OpenEV is a library and reference application for viewing and analysing raster and vector geospatial data. OpenEV capabilities include the following: handling of raster and vector data, support for 2D and 3D display, graceful handling of very large (gigabyte) raster datasets, support for multi-channel raster datasets, understanding and interpreting of georeferencing information, pan/zoom/rotate at interactive frame rates (using OpenGL), and a powerful image analysis tool (using Numerical Python).
OpenMap is a JavaBeans-based GIS toolkit for building applications and applets needing geographic information. Using OpenMap components, you can access data from legacy applications, in-place, in a distributed setting. At its core, OpenMap is a set of Swing components that understand geographic coordinates. These components help you show map data, and help you handle user input events to manipulate that data.
OpenVRML is a VRML and X3D browser plug-in and C++ toolkit for incorporating VRML/X3D support into applications. It provides VRML97 and Classic VRML X3D parsers, a runtime, and an OpenGL renderer as C++ libraries. The renderer is fully separate from the runtime library so that users can also provide their own renderer. The OpenVRML browser is provided as a D-Bus service, and is embeddable in host applications using XEmbed. The distribution provides both a stand-alone host and a host that runs as a Mozilla plug-in.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
Plotter is a GTK+ mathematical graph plotting application. It is written entirely in Python using the PyGtk bindings. Features of Plotter include plotting of cartesian, parametric, and polar equations. An unlimited number of plots can be displayed in individual colours. Plotter supports graph zooming and panning, and loading and saving of sets of graphs. New functions can easily be added from within the program.
KMatplot is an Origin-like tool for plotting data sets in either two or three dimensions. It can plot many ordinary types of 2D plots, including pixmaps, contours, and 3D surfaces. It offers a full WYSIWYG mode with many graphs on a single page and a simple command interface for Octave and Scilab.
R is a language and environment for statistical computing and graphics. It is similar to S, which was developed at Bell Laboratories by John Chambers et al. It provides a wide variety of statistical and graphical techniques (linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc.). R is designed as a true computer language with control-flow constructions for iteration and alternation, and it allows users to add additional functionality by defining new functions. For computationally intensive tasks, Fortran and C code can be linked and called at run time.
Robochart makes drawing all types of flow diagrams, such as data flow diagrams, UML, flow charts, and org charts fast and easy. Drag and drop shapes and lines from a large library, add text in selectable fonts and colors, and modify the diagram with direct manipulation. Output formats include PostScript, MIF. and HTML with images and maps.
