Latitudes & Departures: ΔN and ΔE, Linear Misclosure, Precision 1 : x and an Accuracy Class
This lesson is part of the course
In this lesson
You split every leg into its latitude ΔN and departure ΔE, add them up, turn the leftovers into the linear misclosure, express it as a precision 1 : x and classify the traverse with a fictional accuracy table.
