DESCRIPTION

v.lrs.label generates LRS labels for pretty-printing of a LRS. This example is written for the Spearfish dataset (it continues the example from v.lrs.create).

v.lrs.label route_lrs rstable=route_lrs output=route_lrs_labels \
            labels=labels col=red size=50 xoffset=100

g.region vect=route_lrs n=n+100 s=s-100 -p
d.erase
d.vect route_lrs
d.vect route_lrs_labels col=grey type=line
d.vect busstops disp=attr attr=cat size=10 bg=white lcol=green yref=bottom
d.vect busstops icon=basic/circle fcol=green
d.labels labels
