r.mapcalc is unhappy because the map name isn't quoted internally
and it can't decide if the map name is a number or a name. I think
the same would happen if you had a "-" in the map name. If you
don't include the @mapset part it still runs, but the result
is no good as isnull(14) is always false if it thinks 14 is a
number.
quick work-around: rename the map to add a letter before the "14".
this bug is hopefully fixed in devbr6 with r48227, after testing
it should be backported to 6.4svn.
I am not sure if "$input" needs to be quoted or not in the
trunk python version:
#creating 0/1 map:
grass.mapcalc("$tmp1 = if(isnull($input),1,null())",
tmp1 = tmp1, input = input)
?

[GRASS-user] v.proj
Hi everyone, I'm using QGIS 1.7.0 and GRASS as a plug-in. I want to use v.proj to reproject vector files from another location. However when I open the location (B) where my reprojected vector file must be safed, I can't choose my input vector file because it is in location (A). Also when I open the (unprojected) vector file in location B, I can't select the file. Or when I open location A, I can choose the input vector file, but there is an error that I can't use 2 equal locations. How does this work? I have tried several options, but they don't want to work. Thank you.

[GRASS-user] areas with islands and v.generalize
Hi everyone, i'm trying to use v.generalize to smoothen polygon areas generated by r.to.vect. when using v.generalize in=cold out=cold_smooth method=douglas type=area thresh=0.1 the result remains the same as the input geometry. Leaving out "type=area" leads to smoothened results though islands become polygons. v.generalize in=cold out=cold_smooth method=snakes stops at 62%... any ideas how to solve this problem? thanks & best regards, Georg ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
