Image Processing: Many new modules for creation of albedo, emissivity and vegetation index maps, TOA calibration, biomass growth and evapotranspiration estimation, image classification, hierarchical image segmentation, pansharpening, cloud detection in LANDSAT data, MODIS QA bitpattern management, graphical tool for Ground Control Points for geocoding imagery, Tasseled-Cap transform support for Landsat 8 and MODIS. The existing graphical user interface has been significantly improved and extended with new functionality not easily found in other GIS.
Histogram support in legends added and much more.
#PYTHON COMMANDS FOR GRASS GIS PORTABLE#
further binary packages for other Linux distributions will follow shortly.ĭisplay system and graphical user interface: New portable display system, used in the graphical user interface but as usual also with command line support. To get the GRASS GIS 7.0.0 source code directly from SVN, see here. GRASS GIS 7.0.0 also offers significantly improved performance for many raster and vector modules: "Many processes that would take hours now take less than a minute, even on my small laptop!" explains Markus Neteler, the coordinator of the development team composed of academics and GIS professionals from around the world.
As a stable release 7.0 will enjoy long-term support. GRASS GIS 7.0.0 ships 10,500 fixes and improvements with respect to GRASS GIS 6.4.0 after more than six years of development. Finally, there are a series of new modules to analyse raster and vector data some of the already existing modules were improved and made faster (some even 1000 x faster). A lot of effort has been invested to standardize parameter and flag names.
#PYTHON COMMANDS FOR GRASS GIS UPDATE#
This required a easy to manage topology format update including a new spatial index. Furthermore, the vector library was significantly improved to make it faster and more efficient, along with support of huge files. The developers added important new functionality to the core system, among that the new Python interface to the C library. This new API permits users to create new GRASS GIS-Python modules in a simple way while yet obtaining powerful and fast modules. The old Tcl/Tk based GUI has been dropped. The graphical user interface based on wxPython has been enriched with many new features in order to make complex GIS operations available as simple as possible. After many years of development the new stable major release GRASS GIS 7.0.0 is available.
