New Export Formats

Quick setup for VisualSoft Export

In the Generic layout editor the option is added to quickly generate a new layout in order to export raw profiler data to VisualSoft's file format. Select from the File pull-down menu option Generate Layout, Export, Visual Works...A dialog will appear where the user only has to select which profiler (or multibeam) system to use. Finally, pressing the generate button will automatically create two layouts, one called XP and one called RAWSURVEY.

These two layouts can be used in the Export Generic Wizard in order to export your raw profiler data to files which can be imported into VisualSoft's VisualEdit Professional Processing software.

 

 

LAZ/LAS Data Format Export

In this version of QINSy it is possible with the Processing Manager to export QPD data to the LAS/LAZ format. The LAS format is a public binary format typically used to exchange 3D point cloud data. The format originated in the LIDAR community, and LAZ is a compressed version of the LAS format. The export module supports version 1.2, 1.3 & 1.4.

 

WCD in SBES Display & WCD Editor

In this version, Water Column Data (raw echogram) support for Single Beam Echo Sounders (WCD SBES) was added to both the online Single Beam Echo Sounder display and the offline Water Column Data Editor. This makes it possible to add the WCD as a background in the Single Beam Echo Sounder display and to monitor the quality of the bottom detection while recording the data. It also makes it possible to monitor any other reflectors present in the water column such as gas seeps, wire or seaweed. See example:

 

Offline, using the WCD Editor utility (Processing Manager) allows the user to quickly check and even to alter digitized depth (with the changes being written directly to the QPD file), see example:

 

 


3D Editor in Processing Manager

 

3D Editor added to Edit ribbon of the Processing Manager

 

With a valid QLOUD license, now a 3D editor is available in the Processing Manager. First an area needs to be selected and then the editor can be started. The editor has keyboard shortcuts available so that editing can be done by using mouse and keyboard in combination. For further information there is a Howto document available in the Knowledge base and also the online help has a description of the new functionality.

Fledermaus 7.4.1 (released 4 July 2014) included new tools for working with watercolumn data – semi-automated feature detection and cluster analysis.  These research tools were originally written by Dr. Tom Weber of the Center for Coastal and Ocean Mapping (CCOM) at the University of New Hampshire to help detect seafloor seeps in watercolumn data.  The QPS developers have used the Fledermaus plugin architecture to create a new tool that is now available to all FMMidwater users, another example of successful partnership between researchers and industry. 

We will be hosting webinars on July 22nd and July 23rd to demonstrate the new functionality, please visit the webinar event page for more information and to register.  We have also created two new Howtos with step-by-step instructions, the first explaining how to use the Feature Detection tool in FMMidwater and the second describing the associated Point Clusters SD object and clustering analysis tools found in Fledermaus.

Line Data Manager Functionality

The majority of the Line Data Manager functionality has been integrated into the Processing Manager. Future QINSy versions will likely include the as yet not ported functions. For the time being the Line Data Manager may be used to perform these functions. In preparation for new functionality the Processing Manager stores the survey line data in two file formats. The first file format is the PRO-file format which is also used in the Line Data Manager and the second format is the QGF-file format. In future releases the QGF-file format will be used throughout QINSy.


Line Data Manager showing PRO-file

The Line Data Manager functionality may be found in a separate ribbon which becomes available after selecting a Line file in the Project Explorer pane. A Line file may either be newly created by selecting the New Line from the File menu or by importing from a AutoCAD DXF, DWG or Microstation DGN file. An option is also included to export the data to AutoCAD DXF file format where by the following AutoCAD versions are supported: R13, R14, 2000, 2004, 2007, & 2010.


Improved workflow to generate grid from QPDs

Only two steps need to be executed in order to fill a grid using a number of QPDs:

1.Select QPDs which are to be added to the grid file
2.Select/Create the grid file and additional properties.


Selecting QPDs to add to grid file

Improved workflow to edit data using Qloud

It is no longer necessary to separately group the QPDs. The user may just select the QPD files and choose the edit in Qloud option.


