results: on the left source data, on the right generalized data: it is possible to no-
tice a general reduction of the number of ditches and a more regular spacing among
them.
The algorithm produced some errors that leave space for future improve-
ments.
A couple of ditches running along the same road might be clustered and
typified together, with the new pattern being comprised of only one new
ditch, running exactly over the road among the original ditches. Such a
situation is not so uncommon and while the present algorithm will crop the
new ditch, a better solution should be found.
Another issue arises when the ditches in a group are connected to each
other by another ditch or hydrographic element (river, canal): if the shape
of the ditch envelope doesn't follow the shape of this connecting element
in the new pattern some ditches can be disconnected from it. Furthermore
if this element had an end connected to a ditch, this end might become
dangling.
