DESCRIPTION

v.label.sa makes a label-file from a GRASS vector map with labels created from attributes in the attached table. The labels are placed in as optimal place as possible. The label file has the same syntax as the one created by v.label

EXAMPLE

Spearfish example: 

d.font -L
v.label.sa roads font=Vera labels=roads_labels column=label
g.region vect=roads
d.erase
d.vect roads
d.labels roads_labels
