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
