摘要：It is one of the important ways for GIS data updating based on map generalization. This paper analyzes the main steps for road data updating based on map generalization. As the core of this updating process, matching method considering the levels analyses and selective omission based on mesh density are developed. The approach for road data updating based on these two tools is proposed, which is applied in the project of national GIS data updating at 1:50,000 scale from data at 1:10,000 scale ant the results shows its feasibility
