maximum distance between points in SPDF and the
polylines in SLDF, for these to be considered for poyline splitting
splitPolyline obtain the closest points in the SpatialLinesDataFrame to a
given input set of points. Those closest points are used to divide the
polylines in a number of transects. The individual transects are
clipped to the input point dataset, so the different transects are
continuous in space. Note that if the input points is quite appart
from the polyline, the output sequence of transects may substantially
differ form the input polyline at rupture zones. The input parameter
dmax is provided as a mean to avoid too strange splitting
results. Setting dmax to a ver low value will reduce the spureous
results, but also the input points need to be closer to the lines for
the adequate recognition of splitting points
