[GRASS-user] r.li.setup in GRASS 7

GRASS GRASS user

Hi Grass User,

I’m using GRASS 7 ( revision 53178) and I would like to compute some landscape metrics (mean patchs size, density…).
But there’s no r.li.setup in GRASS 7, so I wan’t to know if there’s a workaround or another way to use r.li or even r.le in GRASS 7 ?

Cheers

Luca Delucchi is working on it:
http://trac.osgeo.org/grass/browser/sandbox/lucadelu/r.li.setup.py

If you want to trey, at page bottom:

   --> Original Format

However, a few things are still missing which shall be added within
a week or so.

Thank’s a lot Markus.
I tried it but I’m not able to create a good conf file (compare my movwindow3_new produced by r.li.setup.py and movwindow3 produced in GRASS 6.4 long time ago)

When I tried r.li.patchdensity (or another r.li.*) I end up with this error
(I tried to reproduce one example of the GRASS 2008 book on p.154)
r.li.patchnum input=forest1996@user1 config=movwindow3_new output=forest_p_num3_new
ERROR: Illegal configuration file (sample area)

I don’t have enough skills in this area to help so I’ll have to wait a few week (when this addon will be finished and added) and use R for the time being.

Thank’s again for your time

I committed right now r.li.setup gui for wxpython. It's possible to
launch from GUI "raster -> Landscape path analisys -> Set up....." or
from command line using g.gui.rlisetup. Missing feature should be
added in the next months and testing is welcome.
I already know a bug if you launch more times the wizard from the
second time you can move forward without the name of configuration
file and raster that are mandatory. If someone can help me for this
point....
