Abstract
Geo-spatial data updating based on map generalization is one of the important ways for GIS data updating.This study is focused on the approach for road data updating based on map generalization.The selection method for road data based on mesh density and road matching method considering the levels analyses is proposed for this procedure.This approach is applied in the project of national GIS data updating at 1∶50 000 scale,and the results shows its feasibility.
