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.
Quantum GIS (QGIS) is a cross-platform Geographic Information System (GIS). It offers support for vector and raster formats, including spatially enabled tables in PostgreSQL using PostGIS, common GIS vector formats such as Shapefiles, and geo-referenced rasters (TIFF, PNG, and GEOTIFF). Many plugins are available to dynamically add new functionality. Viewing of GRASS layers (vector and raster) is provided by a plugin. GRASS vector layers can be edited in QGIS.
GraphPak is a programming library of 2D and 3D charting objects for the Qt toolkit. It provides software developers with a set of C++ objects to easily create charts or graphs that aid in the visual presentation of technical and business data. This release includes Bar, Line, Pie, Ring, Area, Hi-Lo, Box and Whisker, and Polar charts. It is based on the KD Chart product from Klarälvdalens Datakonsult AB.
McIDAS-Lite is a freely available demo for the full McIDAS software. It will connect to a variety of free online data sources for satellite data and display the images in a viewing window. Images can be looped and analyzed, and graphics overlays can be created to show maps and other geographical features. It is available for AIX, HP-UX, Irix, Linux, Mac OS X, Solaris Sparc, Solaris x86, and Windows XP with SFU.
STARS is an exploratory data analysis package designed for variables measured for geographical units over time. It combines a series of statistical graphics and mapping views together with some newly developed measures for space- time statistical analysis. It also includes utility methods for creating different types of geographical weight matrices, variable transformations, and for reading ArcView shapefiles to develop related projects.
J2ME OGC WMS Client is a program for accessing OGC Web map services from Java enabled mobile phone or PDAs. It accesses the OGC WMS according to WMS 1.1.0 and 1.1.1 specifications and supports zooming and panning in the Map, WMS sublayers, and a bookmark management system for quick access.
Earth3D visualizes the earth in realtime in a 3D view. One can rotate and zoom the view and fly around. Additional data layers can be added to the view, e.g. country flags and names. It uses data from NASA, USGS, the CIA, and the city of Osnabrück. The data is loaded on demand over the Internet.
