CHANGES IN GRASS GIS 7 compared to GRASS GIS 6
|
|
|
|
The graphical user interface based on wxPython (introduced in GRASS GIS
|
|
6.4) has been enriched with many 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 the most important the new Python interface to the C
|
|
library. This new feature 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 huge files. This
|
|
required a easy to manage topology format update including a new
|
|
spatial index. 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).
|
|
|
|
In total, more than 10,000 changes have been implemented so far with
|
|
respect to GRASS GIS 6.4.
