1. Offset in Surveying - Offset in surveying refers to a perpendicular distance from a main survey line or object to a point or feature of interest. Offsets are used to accurately measure and locate features that are not directly accessible or visible from the main survey line.
2. Degree of precision in measuring offsets - The degree of precision in measuring offsets depends on the accuracy of the measuring instrument used and the skill of the surveyor. In general, more precise offsets require more accurate instruments and more experienced surveyors.
3. Limiting length of offset - The limiting length of an offset is determined by the accuracy of the measuring instrument and the skill of the surveyor. A longer offset will result in a greater margin of error, so the limiting length of an offset will depend on the required degree of precision for the survey.
For example, if a high degree of precision is required, the surveyor may choose to use a more accurate measuring instrument and limit the offset length to a shorter distance. On the other hand, if a lower degree of precision is acceptable, the surveyor may use a less precise instrument and allow for longer offsets.
In general, it is important for surveyors to carefully consider the degree of precision required for their survey and to choose the appropriate instruments and methods for measuring offsets accordingly.
