OpendTect by dGB Earth Sciences

OpendTect is a free, open-source seismic interpretation system for visualizing, analyzing and interpreting 2D, 3D and 4D seismic data. It is also widely used for Geo-Radar interpretation. OpendTect is released under the GNU Public License (GPLv3 or higher).

OpendTect is also a software development environment for fast-track development of new plugins (in C++). Third-party developers can choose to develop under the GPL license. If so, derived products must be released as open-source plugins (copy-left principle). Alternatively, developers can opt to develop under the OpendTect Pro license agreement, which permits development of closed source plugins. Code developed in Python can be integrated into OpendTect. For more information, please have a look at our programmer's manual.
