The paper gives an overview, results and open issues in connection with a new approach to the problem of the automating the cartographic generalisation of contour lines. Research was conducted in several phases over almost a decade at the University of Zagreb’s Faculty of Geodesy. The properties of manually generalised contour lines on series of official topographic maps were analysed first. Based on the findings, new algorithms for simplification and smoothing were designed, with the distinct property of area preservation. Parameter values were also calibrated using contours from topographic maps, which enabled map scale to be defined as a primary parameter of the algorithms. Algorithms were first applied in the classroom, and later used in the production of topographic maps. The results prove that this approach can substantially improve the process of preparing contours for maps. Nevertheless, there is room for further improvements and future research. |
