摘　　要：提出在新版"天地图·江苏"中实现"省市县服务一体化"的建设思路,整合省市县地图服务资源。主要从省市县地图服务一体化、服务共享和同步、地图边界融合以及利用缓存技术提高地图服务访问速度等展开研究,在"天地图·江苏"电子地图中已取得应用实效。There are mainly some problems, such as data synchronization, resource sharing, repeated investment in construction funds and decentralization of operation and maintenance. Based on the above problems, the leaders of related units put forward the idea of constructing “integration service in provinces, cities and counties” in the new version of MapWorld Jiangsu, integrating the map service resources of provinces, cities and counties. In this paper, we mainly studied the integration of map service, the service sharing and synchronization, the map boundary fusion and improving access speed of map services by caching technology. This study has been applied in MapWorld Jiangsu electronic map.
