The north arrow on a Survey Map or Survey Plat is fundamental for interpreting the orientation of the map. It must correlate with the courses or bearings to provide an accurate representation of direction. Surveyors use the north arrow to indicate the true north or magnetic north, ensuring that anyone reading the map can understand how the property boundaries relate to the cardinal directions.

This correlation is essential for proper navigation and for understanding the relationships between the surveyed property and its surroundings. It also aids in assessing the layout of structures or features in relation to geographic north, which is important for zoning, planning, and other regulatory purposes.

Without a properly oriented north arrow, there could be significant confusion regarding the map's orientation, leading to misinterpretation of the survey data. Therefore, the north arrow's alignment with the courses and bearings is crucial for maintaining the integrity and usefulness of a survey map.
