About this release This is a major upgrade release. The Geocap Seafloor interface and functionality is very much improved in this release. Much effort has been put into improving precision both in graphics and calculation, and Geocap ability to handle centimeter resolution is now expanded and improved. Numerous bugs are fixed and new functionality is added to all our products. We strongly recommend switching to Geocap 6.1. Note that there are no project model updates between Geocap 5, Geocap 6.0 and Geocap 6.1. The development on Geocap 6.0 was terminated in 2011. The Geocap 6.1 will continue to evolve, and incremental releases will be made in the 6.1.x series in the coming months. Themes:

Highlights

• Seismic 2D viewer has been added. The viewer is opened with the pulldown Windows > New > Cross Section Window. In addition to Seismic lines and Vertical calibrated images, other dataset e.g. crossing lines may be browsed into the viewer. Cross sections through overlapping point clouds is another application of this viewer. One obvious usage is to produce figures of seismic and interpretation that is not easily done in our 3D view. Future development may be seismic interpretation, editing of datasets and more. If you have any ideas, please let us know.

• LOD (Level Of Detail) Point Display. This enable Geocap to display very huge point datasets, e.g. multibeam data, lidar data and more with a dynamic approach. This will be further developed. Please give us feedback and input on what your needs might be.

• Major updates to Geocap Seafloor, see below.

• High precision (double precision) calculation and visualization implemented to address the need of centimeter precision in XY and Z in all coordinate systems.

• Improvements in memory handling.

Updates

Changelog

• 6.1.1

GUI

• Graphics windows fullscreen mode (for stand alone windows) is toggled using the Escape key, not Spacebar.

• Any number of standalone graphics windows may be now created. Standalone graphics windows are always on top.

• All graphics windows are represented with a small icon in the lower part of Geocap. You can click these to change active graphics window.

• Graphics toolbar: Three more camera directions (-x, -y, -z) has been added. Camera directions has been collected under one button. The camera now has a "fly-to" movement, instead of the old "jump-to" action.

• Operation Modes has been removed

• The menu entry Plugins has been removed. Everything related to plugin managment has been moved to Tools > Options > Plugins

• When focus is on the graphic window: Ctrl+C will copy the visual content to clipboard. This is convenient for pasting this as an image e.g. into a Powerpoint or whatever.

• A new icon for selecting (finding) displayed project items by dragging a rubber band rectangle in the graphics window. Returns a popup with a list of found datasets. The icon is found in the top icon bar, next to the Locate Project Object From Graphics icon.

The Project

• Copy and paste in the project now supports very large size data files. In previous Geocap versions there were problems with copy/paste on files that were of Gigabyte sizes.

• The project save button has an entry 'Free memory cache' that frees memory used by the project. Click the tiny arrow behind the diskette icon. This is irrespective of cache size. Only objects that are unmodified will be released. The Project memory size is listed in the message window.

• Scripts and text objects in the project are now supported in a Generic folder. The Scripts folder is deprecated.

• Table View: Clear selection button available on dataset table view.

Commands

• ConvertToSeismic for VCIs (vertical calibrated images) now handles conversion by color table. This means that the colors in the color table will be used to set amplitude values in the converted seismic.

• Function can now set origo and spacing of structured points / image data.

• Calculate Line Distance can now set distance unit. Available units are meter, kilometer, nautical miles.

• Import ASCII Column reader reports line number of ignored lines. Lines are ignored when thy do not match import settings, possible because of errors in the files.

Scripting

• Command Log output can be redirected to the message window in the command log settings dialog. This may be used for debugging of scripts and scripted commands. To activate, open the command log under Windows > Command Log, click the gear wheel and Editor: Message window. OK - Maybe only for those of you that are scripting.

• qexistingdir returns forward slash '/' separators.

• Added command qfromnativeseparators to convert paths to forward slash /

• The sfdatasource command now has an argument 'warning on| off' to enable or disable warnings during the loading of spatial vector files

• Install Script has been moved to the Tools menu.

• An example script showing how to create a standalone QTcl window was added to the Help > Examples pulldown.

General

• Updated documentation. See http://www.geocap.no/doc

• Flight tour will now have a smooth transition between first and last camera in loop mode, if first and last camera are equal.

• Improvement: Deleted objects are moved to invisible trash and synced with disk only during saving of the project. This ensures that the project structure and corresponding datafiles are always consistent, avoiding datasets in the project manager pointing to non-existing data files.

• The area calculator now lets you drape the calculated area on a sticky surface with a user selected color and opacity.

GIM

• Command Assign inline/crossline coordinates added.

• Dedicated dialogs for surface creation from diagonal tracking.

• Surface attributes AverageTime and AverageAmplitude added.

Shelf

• Bathymetric profile analysis: The FOS (foot of slope) list can now display decimal degrees. Right click FOS list to change format.

• Bathymetric profile analysis: Distance calculation method combo text set to standard vincenty or flat earth + color on average gradient interval will reflected in interval text.

• Bathymetric profile analysis: Graphs are now not drawn on top of rulers. The rulers will have white background. + It is possible zoom further out than the with of the profile.

• Zoom to data now available on velocity profile.

• 1% Sediment Thickness Points: Columns for FOS name, analysis name, and profile name will be added to Table View, if they exist as columns in FOS dataset.

• Command Gradient Band Analysis now allow steepness up to 90 degrees.

Seafloor

Improved import of Multibeam Sonar data:

Shelf

• Command Optimize Outer Limit now creates or updates any "Point Distance" field data columns. At least if they are created in the latest Geocap versions. If you end up with a remnant of an old Distance to previous point (M) column, because your outer limit was created in an older Geocap version, then please just edit the dataset in Table view and remove that column.

• Copying amplitudes from seismic cube to workspace results in Structured Points instead of Image Data.

Known issues

• PDF3D:

  # Limited text character support. I.e. no unicode support. # Point size is unsupported and points are always black. # Line thickness is unsupported. # Rendering of transparent geometry is wrong from certain view directions # Geometry and or camera 'far' away from the origin generates problems for Adobe Reader. # LOD display is unsupported.
