  • Platforms

    The GRASS source code is written in portable ANSI-C and is fully POSIX compliant. It runs on most known flavors of UNIX including Linux and Mac OSX, as well as MS Windows with Cygwin. Development is well underway on a native MS Windows port, with an experimental version available for download now. GRASS has been run on everything from supercomputers to handheld PDAs. It is well adapted for life on a single-user workstation, a large multi-user system, or application server and thin clients, with mapset-level access control. Cross platform GUI toolkits are used to ensure a consistent user experience regardless of the hardware. The old GUI used Tcl/Tk, the new GUI is using WxPython.

  • Image data processing

    The GRASS Development Team and members of the user community have collected numerous screenshots on these pages.

    Imagery data is treated as raster maps in GRASS, but there are a number of special modules specifically designed to help with image processing.

    For details, see the imagery and raster map processing guides.

    • Orthophoto processing: orthorectification of aerial photographs with new GUI tools, i.ortho.photo, i.points, i.vpoints, ...
    • Cluster analysis: i.class, i.cluster

  • Visualization and volumetric 3D examples

    The GRASS Development Team and members of the user community have collected numerous screenshots on these pages.

    GRASS includes the NVIZ visualization suite which is capable of rendering spectacular 3D snd 4D images and animations from 2D and 3D raster and vector maps.

    The keyframe animator in NVIZ can write directly to a MPEG or Xvid movie, or create a series of still frame images for use with another encoder. In addition, the r.out.mpeg module can be used to make a movie out of a series of raster maps.

    For details, see the NVIZ user manual.

    It is also possible to export GRASS 2D and 3D data to other powerful visualization software such as Paraview, MayaVi, and Vis5D+ using the VTK, V5D, and VRML output modules.

  • Cartography examples

    The GRASS Development Team and members of the user community have collected
    numerous screenshots on these pages.

    Cartography and journal quality figures are created using the specialist ps.map hardcopy authoring tool or directly from the main GIS displays using the PostScript,
    PNG, or Cairo drivers    . Use of the hardcopy display drivers may be automated
    with the d.out.file
    module. In addition GRASS data
    may be exported     for use in other popular mapping software such as GMT or Quantum GIS.
    Collaboration with external software is highly encouraged.
