Hi GRASS plugin users ;-)

+1 Pedro

GRASS plugin is definitely the most convenient way to access GRASS functionalities…
With plugin you have GRASS embedded in QGIS, you get the best of both worlds

Olá Paolo,

this will require a reasonable amount of work. I have raised the issue
several times; sadly it seems nobody is willing to invest the necessary
resources on this.

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?



BTW, would you mind giving us a list of the missing modules in
Processing? AFAIK these should be only obsolete and useless ones, but if
there is some genuinely missing we should be able to fix this rather easily.


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
