EDFbrowser is a multi-platform viewer for EEG, EMG, and ECG storage files. It supports the EDF, EDF+, BDF, and BDF+ file formats. It supports montages, annotations, precise measurements by using crosshairs, and a zoom function by drawing a rectangle with the mouse. It shows signals from different files at the same time. It includes a built-in EDF/EDF+/BDF/BDF+ to ASCII converter, a built-in Nihon Kohden to EDF+ converter (including annotations), a built in EDF+D to EDF+C converter, a BDF(+) to EDF(+) converter and a built-in EDF/EDF+/BDF/BDF+ compatibility checker.
GRAL is a library for creating high quality plots and charts in Java. Many plot types are available like scatter plot, bubble plots, line plots, area plots, pie charts, and bar charts. Additionally, GRAL can exchange and process data (smoothing), and various plug-ins allow the import and export of data and graphics to formats like CSV, JPEG, PNG, EPS, PDF, or SVG.
SaVi is satellite visualization software that lets you create, run, examine, and modify satellite orbits in two and three dimensions. Simulations of Iridium, Globalstar, Galileo, GPS, and other satellite constellations are included. SaVi requires Tcl and Tk on a system with Unix libraries. SaVi works well with the 3D renderer Geomview. Geomview is optional, though recommended for its 3D rendering capabilities.
Gmsh is an automatic 3D finite element grid generator with built-in CAD and post-processing facilities. Its design goal is to provide a simple meshing tool with parametric input and advanced visualization capabilities. It is built around four modules: geometry, mesh, solver, and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface (based on FLTK and OpenGL) or in ASCII text files using Gmsh's own scripting language.
GetDP is a general finite element solver using mixed elements to discretize de Rham-type complexes in one, two, and three dimensions. The main feature of GetDP is the closeness between the input data defining discrete problems (written by the user in ASCII data files) and the symbolic mathematical expressions of these problems.
Viking is a GTK2-based GPS data editor and viewer. It can download and show OpenStreetMaps, Terraserver, and other maps, import and draw tracks and waypoints over them, add coordinate lines, make new tracks and waypoints, hide different things, and more. It uses a hierarchical layering system to organize GPS data, maps, and other layer types with spatial data (such as coordinate lines).
peak-o-mat is a data analysis and curve fitting program. It was designed to fit spectroscopic data but should be suited for any other fitting task. It allows for clearing, transforming, fitting, calibrating, etc. of spectra with few mouse clicks. It can be scripted using the Python language and can be extended by writing modules.
Veusz is a scientific plotting package, designed to create publication-ready Postscript, PDF, or SVG output. It features an easy to use graphical interface as well as a command line interface and can be scripted or embedded in Python scripts. Graphs are constructed in a modular fashion from separate components. Datasets can be interactively modified or created from within the program.
