Interpreting Compass Directions on Survey Plans
Survey plans utilize compass directions to illustrate the orientation of property lines and features relative to true north. Understanding how these directions are represented is crucial for interpreting the plan accurately. A north arrow, typically displayed on the map, indicates true north, serving as the reference point for all directional measurements. Bearings, expressed in degrees, are measured clockwise from north, specifying the direction of a line segment. For instance, a bearing of 90 degrees indicates a line running due east, while 180 degrees signifies a line pointing due south. The compass rose, a circular diagram showing the cardinal directions, may also be included to aid interpretation. However, the precise representation of compass directions can vary; some plans might use magnetic north instead of true north, requiring awareness of declination, the angle between true north and magnetic north. Correct interpretation of compass directions is critical for determining the location and orientation of property boundaries and other spatial elements. Moreover, understanding how compass directions relate to bearings is essential for accurately plotting and measuring distances on the plan. Familiarity with these conventions is indispensable for anyone interpreting survey data and understanding property boundaries. Paying close attention to the map’s legend and notation is crucial to ensure accurate interpretation of compass directions within the context of the specific survey.
