Visualizing spatial information on small mobile displays is a big chance and challenge at the same time. In order to address the tradeoff between huge spatial data sets and small storage capacities and visualization screens, we propose to visualize only the information on the screen which adequately fits the current resolution. To realize this, we automatically decompose the generalization of an object into a sequence of elementary steps. From this, one can later easily obtain any desired generalization level by applying the appropriate subpart of the sequence. The method method does not only lead to smooth transitions between different object representations but also is useful for incremental transmission of maps through limited bandwidth channels.
