Nowadays, hiking and mountain climbing are beloved leisure time activities but various sports, such as orienteering and cycling, are also popular. The most frequent accessory of these activities is the map, which we can plan and follow our route with.

One of the drawbacks of maps is that they give only a top view, two-dimensional image of the terrain which encumbers the judgement of the difference in altitude when planning long path. This problem can be solved with a three-dimensional model which can be created from the contour lines of a map.

In my thesis, I present the image processing methods used to extract the contour lines, how I transformed the extracted contour lines into processable data and how I created the three-dimensional model. I introduce the issues I encountered during the task and the decisions behind the solutions to these problems.

I demonstrate the presented methods with a self-made graphical application. My thesis contains the design plans of this application as well. Furthermore, I introduce some commercial and free applications with similar functionality.
