GrafNet computes a traverse solution automatically after processing each session. The traverse report is written to a TRV file and opened automatically in GrafNet's internal viewer.

Traverse Solution

Prior to generating the network adjustment report, it is recommended that you view the traverse report. The traverse report contains useful information, particularly a report on any loop, check and duplicate ties in the project.

For stations that have more than two baselines connecting, a loop tie is computed. This means that there is more than one possible transfer of coordinates to this point. The first transfer is used for coordinate generation. Subsequent transfers are used to compute loop ties. The loop ties are good for locating erroneous baselines but they are an accumulated error of many baselines to that point. This means that the last baseline in that traverse leg may not be the erroneous one. These ties also give a good indication of the accuracy of the network, but the magnitude of the errors will be larger than the network adjustment residuals. The traverse method accumulates errors (closures) while the network adjustment spreads these errors across the whole network.
