基于ArcSDE的内河电子航道图改正方法

Correction method of the inland ENC based on ArcSDE

为提高内河电子航道图数据更新的准确性和及时性,保证船舶航行安全.提出一种基于ArcSDE的内河电子航道图改正方法,利用ArcSDE可扩展关系数据库为空间可用数据库的特点,将内河电子航道图数据存储到空间数据库中进行处理.结果表明该方法提高了航道数据处理的效率.

In order to improve the data uptating accuracy and betimes of the inland ENC,and ensuring ships security when navigating.The paper proposed a correction method of the inland ENC based on ArcSDE,using ArcSDE's characteristic which can expand the relation database for the spatial available database,processing the inland ENC data was stored and processed in the spatial databases.The result indicates that the method can raise the fairway data processing efficiency.
