Pin flags are commonly used in surveying to indicate the boundaries of small properties. They serve as visual markers that help surveyors delineate property lines, making it easier to identify the extents of a parcel of land during both the surveying process and for property owners or potential buyers. These flags are particularly useful in circumstances where the boundaries may not be clearly defined or visible due to vegetation or other obstructions. By marking the corners and edges of a property, pin flags help communicate and confirm the legal limits of ownership, which is essential in land disputes and development purposes.

In contrast, the other options pertain to different aspects of surveying. Reference points of interest may be marked using more permanent or substantial markers rather than pin flags. Measurements of elevation are commonly taken using leveling instruments or GPS, rather than being indicated by flags. Survey lines and angles usually involve the use of more exacting tools and methods, like theodolites or total stations, to establish precise measurements, rather than simple pin flags.
