2. GRASS GIS Geographic Resources Analysis Support System (GRASS) is a free and open-source Geographic Information System (GIS) software suite used for geospatial data management and analysis, image processing, graphics and maps production, spatial modeling, and visualization. It has powerful raster, vector, and geospatial processing capabilities. It can be used either as a stand-alone application or as a backend for other software packages such as QGIS and R or in the cloud. grass
3. QGIS A Free and Open Source Geographic Information System (GIS).
Create, edit, visualize, analyze and publish geospatial information on Windows, Mac, Linux, BSD, and mobile devices. It offers GIS tools for desktop, web, server, and mobile platforms.
4. GeoTools A library of Java code that allows users to build their own GIS. geotools
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
