v.to.points creates points along input lines. It creates an output-dataset with 2 layers.
Layer 1 holdes information about the line-category and its attributes, layer 2 holds
information about the length line-category and its segment-length starting from the 0 to this point.
NOTES
The dmax parameter is the maximum limit but not an exact
distance. To place points with exact distance from the beginning
of the vector line the user should use v.segment.
EXAMPLE
In this example, the 't_powerlines' vector lines map in the Spearfish
location is used to create points along the input lines:
