What term describes a survey tape that includes minor graduations placed ahead of the zero point?

The term "add tape" refers to a survey tape that has minor graduations placed ahead of the zero point. This feature is particularly useful for surveyors as it allows for greater precision when making measurements. The minor graduations provide additional reference points that help in establishing accurate distances without having to move the tape away from the starting point.

Measuring tape is a more general term and does not specifically refer to this added feature. Survey line typically refers to a defined path or route along which surveys are conducted, rather than a specific type of tape. Flag tape is a type of marking tape often used to signal boundaries or reference points in the field, but it does not have the graduations that add tape provides. The definition and specific purpose of add tape make it the only correct answer in this context.
