, and land grants, contain documented evidence of boundary descriptions, which can be compared and corroborated with the physical monuments.

Relying solely on GPS data, while useful for providing accurate coordinates, does not account for the historical context and established boundaries indicated by physical monuments and historical documents. Similarly, recent satellite imagery can provide a broad view of the land but lacks the precision and legal validation that monuments and records offer. Eyewitness accounts, although they might provide useful contextual information, are not reliable as they can vary widely in accuracy and can be influenced by personal perceptions. Thus, physical monuments and historical records stand as the cornerstone of establishing property corners effectively and accurately.
