| 摘 要： | 为了满足城市GIS中高效查询、规划设计、应急处理及社会化服务的应用需求, 采用地名数据库、管理及搜索引擎、维护及搜索工具三层架构, 设计和实现了一个通用的城市GIS地名定位工具.该定位工具兼顾点状要素和区域范围, 提供建库、维护、搜索、移图等功能, 支持快速模糊匹配.结果表明: 城市地名数据库便于建立和更新, 不仅使UGIS系统能快速将关注区域移动到指定地点, 还是一种要素类的表达方式, 可以为高级的查询和分析提供数据基础.

| Abstract: | In order to meet the requirements of urban GIS applications for information query, planning, design, emergency response and society-oriented service, the authors designed and implemented a general-purpose urban GIS placename location tool. Adopting three-layer architecture, this tool consists of a placename database, a management & search engine and an interface toolbox for maintenance and query. With placenames standing for point features or rectangular regions, this placename location tool includes functions such as database setup & maintenance, placename search, quick fuzzy matching and map redirection. A placename database, which is convenient to establish and update, can not only quickly lead a UGIS user to places of interest, but also serves as a presentation of feature classes, and hence provides a data foundation for advanced query or analysis. |
