RELEASE 1.0.0 - June 2015

Introduction

Qimera™ is a totally new multibeam processing application for production MBES processing. It is also the beginning of the transition of the various QPS applications and modules into new products and modules to provide an efficient mapping workflow.

The Qimera software:

  • strives for a paradigm shift in processing by automating those steps in the workflow that have been mundane or error prone, and minimizes and focuses the user interaction to stages when they provide valuable input,
  • has been built from the ground up and provides an intuitive and easy to use interface that also minimizes training required,
  • supports the QINSy data logging format in addition to sonar file formats from other hardware and software manufacturers,
  • extracts as much information as possible from incoming data files, including all ancillary data and survey vessel information,
  • intelligently and interactively guides the operator through the typical data processing stages with a Dynamic Workflow™,
  • offers the advanced tools such as the Wobble Diagnosis Toolkit for troubleshooting, in addition to the typical complement of multibeam data review and editing tools such as a Time-Series Editor, Sound Velocity Profile Editor, a Patch Test Calibration Tool, Swath Editor and 3D Area based Editor, and
  • uses a unique I/O Balanced Multi-Core engine specifically designed to process sonar data as rapidly as possible. Processing is done as a background task and the user can continue to interact with the project.

Operating Systems

The initial release of Qimera is for Windows Platforms only. Future versions will extend the platform to Mac and Linux. The following operating systems are officially supported under Windows:

  • Windows 7 (64bit)
  • Windows 8.1 (64bit)

Windows computers also require a modern 3D graphics card with good OpenGL support.

Bug Fixes

This is the initial release of Qimera and there are no bugs ;-)

There was an extensive external beta and pre-release program, and we thank all those testers that provided great feedback. Their feedback and contributions have no doubt helped to bring the product to the current level for the initial release.

Knowledge Base and Reference Manual

Qimera is packaged with the complete offline Knowledge Base, however these documents are under continual revisions and you should always check the QPS webpage  for the most up to date version . Information provided includes:

  • Getting started – installation, licensing, and Quickstart guides,
  • Howto Articles – covering major workflow processes, and 
  • Reference Manual.

Technical Support

If you need technical support or to log feedback or a bug, please go to: https://jira.qps.nl/

When providing feedback or reporting a bug please create an issue in Jira. Please select the Qimera Support (SQM) project from the selections in the Project drop down menu.

Other Online resources

  • Geoid and separation models.  If you are surveying to the ellipsoid and require separation models for transformation you should check that the one you require has been included in the installation package. Not all worldwide geoid and separation models have been included to keep the installation download to a manageable size. Other models are available for download on the Qimera download page.
