Qimera Export Menu

Qimera - Export Menu

The export menu allows you to export to various formats from raw files, processed point files, dynamic surfaces and static surfaces

Raw Sonar File

This sub-menu is active when Raw Sonar files are selected.

to ASCII

This will launch the Qimera Export Soundings to ASCII Dialog and will export the currently select raw sonar files. 

to Processed Points

This will launch the Qimera Export Processed Points Dialog and will export the currently selected raw sonar files.

to GSF

This will launch the Qimera Export to GSF Dialog. If the file has not been processed, you will be asked to process the file first. The files will appear in the Export folder within the Project directory. 

to FAU

This will launch the Qimera Export to FAU Dialog. The files will appear in the Export folder within the Project directory. 

To QTR

This option will export the currently selected sonar files to a QTR file for use with PREMO. You have the option to export all lines to a single file or individual files for each selected line. The files will appear in the project's Export folder.

To SD Points

This option will export the currently selected sonar files to SD Point objects.  Qimera will also pay attention to a spatial selection.  You have the option to specify which systems to export.  Qimera will add a UserAdditional system for each multibeam head that will be the container for any water column picks that you add.  You also have the option to merge all the lines into a single SD and an option to automatically load the SD object to the scene.  Qimera exports the following attributes to the SD Point object:  X, Y, Z, Time, System, Ping, Beam, Intensity, Horizontal TPU, Vertical TPU.


To SD Cluster

This option will export the currently selected sonar files to SD Cluster objects.  Qimera will also pay attention to a spatial selection.  You will see the same option dialog as you do when exporting SD Points.  You have the option to specify which systems to export.  You also have the option to merge all the lines into a single SD and an option to automatically load the SD object to the scene.

SD Cluster Export

If you have done water column picking of geophysical processes such as seeps, use this option to export only your water column picks (SystemName_UserAdditional) into a single SD Cluster object.  Then load this object into Fledermaus to do cluster analysis.  Remember you can do water column picking for all of your lines, then export all line picks into a single object using the Merge to single file option.

Track to ASCII

This will launch the Qimera Export Track To ASCII Dialog.


Processed Point File

This sub-menu is active when Processed Point files are selected.

to ASCII

This will launch the Qimera Export Soundings to ASCII Dialog and will export the currently select processed point files. 

to Processed Points

This will launch the Qimera Export Processed Points Dialog dialog and will export the currently selected processed point files.

to FAU

This will launch the Qimera Export to FAU Dialog. The files will appear in the Export folder within the Project directory. 

To QTR

This option will export the currently selected sonar files to a QTR file for use with PREMO. You have the option to export all lines to a single file or individual files for each selected line. The files will appear in the project's Export folder.

Dynamic Surface

This sub-menu is active when a Dynamic Surface is selected.

to Surface

This option launches the Qimera Export Surface Dialog dialog to export the currently selected dynamic surface to a number of different grid formats.

to Image

This will open a file browser to save a georeferenced image file, either TIFF or JPEG, of the surface colours.  Choose the image type by selecting the file type from the file type drop down.  Note that for JPEG, a TFW file with with the origin at the upper left, compatible with major GIS packages.  TIFF files will be written as GeoTIFFs with full georeferencing information.

to QINSy Sounding Grid File

This will open a file browser to select the name for the exported QINSy Sounding Grid file.

to QINSy Sounding Grid Layer

to Soundings

to Shoal Soundings

This will launch the Qimera Export Shoal Soundings Dialog dialog.

to Bag Surface

This will launch a file browser to select the name for the exported BAG and then the Bag Metadata dialog to enter the Bag metadata.

to CUBE Surface

This will launch the Output Surface dialog.

to BBH File

This will open a file browser to select the name for the exported BBH file.

BBH is an acronym for Basis Bestand Hoogte which is a format used by the Rijkswaterstaat (Dutch government) to store gridded data together with slope information in a database.

The export is only available for dynamic surfaces as it will require the sounding grid and the QPD footprints the grid is generated from.

For all footprints contributing to a grid cell a regression plane is calculated. From this plane the slope parameters are calculated needed for the export.
The calculation is only performed when 6 or more footprints are contributing to a grid cell.

Example:
