Latitude is the projection of the line lying in the north-south direction or in the x-axis. Departure is the projection of the line lying in the east-west direction or in the y-axis.
Latitude and departure in surveying are two coordinates that are used to map a particular area or land feature. Latitude is the angle formed by a line drawn from the center of the earth to the surveyed point, while departure is the horizontal distance between two points on a map. Together, these coordinates allow surveyors to accurately measure and map an area.
Departure in surveying is a measure of how far a survey line deviates from a reference line. It is calculated by subtracting the length of the reference line from the surveyed line, and is expressed as either an absolute distance or a percentage.
Departure is used to assess the accuracy of a survey and ensure that the survey line stays within the boundaries of the area being measured.
