What is the definition of direct evidence in surveying?

The definition of direct evidence in surveying refers specifically to evidence provided by a witness who directly observed an act. In the context of surveying, this type of evidence is critical because it is based on firsthand accounts, which are often the most reliable forms of information. For example, a surveyor who directly witnesses a boundary being marked or a previous survey being conducted can provide direct evidence of the location of property lines or features. This type of evidence helps to establish facts with a high degree of certainty, which is essential for making informed decisions in land surveying.

While circumstantial evidence and presumptive evidence can provide information, they are indirect and rely on inference rather than direct observation. Written agreements, although important, do not provide the immediate and observable proof that direct evidence does. This distinction is vital for understanding the hierarchy of evidence in legal and technical contexts within land surveying.
