| 摘 要： | 设计主动式地理信息服务质量(quolily of active geospatial information service,QoAGIS)评估系统,阐述主动式地理信息服务的内涵及其逻辑结构,提出AGIS质量评估指标的概念,并对其中的本征质量指标与广义质量指标的定量化实现进行研究,给出综合评估指标.最后,通过实验表明QoAGIS评估系统的适应性和可靠性.Abstract：Currently, the passive aspects of geospatial information service (GIS) and the unpredictability of QoGIS are unable to meet the applications in some deeper fields. A new evaluation system of quality of active geospatial information service (QoAGIS) is presented. The connotation and logical structure of AGIS is analyzed, in which it advanced basic event and its expression, event operation's methods, the expression of complex event and the driven rules, the indices of QoAGIS evaluation are presented, in which the intrinsic quality index and the generalized quality index are researched on. Finally the compositive evaluation index is calculated. The QoAGIS evaluation system has been used in an application of AGIS, the experiment indicated its adaptation and reliability.

| Abstract: | Currently, the passive aspects of geospatial information service (GIS) and the unpredictability of QoGIS are unable to meet the applications in some deeper fields. A new evaluation system of quality of active geospatial information service (QoAGIS) is presented. The connotation and logical structure of AGIS is analyzed, in which it advanced basic event and its expression, event operation's methods, the expression of complex event and the driven rules, the indices of QoAGIS evaluation are presented, in which the intrinsic quality index and the generalized quality index are researched on. Finally the compositive evaluation index is calculated. The QoAGIS evaluation system has been used in an application of AGIS, the experiment indicated its adaptation and reliability. |
