Open Source Data Management Systems

Viking is a free/open source program to manage GPS data. You can import, plot and create tracks, routes and waypoints, show OSM, Bing Aerial and other maps, geotag images, create routes using OSRM, see real-time GPS position (not in Windows), make maps using Mapnik (not in Windows), control items, etc. It is written in mostly in C (with some C++) & the GTK+3 toolkit. Viking is currently dual managed - with a corresponding Github presence at: https://github.com/viking-gps/viking Where you may find it easier to view the code and raise issues there too.

A real-time financial derivatives calculator supporting 171+ models from QuantLib, Financial Numerical Recipes in C++ and MetaOptions. Matrices of prices are created with iterating strikes and/or months. A strike control system can produce any strike. A generalized date engine can calculate re-occuring distances to any industry used expiration into the future. Spread engine with spread views. Models Supported: Black-Scholes, Merton-73, Black-76, Roll Geske Whaley, Garman KohlHagen, Jump Diffusion, Quanto, Vasicek Bond Option, Turnbull Wakeman Asian, TimeSwitchOption, Look Barrier, Bachelier, PartialTimeBarrier, GapOption, Extreme Spread Option, Simple Chooser, ComplexChooser, PartialFixedLB, Executive, CashOrNothing, Extendible Writer, OptionsOnOptions, BAWAmericanApprox, BSAmericanApprox, AssetOrNothing, Bisection, BAWbisection, BSbisection, Gfrench, Gcarry, Swapoption, Complex Chooser, Super Share, EquityLinkedFXO, Spread Approximation, BinaryBarrier and more

IIPImage is a high performance image server and client for viewing, navigating and zooming within high resolution images on the internet. Images in TIFF or JPEG2000 format are efficiently streamed by the server to a choice of clients that can be embedded within a web page.

The software package 'relax' is designed for the study of molecular dynamics through the analysis of experimental NMR data. Organic molecules, proteins, RNA, DNA, sugars, and other biomolecules are all supported. It supports exponential curve fitting for the calculation of the R1 and R2 relaxation rates, calculation of the NOE, reduced spectral density mapping, the Lipari and Szabo model-free analysis, study of domain motions via the N-state model and frame order dynamics theories using anisotropic NMR parameters such as RDCs and PCSs, the investigation of stereochemistry in dynamic ensembles, and the analysis of relaxation dispersion data.

Open-source, cross-platform 3D rendering engine for .NET and Mono. The Axiom Engine is a high-performance C# port of the powerful OGRE engine and provides full support for DirectX, OpenGL and XNA on Windows, Linux, Android, iPhone and Windows Phone.

NOTE: Code commits are FROZEN on SourceForge: New code is now at <http://github.com/Xastir/Xastir>. Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported. Linux/FreeBSD/Solaris/MacOSX/Windows in any of 7 languages. Can also be used for mobile mapping w/GPS. MAILING LISTS ARE AT: PROJECT->WEB SITE.

The OpenSceneGraph (OSG) is a cross platform C++, OpenGL based library for real-time visualization, with uses such as vis-sim, scientific modelling and games.

2D/3D Scene Graph rendering engine for Linux/Unix/Win32 layered atop OpenGL. Supports stereoscopy, volume rendering, 2D/3D texture mapping, picking, LOD and view-dependent operations, cross-platform text, constant-rate rendering and image-based data.

Free 3D Acropolis is a model 3D in hight resolution of the Acropolis of Athens shortly after its construction.

Mind map architect program is good tool for brainstorming for single person just as for team. Mind mapping tools can be usable for todo lists, notes, or work planning.

A command line tool for generating timing diagrams from ASCII input files. The input files use a structured language to represent signal state transitions and interdependencies. Raster image output support is provided by ImageMagick.

Software tools facilitating the task of surveying architecture (real-time control, parametric modelling, use of digital photographs, processing of point clouds...). Until now, those tools were mainly used to document cultural heritage sites/buildings

Easy encrypted backups over the Internet (a graphical user interface for Box Backup by Ben Summers and contributors)

Cellicone is a project to develop an artificial life organism with the necessary components to make it comparable to biological life as we know it. This includes components ranging from proteins to cells to organs to limbs, and many steps between.

Conic Planet is a CGI application which renders a photo-realistic real-time image of the Earth and other planets. It has support for Azimuthal, Mercator, Mollweide, Orthographic, and Rectangular projections. It also shows the current cloud covering.

EDAS2 is a web-based environmental quality data management and decision support framework

The Fung-Calc is an advanced, yet easy to use graphing calculator that supports graphing in both 2D and 3D. Several different plot types are available and graphs can be animated.

G2C (Geospatial to Civil) The LandGML Interoperability Experiment initiated by Autodesk, U.S. Army Corps of Engineers Engineering Research and Development Center, and Galdos Systems. this open source tool transforms LandGML into LandXML documents.

A high performance visualization tool for stars and particles able to run on Beowulfs. Rendering step is implemented separately and optimized for SSE, compatible with OpenGL. Navigation mechanism with quaternions. Ten color maps, sobel contour detect

InterferenceSimulator is a program demonstrating quantal two-slit Fresnel interference patterns with one, the other, or both slits open. A magnetic flux situated between the two slits allows demonstration of the Aharonov–Bohm effect. Simulations with short de Broglie wavelengths illustrate the classical limit of quantum mechanics. Because of the universality of wave phenomena, this program can also demonstrate the geometrical-optics limit of wave optics for small wavelengths.

Ledctl is a program written in C that uses the Parallel Port Interface(PPI) of the FreeBSD kernel to drive LEDs connected to the parallel port of a computer. It can be used within scripts to visually notify users for new mail, high processor load, etc.

Magneticle is a 3D OpenGL physical simulation that applies the Biot-Savart law to charged particles operating inside a magnetic field produced by a current-carrying wire modeled as an arbitrary space curve.
