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 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
Selecting grid file and additional properties
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.
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.

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 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.
Back to the Support Portal
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.

Also in this release, Advanced Catenary Support has been added, where it is possible in real time to use advanced catenary tools to compute the tow cables & anchor chains involved in a rig move using a rig and one or more anchor handling tugs. This release of QINSy allows for a template file to be loaded and after which certain parameters may be changed in real time (i.e. tow wire length, anchor chain length, anchor status, rig and tug locations). During each computation cycle the catenary of both the tow wire and the anchor chain and the location of the anchor are computed after which they are displayed in the 3D Grid display.
