Geocap 6.3 Release Notes

About this release

We are proud to present Geocap 6.3 which contains considerable technological advances in the areas of seismic data loading and seafloor data management. See our illustrated highlights section.

Together with improvements in everything from workflow recordings to arbitrary image georeferencing Geocap asserts itself as a true multipurpose tool for the geoscientific community.

We discovered a potentially serious bug in our Oracle connection in Geocap 6.3.0. This release has been replaced by Geocap 6.3.1, which is available from our download page.

1) Do not connect Geocap 6.3.0 to any Oracle database.
2) Uninstall Geocap 6.3.0
3) Download and install Geocap 6.3.1

Please note that the use of Geocap 6.3.0 is OK for any other purpose than connection to Oracle databases.

Some highlights in Geocap 6.3

1. New seismic brick cube technology

Brick technology allows you to display and process arbitrarily large 3D seismic datasets using parallel processing and brick partitioning.
This technology was developed for handling huge datasets on relatively small computers. We have successfully imported a 314 Gigabyte SEG-Y file and run the visualization on a laptop computer.

2. Multibeam editing and flagging in 2D and 3D

Multiple multibeam survey lines can now be edited in both 3D view and 2D cross section view simultaneously. The same editing capabilities are available both in 2D and 3D.
The editor has undo/redo functionality. Deleted points are only flagged (marked) as deleted, and can easily be un-deleted at a later stage.

The new Point Flag Visibility Filter dialog lets you easily control the visibility of any set of XYZ points according to their flags. When adding filters the default mode is Hide.

Editing in both 2D and 3D

3. Georeferencing - Morph and World pick

The Geo Reference command will now show the image/map in a standalone window. This enables you to pick reference tie point from displayed data in the graphics window using the World Pick button.

A new georeferencing method has been added. Morph image can be used to force an image/map to fit, using an arbitrary number of tie points. The new image will have a 100% match in the position of the tie points.
In the area between tie points, the image will be interpolated smoothly. Using this option, the new image is a re-sampled version of the original image.

A new Preview button lets you evaluate the result by displaying it in the graphics window together with other data, before completing the georeferencing.

4. Workflow Recorder and easier data input

The workflow recorder makes it easier than ever to create and modify workflows. Start recording, and commands will automatically be added as elements to the workflow as you make your visualizations from the project.
Several other improvements have also been added. By copying commands from the Toolbox and into the workflow, the selected dataset in the project will automatically be used as input data.
To change input data, simply select the dataset in the project and click the icon.

Workflow example

5. Default commands

Project datasets now have a default command that are directly accessible in the dataset's Properties dialog. A default command is executed when the dataset is checked in the project view.
Choose an item commands or a schema commands and click on the to mark the command as the default command.

Setting the default command in the properties dialog

6. Adjust Seismic

The new command Adjust seismic using a correction line contains functionality for adjusting seismic by grid surfaces, interpretations, digitized lines or correction tables e.g. tidal corrections.

The upper section is the initial (Before) situation showing a green interpretation line on the seabed and a red line where the section intersects with the multibeam grid surface. The lower section (After) shows the adjusted seismic, now shifted to the red line. The abandoned green line is displayed just to visualize the distance the signal has been shifted.

Other seismic manipulating commands for depth conversion and creating seismic sub-sections has been present for a while.

7. Seismic visualization

Ever wondered what is hiding behind the watercolumn part of your seismic section? In Geocap 6.3 the command Seismic Subsection removes/makes transparent the seismic above a line, an interpretation or a grid surface. In addition Seismic Subsection is used for creating sub sections limited by shot point range, Z-value (or inline/crossline range for 3D seismic).

Default situation - the watercolumn is displaying in front of whatever is behind.

Use the command Seismic Subsection to chop of not needed portions above/below/outside a line/an interpretation or a grid surface.

8. Display interpretation from a Seismic Line

In earlier Geocap versions you had to manually locate the interpretation from the project or through the main Interpretation panel. In 6.3 a new command Display IHorizons has been added to the Seismic Line schema.
This command lets you browse in your interpretation folder and then select which horizons to display for that specific seismic line. For efficient use on ongoing interpretation projects,
this may be switched to direct mode and set as an item command after the initial settings are set.

Interpretation display

Interpretation: You may now use Space or p from the keyboard to do new pics in your interpretation. Using Space may reduce the risk of strain injuries.

9. Calculate vertical, horizontal and total distance

Previously it was only possible to meassure the total distance in 2D and 3D. Now it is also possible to measure vertical and horizontal distances in 3D. When in 3D mode, press Y on the keyboard to set start and endpoints.
All the distances will be listed at the bottom of the panel. A white line will show the measured distance.

Distance calculation in 3D


  • Edit > Recent projects will now preserve the data listing and sorting in File > Recent projects.
  • Several improvements has been made to the LOD Grid Display and LOD Points Display commands.
  • Scripted commands may now be set not to copy project data to workspace during execution. This option is available as a check box on the edit menu. Using this option will improve the execution time significantly for some commands.

  • Distance calculation can now calculate vertical, horizontal and total distance in 3D by pressing Y on the keyboard. It will also show a line between measured points. See highlights above


  • A new concept: Default command has been introduced (see illustrated highlights above). The user can now decide witch command should be executed when clicking the check box next to a dataset in the project. This functionality is available on the Properties menu on a dataset, under a tab called Default Command. Specify a command type first, either Item Command or Schema Command, then select which command to use by clicking the icon.
  • Keyboard key x, to set the focal point, now works for all kind of points display. Previously you had to point at an object displaying a surface.

  • Item commands are now preserved for simple features layers.
  • Geocap will now remove GIS data source properly.
  • The Display Simple Features command can now be opened in workflows.


  • Fix: Seismic Subset from a Seismic Data folder will name resulting subsets after the individual seismic datasets, not folder name.
  • New command: Adjust seismic using a correction line adjusts the Z-values of the samples (e.g. to align seabed reflector in seismic with actual seabed), see illustrated highlights above.
  • Improved commands for Seismic Lines
    • Seismic Annotate: improved annotation offset and coincident topology
    • Seismic Display: improved handling of undefined values (transparency)
    • Seismic Subset: creation of subset above/below/between limit line(s)

    • Anisotropic diffusion
    • Bandpass
    • Trace mix.
  • Undefined values are transparent and has a vague outline in Seismic Brick display