Selecting QPDs to be edited in Qloud

 

Once the correct files have been selected the QTM file settings may entered. This dialog gives the user control over which systems will be part of the QTM file and what information will be transferred into the quality field of the QTM file. In case a Navigation Surface was created the program will re-use as many settings as possible.


QTM settings dialog

 

Once the QTM file creation is finished Qloud will open to allow processing. While processing in Qloud the QPD files will remain marked as locked in the Processing Manager.


QPDs being edited in Qloud shown as locked

 

When the processing is finished and Qloud is closed the user is given the option to immediately synchronize the changes made to the QTM file back to the QPD files.

Synchronize changes in QPD dialog 

 

The user may however decide not to synchronize the changes in the QTM file to the QPD files. This will allow the user to come back at a later stage and resume editing in Qloud i.e., the next day.

While the changes in the QTM file have not been synchronized back to the QPD files the QPD files remain marked as modified.


QPDs shown as being modified 

 

Once the user is finished processing the data in Qloud the changes may be synchronized back to the QPD files by using the Synchronize option.


 

 

When: Version 7.4.1 of the Fledermaus Suite, released 4 July 2014 includes an important bug fix that may impact the appearance of your processed backscatter.  

What are the changes?

It was recently discovered that the backscatter corrections being done in FM Geocoder Toolbox (FMGT) were not correcting for seafloor 3D incidence angle, even when corrected bathymetry was included in the processing routine.  We have added a fix to use a Reference Grid (in Fledermaus SD format) to determine the topographic slope during processing and mosaic creation.  To clear up any potential confusion, it is important to point out that the corrected bathymetry data that has been necessary to import data into FMGT have only ever been used for georeferencing seafloor imagery.  The original Geocoder software from UNH provided the ability to compute the 3D incidence angle with a Reference Grid, however, this was only implemented for sidescan sonar imagery and not for multibeam imagery.  We have followed the same strategy for multibeam imagery now and the Reference Grid is now used to estimate each beam's 3D incidence angle with the seafloor.  This more accurate method of calculating the incidence angle directly improves the accuracy of the ensonified area correction, which is a function of the projected beam footprint size on the seafloor.

While implementing the Reference Grid calculations for multibeam imagery, a small number of errors were noted in the original UNH Geocoder approach.  These were corrected for the multibeam imagery correction algorithms, however, the corrections have not been ported to the sidescan signal level corrections yet.

Who does this impact?

This type of correction is particularly important for ARA users since the input signal to ARA now represents the seafloor's true backscatter value with much higher fidelity than before.  For FMGT users who focus primarily on creating seafloor mosaics only, the new algorithm will dampen topographic effects, such as higher signal levels on inward facing slopes and lower signal levels on outward facing slopes.  As part of our ongoing efforts to improve the underlying Geocoder algorithms from UNH, we have identified the need to propagate the angle and terrain corrections into the AVG stage of processing.  Once this is complete, mosaic imagery will have a much higher fidelity in representing seafloor backscatter.  Look forward to this in a future release.

The terrain correction can be applied for Kongsberg, Reson and R2Sonic multibeam systems that have the sonar beamwidth and pulse length parameters correctly recorded in their data stream.  The corrections are done for both .ALL input format (Kongsberg only) and for .GSF (Reson, R2Sonic and Kongsberg).

Where to get more help?

This HowTo explains how to add a Reference Grid and create a new mosaic.  If you have any questions or need further clarification, please contact Support (support@qps.nl).


 

The American Polyconic projection may be visualized as "rolling" a cone tangent to the Earth at all parallels of latitude, instead of a single cone as in a normal conic projection. Each parallel is a circular arc of true scale. The scale is also true on the central meridian of the projection. The American Polyconic projection is used in Brazil and the South Pacific.

 

QPS recently added the option within the QINSy Processing Manager to group your data based on multiple levels of associated metadata. This is a very powerful option giving you the ability to present or organize your survey data files in numerous ways. Simply by dragging one or more column headings, the user may group the data files based on any metadata field. Examples of these fields are vessel name, start date/time, etc…

The Project Explorer window below shows the Project Tree on the left and the Detail View on the right:

 

Detail View after dragging the ‘Vessel Name’ column heading to be used to filter survey files:

 

 

Once the user is content with the chosen grouping settings, they may be stored and then accessed by the Preset drop down list. Grouped data can be highlighted in the Plan View by simply selecting the group in the Detail View. The tracks of the selected data will be drawn in the Plan View using a thicker line.

