What is meant by "Written Evidence" in land surveying contexts?

In land surveying contexts, "Written Evidence" refers to documentary proof found in public records. This type of evidence is essential as it provides official documentation regarding land ownership, boundaries, easements, and other legal matters related to real property. These documents may include deeds, titles, land surveys, and government records that establish property rights and show the historical context of land use. Situating survey work within the existing legal framework requires relying on these public records, as they are authoritative sources that can help to resolve disputes or confirm details about a property.

The other options do not fit the definition of "Written Evidence" as precisely. Verbal agreements, while they can be significant in certain contexts, lack the formality and security provided by written documents. Drawings and sketches made by surveyors represent the technical data and interpretation of a survey but are not the legal written evidence that public records offer. Technical specifications for land use detail how land can be utilized but do not constitute evidence of ownership or rights in a legal sense as documented records do.
