Stanford Exploration Project Library (SEPlib) is a software package that was developed to manipulate and process many types of geophysical data. It includes libraries for manipulating 2D and 3D data and pipe-fed command-line utilities. It has support for parallelization through MPI and OpenMP and supports connectors to other geophysical packages.
ImageJ is an image processing program inspired by NIH Image for the Macintosh. It can display, edit, analyze, process, save, and print 8-bit, 16-bit, and 32-bit images. There are modules for biology, astronomy, nuclear medicine, physics, and more. If you can take a picture of something, whether with a microscope, a telescope, an oscilloscope, an xray machine, or a scanner, then this program will let you enhance, manipulate, and measure the results.
OpendTect is a seismic interpretation software system. It enables you to process, visualize, and interpret multi-volume seismic data using attributes and modern visiualization techniques such as stereo viewing and volume rendering. Visualization elements can be moved freely through data space to interactively analyze data from stored volumes, or data calculated on-the-fly. For more advanced work, commercial plugins are available.
Fieldtrip allows content experts to produce online e-case studies with limited support from computer and media specialists. Case studies include a group of events, each of which have a place (on a map) and a time (on a timeline), and can be associated with other media elements such as photos, animation, audio, and video. It is designed for students, researchers, and educators at the graduate and post-graduate level and for professionals and practitioners.
