Abstract. Since the project of dynamic updating of national fundamental geographic information database was launched, National Geomatics Center of China has published the newest version of multi-scale databases, derived databases and subdivision maps once a year. As one of the derived cartographic databases, administrative region index database allows users to find maps covering their regions of interest quickly by input the name or number of the relevant map. Due to the boundaries or attributes of some administrative regions may often change, updating of administrative region index database is necessary. To improve efficiency and quality in the national-level map production and database construction, an algorithm of administrative region index map automatic generalization has been proposed in this paper to replace the traditional manual production lines, which are time-consuming and uncontrollable in quality. The method goes in depth with handling coordinate recognition error accumulation and residue lines caused by the clip.
