ABSTRACT

An alternative way of pursuing digital map generalization is to start with an interactive system. The digital map generalization system MGMG is intended to replace time-consuming and fully operator-dependent manual map generalization. The experiment presented is an example of formalizing a generalization process to achieve a target output. Manual generalization actions can be considered to consist of the following nine categories of operations which become the major functions in MGMG design. To formalize a generalization workflow using the existing product with the available functions and tools, the aspects discussed should be taken into account. An experimental project was carried out to establish a potential workflow for generalization of topographic data. Most of the intermediate results for vegetation data are shown, while only a couple of significant intermediate results for other features are given due to the limited chapter length.
