What is the responsibility of a surveyor when referencing "Grid North" in surveys?

When referencing "Grid North" in surveys, the surveyor's responsibility is to ensure that all angles are adjusted accordingly. Grid North is aligned with the grid system used in mapping and represents the north direction as depicted on a map. Because the Earth's magnetic north can vary due to magnetic declination and geographic location, surveys that rely on Grid North need to incorporate adjustments to maintain accuracy in positioning and angles. This ensures that the survey data aligns correctly with the grid, allowing for consistent interpretation and application across various mappings and plans.

In essence, proper adjustments to angles when dealing with Grid North enable surveyors to provide precise and reliable data, which is essential for construction, land division, and other surveying purposes. By ensuring all angles are adjusted accurately, the surveyor affirms the integrity of the surveying process and the validity of the resulting measurements.
