| 5. | gvSIG Association | gvSIG Online is the integral platform for the implementation of Spatial Data Infrastructures (SDI) and corporate GIS in free software. It allows to share geographic information in the cloud, generate maps in 2D and 3D applications easily. | gvsig |
| 6. | OpenJUMP GIS | It is an open-source, desktop-based GIS written in the Java programming language, originally developed by Vivid Solutions. The current version can read and write shapefiles simple GML files as well as several other vector formats via plugins. It can also read from several spatial databases and write to postgis. It has support for images and for WFS and WMS web-services. So you can use it as GIS Data Viewer. However, its particular strength is the editing of geometry and attribute data. One can style the appearance of data in OpenJUMP’s map display and can export the view to SVG. A growing number of vector analysis tools for topologic analysis and overlay operations are available too. | openjump |

| 8. | Flowmap | Flowmap is a software package dedicated to analyzing and displaying interaction or flow of data. It allows users to visualize relationships between two points. Flowmap is a PC software package (Windows 95/98/2000/ME/XP and will in most cases also work within Windows Vista and Windows 7), developed at the Faculty of Geosciences of the Utrecht University in the Netherlands. | flowmap |
| 9. | GMT | Generic Mapping Tools is a collection of tools for creating GIS maps and animations. GMT is an open-source collection of command-line tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing high-quality illustrations ranging from simple x–y plots via contour maps to artificially illuminated surfaces and 3D perspective views. It supports many map projections and transformations and includes supporting data such as coastlines, rivers, and political boundaries, and optionally country polygons. | gmt |
| 10. | SPRING | SPRING is a state-of-the-art GIS and remote sensing image processing system with an object-oriented data model which provides for the integration of raster and vector data representations in a single environment. It was developed by Brazil’s National Institute for Space Research. SPRING’s main features are an integrated GIS for environmental, socioeconomic and urban planning applications. A multi-platform system, including support for Windows95/98/NT/XP and Linux. A widely accessible freeware for the GIS community with a quick learning curve. |
