| 摘 要： | 本文根据面向对象空间数据模型的相关概念和特点,将地理空间中的空间行为进行建模后纳入面向对象空间数据模型的框架中。面向对象空间数据模型由数据模型和空间行为模型两个部分组成:数据模型包括空间特征数据和属性特征数据;同时将空间行为模型分为两大类,即静态空间行为模型(地理目标间关系)和动态行为模型(地理目标行为)两部分。在此框架提出的基础上,本文利用二进制、XML流等格式文件对该空间数据模型进行了整合和组织。 |

| Abstract: | According to the conception of the object-oriented model in the computer field,this paper modeled the spatial behavior of objects in the spatial space,and integrated the spatial behavior into the object-oriented spatial data model in terms of construct and particular of object-oriented spatial data model.Object-oriented spatial data model is consisted of data model and spatial behavior model.Data model includes spatial data and attribute data,while spatial data model can be divided into two parts which are static spatial behavior model(object relationship) and dynamic spatial behavior model(object behavior).Object relationship includes inheritance relationship,general relationship and spatial relationship which is composed of three main spatial relationships(topological relationship,directional relationship and distance relationship).And object behavior infers to the process of simulation of the spatial objects and presents the GIS analysis function of spatial object in geographic space.Meanwhile based on this framework,this paper integrated and constructed the object-oriented spatial data model with binary file and XML file. |
