Overview of QPS Qimera v2.7.1

Qimera v2.7.1 is a minor maintenance release in the Qimera 2.7 series from QPS (Quality Positioning Services), a leading hydrographic software for processing, editing, and visualizing multibeam sonar and LiDAR data. This version focuses on bug fixes, performance tweaks, and minor enhancements to improve workflow efficiency for surveyors, oceanographers, and marine engineers. It builds on the core strengths of Qimera, such as its dynamic surface generation, variable-resolution gridding, and seamless integration with QPS’s ecosystem (e.g., QINSy for acquisition and Fledermaus for 4D visualization). Released as part of the ongoing 2.7 updates in 2025, it addresses issues from prior patches while maintaining compatibility with large datasets from systems like Kongsberg EM-series.

Qimera excels in real-time data cleaning, uncertainty modeling, and product export, making it essential for bathymetric surveys, seafloor mapping, and environmental monitoring projects.

Key Features

  • Data Import and Processing: Supports a wide range of formats including .kmall (Kongsberg), .s7k (Teledyne), GSF, and PDS2000. New in 2.7 series: Improved latency handling during GSF imports to prevent double-application, and command-line support for .s7k imports.
  • Editing and Analysis Tools: Enhanced SVP (Sound Velocity Profile) editor for multi-selection adjustments; slice editor with partition support; and tools for excluding nuisance soundings during import (e.g., from FAU/LAS files) to reduce clutter.
  • Surface and Grid Management: Dynamic Surfaces with variable resolution; operations like contouring, grid differencing, and ARA (Automatic Relative Alignment) layers. Fixes for internal array offsets in EM-series systems when using non-full SVC workflows.
  • Geodetic and Project Handling: Updated UI for geodetic settings, project dialogs, and vertical transformations (e.g., no reprojection for SD models with QINSy geoids).
  • Integration: Direct export to Fledermaus SD, QPD (QPS Point Data) format, and other products like soundings or static grids.
