[GRASS-dev] [GRASS GIS] #3523: v.rast.stats: avoid multiple rasterization when run on multiple raster maps

Dear all,

I see that I somehow missed to apply this patch after Vero tested and before 7.6 release branch was tagged and Python 3 changes were committed.

My question now is, would it be OK if I apply the patch as is (since it is well tested) to svnreleasebranch_76 and a modified version (accounting for Python 3) to trunk?

Kind regards,
Stefan

Comment (by veroandreo):

 Tested with:

 {{{
 g.copy vector=zipcodes,my_zipcodes
 g.region -p vector=my_zipcodes align=elevation  v.rast.stats map=my_zipcodes raster=elevation,geology,soils  column_prefix=elev,geo,soil method=average  }}}

 I get a warning

 {{{

 and then I only see data for 13 polygons, instead of 44 as the warning  says...

 which makes sense since all maps queried are much smaller than the region  covered by the vector (See attachment). So, seems to work.
