摘要
介绍了从真实的电子海图中提取海洋地理信息数据,建立数据库,并转化成所需要的格式,分别存入海洋地理信息数据库的实现方法和步骤;根据这些数据库建立实体模型库,自动生成三维模型后建立三维模型库,最后实现了实体模型的动态装载.
This paper introduces the methods and steps for picking up ocean geographic information from an actual chart, conversing into reguested format and storing into ocean geographic information database. 3D model database is established based on these databases. Therefore the 3D model database is setup according to 3D models. Finally, dynamic loading of entity model is realized.
