ability in single maps (see Fig.
19.2, example ‘protection status’). After that, the
criteria were weighted by their relative importance for greenway implementation
and an overall suitability map was created.
3. Delineating the most suitable routes. The suitability assessment was the basis
upon which the LCP algorithm was used to delineate the most suitable routes
between the demand areas. The results of a first run of the model was discussed
with local planning officials to evaluate its validity within the Oranienburg con-
text. The discussion showed some deficits in the results and led to a modified
second model run, leading to an adjusted greenway network (see Figs. 19.3 and
19.4 for the results of both model runs).
The resulting greenway network fulfilled the intended functions of alternative
travel provision and nature protection to a large extent. However, although some
constraints of the first network (e.g. physical barriers not considered by the model)
could be eliminated by the second one, this still includes some undesirable trade-
offs, such as route alignment along main roads. Besides reflecting some imperfect
weight allocations within the model, this is mainly a consequence of the scarcity of
suitable sites which limited routing options – certainly not only a problem in
Oranienburg, but found in most cities. This can be regarded as a major challenge
and a problem to be overcome by landscape planners on the one hand, and as a fact
which should lead to realistic expectations and compromises on the other hand.
