摘要 作者报告了一种新颖的空间分析系统接口，它允许使用高级、面向特征或面向对象的模型来表示底层地理域。该系统采用了智能、数据驱动的报告技术，可分析领域特征以突出显着趋势。第二个新颖的功能是使用扩展数据模型中保存的数据来实现查询优化。该界面基于面向对象的技术，该技术已得到增强，可以捕获上下文数据和知识，包括数据行为的一般模式、一般地理知识和数据库领域特定的特征。当地理信息系统能够以空间和以对象为中心的方式处理搜索时，它可以提供更大的灵活性。我们当前的工作涉及提高以对象为中心的方法的功能和效率，从而提高地理信息系统的有效性......
Abstract The authors report a novel interface to a spatial analysis system which allows the underlying geographical domain to be represented using a high-level, feature-or object-oriented model. The system incorporates an intelligent, data-driven reporting technique which analyses the domain characteristics in order to highlight significant trends. A second novel feature is the use of data held in our extended data model for the purpose of query optimization. The interface is based on object-oriented techniques, which have been enhanced to capture contextual data and knowledge, including general patterns of data behaviour, general geographical knowledge and database domain-specific characteristics. A geographical information system can offer more flexibility when it can handle searches in both a spatial and object-centred way. Our current work is concerned with increasing the functionality and efficiency of the object-centred approach, and hence increasing the effectiveness of geographical information sys...
