基于GeoDataBase的面向对象的地质数据模型设计

本文阐述建立基于GeoDataBase的地质教据模型的的方法,以1：50000中华人民共和国地质图所包含的地质内容为例,通过分析地质数据,划分要素类,定义和描述各要素类和关系类,最终利用Visio2003中建立完整的面向时象地质数据模型UML模型。由此模型使得地质资料数据的组织更为合理,使得地质数据库能够更好地服务于地质应用领域;同时,模型的研究也期望能为国土资源管理的信息化建设做一些有益的基础研究工作。

Design the Object-oriented Geologic Data Model Based on GeoDataBase

This paper elaborated the method and process of the establishment of the geologieal data based on GeoDataBase,taking 1：50000 geological map People＇s Republic of China for example, by analyzing geologic data, and separating feature class ,defining and describing the feature class and relationship class,ultimately we built a complete object-oriented geological UML model with Visio 2003.Thus this geologic data model makes the organization more reasonable and makes geologic database to better serve the geological applications, at the same time,the study of model is useful to information construction to the management of land and resources.
