Automated generalization of present land-use map patches

LI Ying;ZOU Zheng-rong;Department of Surveying and Geo-informatics,Central South University;  
The paper analyzed the influencing factors on automated generalization of present land-use map patches using the combination of semantics and spatial analysis. According to the impact of these factors,it processed the land-use polygons in the map with merging,mixing and aggregating. Ningxiang County in Changsha was taken as an example for experiment,and the result showed that this method could maintain the structures of different land classes before and after generalization in Ningxiang county,reflect the landuse distribution well and save a lot of work load.
