Map generalization depends on many factors such as purpose, geographic scope, thematic, map scale and therefore it remains one of the challenging issues in Cartography. This paper discusses the constraint parameters and process of cartographic generalization from map data at 1:2000 to map data at smaller scale such as 1:, 1:, 1:, 1: and 1:. These constraint parameters are indentified by applying cartographic principles and using experimental procedures with generalization toolset in ArcGIS 10. Defined constraint parameters are then put in cartographic generalization for base maps of Ho Chi Minh City in order to verify their rationalities. Research result shows that, using right parameters and GIS cartographic generalization tools could provide good way to generalize and create base map products fast, efficient and reasonable. It also provides useful information for further research in automated map generalization and in creating multi-scale, multi-purpose map database. Keywords: Map generalization, multi - scale map, topographical map. 1. INTRODUCTION Map generalization plays an important role in the map-making process and it remains one of the challenging issues in Cartography nowadays because there are a lot of natural and social economic factors on the Earth's surface and they are not able to- be
