為了加快數(shù)字城市的建設，提出一種基于GIS 和領域本體的城市網(wǎng)格坐標數(shù)碼地圖
的設計方案。地理信息系統(tǒng)以其強大的查詢、分析、管理和調(diào)用功能，在本文的城市網(wǎng)格坐標數(shù)碼地圖中得到了充分應用。領域本體采用UML 和面向?qū)ο蠹夹g進行表示，可克服專用本體描述語言和表示方法的不足。同時采用蟻群優(yōu)化方法來解決城市網(wǎng)格坐標數(shù)碼地圖中的最短路問題。該地圖以地理信息名片作為數(shù)據(jù)采集的服務前端，以語音、短信息、廣播和網(wǎng)站作為互動的平臺，為城市地理信息服務大眾提供新的服務模式。

Abstract: In order to quicken the construction of digital city, it proposes a design of City
Grid-Coordinate Digital Map (CGCDM) based on Geographic Information System (GIS) and
domain ontology. With the development of science technology, Geographic Information System (GIS) has gained many applications in fire succor for its strong inquire, analysis, management, transfer functions. Domain ontology applies the UML and object-oriented technology to represent some important concepts, which can overcome some shortcomings with knowledge engineering specific methods and languages. Also, it applied the Ant Colony Optimization (ACO) to implement the shortest path decision. On the service stage of geographical information card and interactive platform of sound, note, network and broadcast, CGCDM help government manage conveniently, digitally house numbers in city, and it also decreases government’s economic burdens.
