26 st / September 2017 Chris Malzone is the general manager for Quality Positioning Services Inc. (QPS). He has an M.S. in oceanography/geology and has worked in hydrogra- phy and related ocean sciences since 1992 in a vari- ety of roles ranging from scientist to hydrographer to general manager. multiple users contributing to an overall processing effort through cooperative cleaning and production-line process- ing. Cooperative cleaning allows multiple users to clean a large project by dividing it into smaller, more manageable projects while maintaining data integrity. Data processors work within their subprojects and, once complete, intro- duce their efforts back into the main project. In parallel, the main project may have ancillary data processing completed (e.g., SBET, SVP, height corrections). The edits from the sub- projects may be incorporated back into the main project without affecting the overall progress of the entire project but enormously increasing efficiency. Product-line processing allows for projects to be broken down into stages. These stages can be done based on survey days, survey segments, survey vessels, etc. The processing for a stage (e.g., a day, vessel, segment) of data is handled in its own processing project. The processed outputs from this effort can be aggregated into a master project that is evaluated by the senior hydrographer review. During re- view, the stage project may be accepted and immediately incorporated into the master project or sent back for ad- ditional processing. This is done repeatedly and combined with other stages within the master project. The net result is the integration of multiple smaller projects processed in the exact same manner into a final deliverable. Summary QPS has evolved the hydrographic workflow to provide a dynamic, multidimensional user interface that allows those even with a low knowledge threshold to make good deci- sions that lead to high-end final products. Users may either utilize QINSy to provide real-time computations to reduce post-processing to simple cleaning and validation or pair existing acquisition solutions with the guided workflow in Qimera. Regardless of approach, the critical component is the isolation of tasks within the workflow to capitalize on advances in computing technology to automate the mun- dane, error-prone tasks to bring more value to the stages in which humans bring value. QPS, through QINSy and Qimera, innovates the user experience through several key design features including: guided workflow, transcription automation, processing state management, real-time QA, dynamic workflow for valida- tion, autonomous processing, collaborative cleaning and production-line processing. This reduces human error and the QA burden in general and lowers the knowledge bar- rier to entry. For the hydrographic manager, the return on investment is found in lower training costs due to the guided workflow (easier to learn and retain knowledge), improved processing outcomes, scalability, reduced post-processing times and more accurate results. References For a list of references, contact Chris Malzone at mal ST Qimera Live. With a single command within Qimera, the "Live" functionality automates the guided workflow such that by the completion of every survey line, preflagged data files create and/or update a fully georeferenced gridded sur- face. The surveyor may choose to use Qimera Live to imme- diately identify problems in post-processing or have a com- pletely autonomous processing solution that can deliver a final product upon hitting the quayside. Qimera Live is a part of the standard Qimera installation and is maintained through the standard release cycle. It may run on a separate computer or on the acquisition machine, allowing maxi- mum flexibility for implementation in autonomous opera- tions, remote vessel operations and/or multivessel surveys. Immediate Feedback: Data Validation In Qimera, data validation consists of creating a loop be- tween the observed surface and calculated results to expose errors immediately. This is referred to as "Live" processing state management. In Qimera, it is very easy to make pro- cessing configuration adjustments or to perform data vali- dation and to immediately assess the impacts of changes. Near-immediate feedback shortens the time between cause and effect while promoting causal reasoning, which is a key ingredient for natural cognitive evolution. In short, it allows users to train themselves through something as simple as immediately recalculating the dynamic surface and show- ing the user he/she has accidentally deleted good data or applied the wrong SVP, etc. Scalability: Collaboration, Production-Line Processing QPS provides workflows within Qimera that scale to P.O.
