摘要: 提出了基于地形图数据库、地面巡视、地形图修测对原始数据和修测数据比对进行城市大比例尺地形图数据库地物变化自动识别的方法。这种方法效率高,准确性强,已成功用于北京市1∶500地形图数据库更新前地物变化的自动发现Abstract: This paperpr proposes a method to discover automatically feature change based on topographic map database, field patrol, topographic map surveying by compared the original data from database with the surveying data later. This method is of high efficiency and accuracy, and it is used to discover automatically features change before Beijing topographic map database updating on scale of 1∶500.
