Data cleaning in Qimera

Data can be cleaned in the following ways with Qimera;

  • Individual sensors data can be edited and the effect will be applied to the files affected by the change
  • Manual data cleaning can be conducted in the Swath Editor (2D, line/file by file), the Slice Editor (2D, selected area) and in the 3D Editor (selected area)
  • The Spline Filter from Qloud is in Qimera with all the default settings as before and it is now possible to choose Custom values
  • The PFM filter to edit soundings based on their distance from the CUBE surface is in Qimera
  • Realtime filters are carried into Qimera and are applied.
  • The same filters can be used in Qimera to edit by depth, beam number, range, sector…

 

3D Editor:

Well known from Fledermaus, the 3D Editor has options for manually cleaning data, and also probably the most friendly implementation of CUBE.

 

Slice Editor:

QPS was pleased to release Qimera 1.3, the third full feature release since its initial launch just over one year ago.  With this release, we're continuing to expand upon the vision that we've set out for ourselves: to make hydrographic data processing intuitive and as simple as possible, all the while offering powerful capabilities to those that need them without cluttering the workflow for those that don't. As reported with the last release, we have followed through on our commitment to port the point editing workflow from Qloud into Qimera. The 1.3 release offers all of the built-in and customized filters that our Qloud users have relied on previously for an easy and responsive workflow. QINSy and Qloud users will find that the acquisition (QINSy) and processing (Qimera) workflow is much more streamlined BECAUSE QIMERA WORKS DIRECTLY ON THE QPD FILES. Qimera is definitely not just "a new Qloud".

The Slice Editor allows; a number of way to select an area of data for editing, a number of ways of colour coding, a number of ways of navigating, and number of ways of auto-updating / saving, a number of ways of filtering. In short, pretty much all the tools your likely to need when it comes to manual or automatic data cleaning!

Swath Editor:

The Swath editor tool in Qimera allows the user to edit one file/line at a time. Uniquely to Qimera, the beam values shown have been sound velocity refracted and vertically adjusted. Rejected data can be shown or hidden depending on what function the user wants to perform.

One great feature that the Swath Editor can be used for is to see what effect the filter selection will have on the data and how many outer beams can be rejected without causing gaps in the data. This is achieved because Qimera, by correctly calculating the beam value, can display the portion of the survey line shown in the Swath Editor in the 4D view in their true location. This makes it easy to see the effect of the filters and also to help the user edit where there are features on the seafloor.
