Calculate distances between placemarks; Calculate route (bearing) to the next placemark; Add distances, routes and/or coordinates to the placemarks description; Draw horizontal and/or vertical grids (equally spaced or not) Draw regular polygons around placemarks; Calculate path’s length/perimeter. Grid Bearing can be obtained by astronomical observations by applying Convergency. Can you calculate the coordinates and the length of this vector? To find the coordinates, translate the line segment one unit left and two units down. e 0° bearing means North, 90° bearing is East, 180° bearing is measured to be South, and 270°. 6733, 23167.
