【摘要】 针对组件式GIS应用系统中普遍关注的空间、属性信息交互查询功能的实现问题展开研究.对比分析了空间信息和属性信息等几种不同查询方式的实现过程;探讨了应用地理信息系统二次开发组件MapX构建系统时,提高查询效率的不同方法.同时,指出了在系统开发实践中采用MapX4.0进行属性信息查询时存在的问题,并给出了具体的解决方案.更多还原

【Abstract】 The research focus on the approach for realizing alternant query function between spaces and property in the application developed based on GIS components.Several different realizing processes of practical query methods from spatial information and property information had been contrasted and analyzed .Several ways to improve the query efficiency by using MapX as the component to construct a GIS system was discussed.Simultaneity,the practical problems of property query with MapX4.0 were pointed out,and the concrete scheme for solving these problems was also suggested.更多还原
