Transitioning research to operations: The case of wobble analysis

Jonathan Beaudoin, John E. Hughes Clarke, Maurice Doucet


Errors in mapping system configuration and integration can lead to dynamic data artefacts that vary with platform motion, resulting in so-called "wobbles" in bathymetric data. Recovering from these types of problems is sometimes possible in post-processing, however it is generally desirable to address these types of issues prior to acquisition. These typically require experienced or even expert personnel to diagnose, however, it is not feasible to have your best personnel on all mobilisations for all projects as this can lead to very high staffing costs. Even with experienced and expert personnel, there is a general lack of good troubleshooting software to streamline and facilitate diagnostic efforts.

Methodologies to diagnose these types of problems have been developed at the University of New Brunswick's Ocean Mapping Group (UNB/OMG) in 2003 and have since been used successfully in a research environment. Though there has been continued interest from the marine geomatics community to have such tools at their disposal, there has been no effort to port the research tools to commercially available software until recently. A few isolated efforts have been made to transition the research tools to a production environment with very limited success.

In this paper, we discuss the implementation of the UNB tools in QPS Qimera. In particular, we explore the process of transitioning a research grade tool that was designed by and for expert users to a tool that is usable by non-expert personnel. Real examples from problematic data sets are examined, to demonstrate how the tool is used.
