Qimera 1.5.4 Release

Introduction

26 July 2017, We're pleased to present Qimera 1.5.4

Users who do bathymetric processing in Qimera and backscatter processing in FMGT should upgrade both applications to their latest versions.

When exporting GSF files from raw sonar files, Qimera will now follow the GSF convention and will report soundings relative to the vessel reference point and will also report the position of the reference point. Previously, the soundings were reported relative to the sonar head and the ship position was reported at the sonar head as well. Even though this previous method provided mathematically correct results, it made for difficulties during import of the GSFs into other applications as well as back into Qimera. The new method addresses these shortcomings. To be clear, GSF results from previous versions of Qimera are correct but they require manual configuration of vessel configuration files in Qimera and in other applications when re-processing the data. These changes to the GSF export from Qimera also required some improvements to FMGT.
