Fimex is a the File Interpolation, Manipulation, and EXtraction library for gridded geospatial data. It converts between different, extensible data formats (currently netcdf, NcML, grib1/2, metgm, wdb, and felt). It enables you to change the projection and interpolation of scalar and vector grids. It makes it possible to subset the gridded data and to extract only parts of the files. For simple usage, Fimex also comes with the command line program fimex.

Gwyddion is a modular SPM (Scanning Probe Microsope) data visualization and analysis tool. It can be used for all most frequently used data processing operations including: leveling, false color plotting, shading, filtering, denoising, data editing, integral transforms, grain analysis, profile extraction, fractal analysis, and many more. The program is primarily focused on SPM data analysis (e.g. data obtained from AFM, STM, NSOM, and similar microscopes). However, it can also be used for analyzing SEM (scaning electron microscopy) data or any other 2D data.

SCaVis is an environment for scientific computation, data analysis, and data visualization designed for scientists, engineers, and students. The program can be used for function and data plotting in 2D and 3D, histograms, statistical analysis, and symbolic calculations using the Matlab/Octave high-level interpreted language.

xylib is a portable C++ library for reading files that contain x-y data from powder diffraction, spectroscopy, or other experimental methods. Supported formats include plain text (CSV or TSV), Crystallographic Information File for Powder Diffraction (pdCIF), Siemens/Bruker UXD, Siemens/Bruker RAW v1/2/3, Philips UDF, Philips RD (raw scan) V3, Rigaku DAT, Sietronics Sieray CPI, DBWS/DMPLOT data file, Canberra MCA, XFIT/Koalariet XDD, RIET7/LHPM/CSRIET/ILL_D1A5/PSI_DMC DAT, Vamas ISO14976, and Princeton Instruments WinSpec SPE.

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.

jHepWork (jWork) is an environment for scientific computation, data analysis, and data visualization for scientists, engineers, and students. The program is fully multi-platform (written in Java). Programs can be written in the Java, Jython/Python, and BeanShell scripting languages. Matlab/Octave is supported for symbolic calculations. The program can be used to display data and functions in D and 3D. It comes with a friendly IDE and a code assist.

FísicaLab is an educational application to solve physics problems. The problems are set up by adding elements from the palette to a chalkboard and entering the data for each element. The elements are objects such as blocks, pulleys, motors, and forces. It can use the SI and English unit systems, scientific notation, and many conversion factors. The types of problems that can be solved are kinematics of particles (including circular motion), static analysis of particles and rigid bodies in 2D, dynamic analysis of particles in 2D (excluding the dynamics of circular motion), heat, calorimetry, ideal gas, and expansion. The static and dynamic problems are entered by constructing the free body diagrams of the objects.

libquantum is a C library for the simulation of quantum mechanics, especially for quantum computing. It provides an interface for a quantum register and for all important quantum operations. An efficient model for decoherence allows an analysis of quantum computation in a realistic environment.
