Parameters:
- vector=name [required]
- Name of input vector map
- Or data source for direct OGR access
- cat=integer [required]
- Category of a vector line
- dir=name [required]
- Directory where the output will be found

v.fixed.segmentpoints creates segment points along a vector
line with fixed distances by using the
v.segment module. A
category of one line has to be given. Start and end point of the line
will be considered. The distance option is limited to an integer number.
As a
prefix (starting with a letter) has to be given, resulting
vectors are
prefix_singleline and
prefix_segmentpoints, resulting external files are
prefix_segmentpoints and
prefix_segmentpoints.csv.
The next to last point may be closer to the last point as the given
distance. Distance information for every point is added to the vector
attribute table. The attribute is then exported as CSV file.
The category (cat) of the input line is stored in the column
cat_line of the prefix_segmentpoints attribute table.
