| 7 | | The graphical user interface based on wxPython (introduced in GRASS GIS 6.4) has been enriched with many '''[wiki:Grass7/NewFeatures new features]''' in order to make complex GIS operations available as simple as possible. The old !Tcl/Tk based GUI has been dropped. Relevant new features are available in the core system, among that most importantly the [http://grass.osgeo.org/grass70/manuals/libpython/pygrass_index.html new Python interface to the C library]. This new API permits Python developers to create new modules in a simple way while at the same time creating powerful and fast modules. Furthermore, the vector library was particularly improved to make it faster and more efficient with support of [http://grasswiki.osgeo.org/wiki/Category:Massive_data_analysis huge files]. This requires an [http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7 easy to manage topology format update] including a new spatial index. A major cleanup of the parameter names helps the users to easily implement their workflows. 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). For details see below. |

The developers have added important new functionality to the core system, among that the [http://grass.osgeo.org/grass70/manuals/libpython/pygrass_index.html 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. Furthermore, the vector library was significantly improved to make it faster and more efficient, along with support of [http://grasswiki.osgeo.org/wiki/Category:Massive_data_analysis huge files]. This requires an [http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7 easy to manage topology format update] including a new spatial index. A lot of effort has been invested to standardize parameter and flag names. 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). For details see below. |
