The soundings and grid that are computed online are the starting point in Qimera. For non- QINSy users, Qimera performs com- plete hydrographic processing for most modern sonar formats (.db, .all, .s7k, .hsx, .jsf, .gsf, .sff, etc.) and supports many ancillary formats (SBET, PosPac, most tides and SVP). Regardless of the acquisition package, final product de- livery is supported via a variety of ex- port formats (GSF, FAU, BAG, Arc and other image formats). Paradigm Shift The Qimera paradigm shift is the reduction of human-induced TPU. This is accomplished through automa- tion of mundane and error-prone tasks (transcription automation and process- ing state management) to isolate the stages for which the hydrographer is best suited. These stages include: data validation, processing configuration management and troubleshooting. To accomplish this, two types of workflow improvements are incorporated: guid- ed and dynamic. The guided workflow allows for nonexpert users to arrive at typical bathymetric deliverables with little training or expert knowledge. The dynamic workflow is processing state management that codifies and manag- es the relationships between the obser- vations and the results. You don't need to remember what processing needs to be done but rather that "some" pro- cessing must be done. Everybody, re- gardless of knowledge or experience, should be able to walk away with a product. Using What's Already There The guided workflow in Qimera is simply a series of prompts that step the user from one stage to the next. However, the innovation lies in the background. Upon opening Qimera, a minimum of seven functions are auto- mated. For example, creating a project establishes the file structure, organizes by file type (processed, grid, image, SVP, tide, SBET) and structures the stor- age of raw, processed data and export- ed data. Most modern file formats (.db, .all, .s7k, .gsf) contain all the necessary information required for processing as setup prior and during acquisition. Qimera utilizes all available informa- tion to guide the user, thus eliminating the necessity of manual checklists. File import searches each format for what information exists (range, angle, mo- tion, dynamic heave, SV, SVP, etc.), catalogs it, transcribes all vessel con- figuration information, processing configuration, and then performs the initial processing such as ray tracing based on the all-raw data (bathy and ancillary), etc. Following the initial au- tomated processing, Qimera prompts you as to how you wish to create your surface. Resolution, CUBE settings and color map are presented in a simplified interface. Within five clicks and less than 60 seconds, the user has a map and is now ready to utilize one or more of Qimera's data-editing tools to clean and validate data, apply SBETs or edit and validate both the assembled bathy- metric data and the ancillary data used to calculate them. 'Off The Boat' Deliverables: Qimera Live The steps outlined above are often referred to as "pre-processing," when initial mathematical operations are conducted, leaving only data valida- tion and cleaning. Real-time data pre- processing currently exists within QIN- Sy but only for people logging within its native format. For operators logging in non-native formats (.all, .s7k, .gsf, .jsf, etc.), QPS has introduced this au- tomated and stand-alone processing functionality into what is referred to as For cooperative multiuser cleaning, Qimera breaks up the project based on user-defined parameters. This example shows a simple grid of nine subprojects. USA 1.508.291.0057 Clearly Superior Imaging SONAR SYSTEMS SUB-BOTTOM PROFILERS BATHYMETRY SYSTEMS SIDE SCAN SONARS
