Hi devs,
Converting a vector to raster does in some specific cases yields yields
issues with the labeling. E.g., the following (example from NC dataset)
results in a layer with each raster cells assigned a category label (the
name of the municipality):
v.to.rast input=boundary_municp output=A01 use=attr attribute_column=OBJECTID
label_column=MB_NAME type=area
Running the following will give a raster in which a portion of the cells
do not have a label.
v.extract input=boundary_county where="NAME='WAKE'" output=WakeCounty
v.overlay ainput=boundary_municp binput=WakeCounty operator=and
output=WakeMunicp olayer=0,1,0
g.region vector=WakeMunicp res=100 -a
v.to.rast input=WakeMunicp output=A02 use=attr attribute_column=OBJECTID
label_column=MB_NAME type=area
I also tried:
v.extract input=boundary_municp where="COUNTY='WAKE'" output=WakeMunicp2
g.region vector=WakeMunicp2 res=100 -a
v.to.rast input=WakeMunicp2 output=A03 use=attr attribute_column=OBJECTID
label_column=MB_NAME type=area
Same results, some of the raster cells do not get a label. I guess I am
overlooking something here, but I can't figure out what goes wrong here.
Any ideas?
Regards
Paulo
