Traverse Types

The following diagrams demonstrate the various types and combinations of traverses that may be processed using the Bowditch or None adjustment options, either as individual jobs or files, or as a collection of traverses within a single data set. (Note : these details do not apply to the LS-Network adjustment option which uses an entirely different procedure - refer to Network Adjustment - Least Squares for more information).

Figure 1: Radiations only

Figure 2: Open traverse with sideshots

Figure 3: Traverse with distance-only closure

Figure 4: Traverse (with sideshots) with distance and angle closure

Figure 5: Self-closing traverse loop closing back onto fixed starting point (with sideshots)

Figure 6: Traverse loop closing back onto a previous (closed or un-closed) traverse

Figure 7: Self-closing loop on end of open traverse (external angle closure)

Figure 8: Self-closing loop on end of open traverse (internal angle closure)

Figure 9: Secondary traverse (may be closed or unclosed) branching from a previous traverse (open or closed)
