ABSTRACT
Development of cycle routes in Poland is a frequently discussed topic. This type of infrastructure
may be designed using a variety of methods. Manual planning of new cycle paths based on aerial
laser scan data is relatively quick and also precise. The ALS technique can provide the required
accuracy of design map in terms of elevation measurements. It is worth noting that only a few
years ago studies indicated that elevation measurements were less accurate when using this par-
ticular technique [Hejmanowska, Warchoł 2010]. The designer has a detailed insight into the
studied area. He may easily assess the terrain and choose the optimal location for the given
object. Planning the route course and its elevation variability is simple when using a Digital
Terrain Model.
The first stage of the present study analyses the rules that apply to bicycle route design and the
area covered by the study. The course of the new cycle path was planned in such a way as to con-
nect the most important places in towns as well as places of tourist interest. The resultant route
is 1.8 km long and runs along the main road. Development of DTM and its visualizations were
performed mainly on the basis of two point clouds provided by the Geodetic and Cartographic
Documentation Center. The initial works were performed in MicroStation PowerDraft V8i soft-
ware. In the next stage, a 3D visualization of the model was generated with the use of Surfer 11
program. Based on that, a longitudinal profile of the route was created.
