A name extraction method and its implementation for area river features based on DLG maps

LEI Yuting;LI Linyan;Suzhou Smart City Planning and Research Application Center;College of Information Technology,Suzhou Institute of Trade & Commerce;  
There is rich and abundant information about rivers and lakes on the DLG maps. But river features displayed on DLG maps,including geometrical figures and annotations,are separated from each other. The river names cannot be extracted directly from DLG maps because each river annotation contains only one characteris-tic. After analyzing the arranging rules of river annotations,we proposed a clustering method based on the distances between river annotations to extract complete river names. We implemented river annotations on DLG maps related to Suzhou urban area and confirmed its feasibility.
