4. Summary

A link traverse requires a few variations on the computations we covered for a loop traverse:

  • The angular misclosure is dependent on available directions at both ends of the traverse - if either is not available, then misclosure can neither be determined nor compensated.
  • The relative or absolute position of the endpoints must be known - latitude and departure closure conditions are dependent on the end point relationships.
  • A link traverse does not have an area. Although the Area by Coordinates or DMDs equations can be applied and yield a numeric result, that result will not make sense as an area.

All other computations; lats and deps, traverse adjustment, adjusted lengths and directions, and coordinate determination; are performed in the same manners as for a loop traverse.