Drivers

The following drivers we implemented or extended:

 

Reson Seabat T20-P Driver

The existing driver was extended with support for non-MBES system types such as Gyro compasses, Pitch roll & heave sensors and Position Navigation systems.

 

Leica P20 laser scanner Driver

A new driver was added to support the Leica P20 laser scanner. This driver may be used to decode the laser data and control the laser scanner.

 

 

 

While generating the navigation surface in the Processing Manager, it is possible to also produce a CUBE surface which may be inspected and modified using the Fledermaus 3D Editor. During the creation of the navigation surface, the CUBE surface generation may be enabled using the checkbox and the CUBE settings may be entered by clicking on the button next to the checkbox.

Make a new Navigation Surface:

 

 

CUBE Settings:

 

CUBE settings may be saved in a configuration file so that they can be reused in future projects. After generating the navigation surface, the following CUBE properties may be visualized in the Processing Manager:

  • CUBE Depth
  • CUBE Uncertainty
  • CUBE Hypotheses Count
  • CUBE Strength
  • CUBE Number of Soundings

The 7.4.0 release brings with it a number of installation changes that long time Fledermaus users may want to be aware of.  First to be more consistent with other QPS products and company branding the software is stored under a QPS directory. On Windows this will be “C:\Program Files (x86)\QPS\Fledermaus” for the 32 bit version and “C:\Program Files\QPS\Fledermaus” for the 64 bit version.  On Windows the location of the preference files have moved as well. They are are now found in C:\Users\%username%\AppData\Local\QPS\Fledermaus, or "%localappdata%". Previously preferences were located in C:\Users\%username%\AppData\Roaming\IVS.

On Windows when you run Fledermaus to install a license file if you run it with administrator privilege the license will be installed in the licenses directory where the software is installed. However, if you install the license file as a normal user the license will be installed in the C:\Users\%username%\AppData\Local\QPS\Fledermaus\licenses directory. If you are installing a license for multiple different users on a windows machine make sure you install the license with administrator privilege or copy the license directly into the licenses directory where the software is installed.

Previous versions used an environment variable called IVSHOME7 to tell the system where the software was installed. As of version 7.4.0 this environment variable is no longer used and all configuration files are located based on a relative path from where the executable(s) are located. This makes it possible to better support the installation multiple versions of Fledermaus (or both a 32 and 64bit version) without any potential conflicts.

Please see our Installing Fledermaus on Windows guide, and Fledermaus 7.4.0 License File Locations knowledge base article for further information.

Everyone at QPS is pleased to announce that Fledermaus 7.4.0 is now available for download. Many new features and improvements have been made with this release:

  • The core rendering engine has been greatly improved and will take better advantage of modern graphic card capabilities. The greatest improvement with this release is for surface objects, which will now be much less degraded during interactive mode. The software now has a requirement that your graphics card support OpenGL 2.1 or newer.
  • QINSy projects can now be directly opened in Fledermaus and used with the Fledermaus area based editing tools. All edits are immediately applied to the QPS files in Fledermaus, so no unload is required.
  • The Mac OS/X distribution is now 64-bit and replaces the previous 32-bit version.
  • All Fledermaus applications now share a common installation location with QINSy. Common files, such as datum grid shift files are shared across applications.
  • You can now easily install separate 32-bit and 64-bit installations of Fledermaus (Windows only).
  • The Windows installation can now be installed locally for one user, or globally for all users of a machine.
  • The licensing management and user interface has been greatly improved and has better functionality for multi-user installations.
  • The Fledermaus applications now use a common geo-referencing engine with QINSy, which means all coordinate systems defined in QINSy are also supported in the Fledermaus tools.

Please check the Fledermaus Release Notes 7.3.4.a - 7.4.5.b for further technical details.
