Qimera Export Menu

Qimera - Export Menu

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

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 selected raw sonar files.

to Processed Points

This will launch the Qimera Export Processed Points Dialog and will export the 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 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 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 User Additional 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, and Vertical TPU.

To SD Cluster

This option will export the 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 selected processed point files.

to Processed Points

This will launch the Qimera Export Processed Points Dialog and will export the 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 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 Grid

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

to ASCII/Grid

This option launches the Qimera Export Grid Dialog to export the selected dynamic Grid to a number of different grid formats.

to Image

This option launches the Qimera Export Grid as Image Dialog, followed by a file browser dialog to select the filename of the exported image.

to 3D PDF

This will open a file browser dialog to save the currently selected Grid as a 3D PDF.

to KML

This option launches the Qimera Export Grid to KML Dialog to export the currently selected Grid to KML and KMZ formats.

to Static Grid File

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

to CUBE

This will launch the Output Grid 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 grids 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 and needed for the export.
The calculation is only performed when 6 or more footprints are contributing to a grid cell.

Example:
