But only a person can determine a boundary--defining the land that is registered to be surveyed. According to regulations, both neighbors must be present. If someone is not clear what their boundary is, the surveyors must consult the original survey maps to help in identifying the boundary.
但是界址認定只能由人解決，按規定鄰界雙方都要在場，如果有人不清楚自身的界址，測量員還要參照原有地籍圖協助指界。
