Updated releases

 

Release distribution

Geocap 7.0 is available from http://www.geocap.no/downloads to all clients under paid maintenance agreement. 
Please note that you will need a user account to access this page. If you do not already have one, send an email to: support@geocap.no

Licensing

Installing a new license file: See our FAQ page and the document Installing on Windows.

Important

 All clients will need a new license file in order to run Geocap 7.0. We will send new license files to all our clients under paid maintenance agreement. If you have not received a license file please contact us at support@geocap.no

Important

Geocap 7.0 uses a new resource folder, geocaprc-7, usually found in a folder structure similar to C:/User/<Username>/geocaprc-7/. If there are userscripts, startup scripts, color tables or shared commands you need, these will have to be imported over again. Userscripts may be copied from the previous geocaprc-6.4

You have to do the following before starting Geocap 7.0 for the first time:

Windows 7:
Start > All Programs > Geocap-7.0.x - xx  > Licensing and right-click Initialize 7.0, then click Run as Administrator. 

Windows 8.1:
Start screen > Apps view > Search for 'Geocap' > Right-click Initialize 7.0, then click Run as Administrator. 

Supported operating systems

Geocap 7.0 runs on Windows 8.1, 8 and Windows 7. Both 32bit and 64bit versions of Geocap 7.0 are available on our download page. Both versions can be installed at the same time and projects can be used in both versions. In order to use the DataLink for ArcGIS you need to run the 32bit version. Consult this Microsoft support page to figure out which system type your are running on. 



Project upgrade

All projects opened in Geocap 7.0 will all be irreversibly converted to a new project format. We highly recommend that you back up your projects prior to opening them in Geocap 7.0.


Highlights

1. Water Column Data 

In the Seafloor module we now launch the import, vizualisation and interpretation of Water Column data. Water column data are collected by multibeam echo sounders and is represents bacscatter in the watercolumn between the echo sounder and the seabed. Currently Geocap can read data from *.all and *.wcd files (from Kongsberg Maritime) only.

Geocap is using the same vizualisation technique for water column data as for the seismic data (brick technology).

The new commands in the Seafloor module:

  • Import Multibeam Water Column Data: Read water column data after reading the depth data for the corresponding survey file.

  • Display Water Column Swath: Display water column data (swath) from selected dataset(s).

  • Extract Water Column Points: Analyze and filter the water column data and extract interesting features. This function is dependent on the seafloorwci feature in the license file. 

  • Display Water Column Points: Display the extracted points and use a tool for interactively changing the colour and visibility of the water column points. This function alseo need the seafloorwci feature in the license file.

2. New Depth Conversion Concept 

It is now possible to generate a velocity model in Geocap using the new command Generate Velocity Model. At this point there are four different types of velocity models available:

  • Constant ground velocity

  • Layer velocity model

  • RMS velocity model

  • Average velocity cube

Once the velocity model has been generated it can be used as input to the depth conversion in the new Velocity Model Depth Convert command. The command can depth convert the following datasets:

  • Seismic 2D lines

  • IHorizons (seismic interpretations)

  • Poly Data (points, lines, polygons)

  • Gridded horizons / surfaces (structured points)

 

3. Auto save and project save as.. 

You can now set up Geocap to automatically save your projects with specific time intervals. The option is available under Tools > Options > Projects

It is now possible to save your project with a different name using the new Save As option

4. Surface Cut/Fill volumetrics 

The new command Surface cut/fill volumetrics is a new tool to easier calculate volume between two surfaces or between a surface and a set of polygons describing a cut surface.
The command will calculate the volume to cut and fill and the corresponding horizontal area for each, and write to a report saved in a Reports folder.
