1. General

Forcing closure means to take an open link traverse, Figure I-1, and create a closed loop traverse by connecting the end points.


Figure J-1
Open link traverse

While this does result in a perfectly closed traverse it cannot account for any errors in the original open link. Forcing closure is commonly applied to initially map a property description whose last course reads similarly to "thence back to the point of beginning." A description like this is open since it does not specify length or direction of the closing line.
