[Qgis-developer] QGIS and GRASS 7.0.0

Despite the great advantages of GRASS commands in Processing, I think that
the GRASS plugin still plays an important role and is an excellent
interface for GRASS. For those who still like to use the paradigm of
locations, mapsets and the GRASS topological model, GRASS plugin is very
important, because then it allows to use all QGIS tools, for example, to
create layouts using the Composer, etc.

If no one is interested in making the port of the plugin for GRASS 7, we
could try through a crowdfounding initiative. Who was behind the initial
creation of GRASS plugin?

I've been checking the differences and they are indeed few. Please see the
spreadsheet attached.

Some commands seem that were adaptations of other algorithms, made for
Processing, as they are not in the 6 manual, or in the 7:
r.cost.full.raster, r.drain.coordinate, r.terraflow.short,
v.surf.rst.cvdev.line, v.surf.rst.line, v.transform.pointsfile.

Others seem that have been removed from GRASS 7 (r.average, r.bilinear,
r.bitpattern, r.surf.idw2), as they are not in the GRASS 7 manual.

There are five that seem important to me, which are in GRASS 7, in
Processing GRASS 6, but not in Processing GRASS 7: r.out.xyz, r.ros,
r.spread, r.univar, v.kernel.

Finally, there are two commands that are on GRASS 7 and were not in 6:
r.viewshed (which replace r.los) and r.relief (which replace
r.shaded.relief).


Thanks!

Best regards,
Pedro Venâncio
