Automatic Patch Test and Side-Scan Mosaic Tools in NaviModel 3.3 - 29/11/2013


Version 3.3 of the EIVA NaviModel software solution has been released, offering both improved as well as new features, including an automatic patch test module and side-scan mosaic tools. NaviModel version 3.3 allows for 3D, and thus more precise, patch testing, as opposed to previous versions that were based on profile scans. Also, users can create a custom display of the patch testing data, including graph selection.

Side-scan mosaic has been a well-known component in other EIVA NaviSuite products for a while, and it is now also included in NaviModel. The mosaic tool encompasses multi-beam snippets, backscatter data and side-scan data, allowing for intensity mosaic with automatic TVG.

The NaviModel update also includes an improvement to the patch test tool module, offering the possibility of a fast and automatic patch test with immediate visual feedback when fine-tuning the calibration, simply by dragging sliders to analyse the effect.
