Fimex is a the File Interpolation, Manipulation, and EXtraction library for gridded geospatial data

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, 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.

Virtual Token Descriptor for eXtensible Markup Language (VTD-XML)

Virtual Token Descriptor for eXtensible Markup Language (VTD-XML) refers to a collection of efficient XML processing technologies centered around a non-extractive XML parsing technique called Virtual Token Descriptor (VTD). Depending on the perspective, VTD-XML can be viewed as either an XML parser, a native XML indexer or a file format that uses binary data to enhance the text XML, an incremental XML content modifier, an XML slicer/splitter/assembler, or an XML editor/eraser.

Viking : A GTK2-based GPS data editor and viewer

Viking is a GTK2-based GPS data editor and viewer. It can download and show Terraserver 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).

GLE (Graphics Layout Engine) : A graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides

GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality graphs, plots, diagrams, figures, and slides. GLE supports various graph types (including function plots, histograms, bar graphs, scatter plots, contour lines, color maps, and surface plots) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.

Open Tool Kit (Otk) : A portable widget library for making graphical user interfaces for C programs

Open Tool Kit (Otk) is a portable widget library for making graphical user interfaces for C programs. It emphasizes simplicity for the application programmer without eliminating capability. Based on OpenGL, Otk supports Linux, Unix, and other OSs neutrally and efficiently. It is simple and compact, and it strives for easy compilation and linking to other applications. In seeking to address several issues associated with earlier graphics APIs, Otk explores some interesting methods, such as window-relative layout instead of pixel-based layout.

Social Networks Visualizer (SocNetV) : A flexible and user-friendly tool for the analysis and visualization of Social Networks

Social Networks Visualizer (SocNetV) is a flexible and user-friendly tool for the analysis and visualization of Social Networks. It lets you construct mathematical graphs with a few clicks on a virtual canvas, load networks of various formats (GraphViz, GraphML, Adjacency, Pajek, UCINET, etc), or create a network by crawling all links in a Web page. The application can compute basic network properties, such as density, diameter, and distances (shortest path lengths), as well as more advanced structural statistics, such as node and network centralities (i.e. closeness, betweenness, graph), clustering coefficient, etc.
