The technique consists of an objective line generalization algorithm (Li-Openshaw algorithm) and an algorithm for the derivation of a new contour from two original neighbouring contours. The algorithms are implemented in such a way that they guarentee (a) no self-intersection within a line and no-crossintersection between lines ; (b) very smooth resultant contours and ; (c) very coherent relationship between resultant contour lines with very faithful shape to the original contours (at a larger scale). These conclusions have been supported by experimental tests. One of such tests was carried out through comparing the generalized results with the original contour lines and the other is through a comparison with a popular algorithm (Douglas-Peucker).
