RESEARCH ON NATIONAL 1:50000 TOPOGRAPHIC CARTOGRAPHY DATA ORGANIZATION
Database-driven cartography technology is just appeared in China.In China,it”s the first time to use this technology in such a large national terrain information database.Especially in the particular 1:50000 scale,it will face a more complex situation.To effectively address the problem,with the database-driven cartography mechanism,it is very necessary to design scientific and rational model for data organization and presentation mechanisms,to ensure that the rich geographic information of terrain data can be expressed correctly,completely and beautifully in the topographic map.This paper mainly introduces the general design of data organization model of the cartography data.It also designed and developed national 1:50000 topographic cartography production system,and gave out related application example as a test of the idea mentioned.The application example proves that the data organization model designed here is feasible and efficient in nation 1:50000 topographic map production,and greatly reducing the workload of manual editing.
