<dt>snap_dist</dt>
<dd><p>A distance (float) given to find for each point its
nearest line in a spatial index. A too big value will produce
unnecessary distance calculations and a too short value will lead to
more iterations to find neighbours. In extrem cases, a too short value
could lead to points not associated with lines (index = -1).</p></dd>
