Computing the ratio of linear error of closure of a traverse from its length and error of closure 4. Computing the latitude and departure from the corrected angles  and  distances 6-47. Plane coordinates describe the location of a point in what manner? 1. By a distance north or south and east or west from a point of  origin 2. By bearing north or south and east or west from a point of origin 3. By bearing and distance from a point  of  origin 4. By the line of sight from a point  of  origin Learning  Objective:  Compute coordinates  from  latitude  and departure;  compute  latitude  and departures  from  coordinates.
