随着对地观测技术的发展，传感器类型与数量不断增加，为了高效管理传感网中相关的信息与服务资源，便于用户按需、全面和准确地获取并应用这些资源，基于传感网信息模型和服务接口规范，设计并实现了地理空间传感网信息公共服务平台GeoSensor。该平台通过调用和组合传感器注册服务、传感器观测服务、实时制图服务和卫星位置服务等多种服务，实时获取传感器、观测数据和数据产品等信息资源，并在天地图上以图形、文字、表格和视频等方式形象生动地展示这些信息资源。GeoSensor系统实现了对遥感、移动和原位等类型的对地观测传感器及其观测数据等资源的在线搜索、即时获取、网络控制和实时制图，可满足应急处理时对传感器检索、观测数据获取、传感器控制和数据产品生成等功能的需求。

With the development of earth observation technologies, sensor type and quantity increase massively. In order to manage information and service resources related to Earth Observation Sensor Web efficiently, allow users access and apply these resources comprehensively and accurately, based on Sensor Web information model and service interface specifications, this paper designs and implements geospatial sensor web Information Public Service Platform, namely GeoSensor. GeoSensor is based on a service-oriented architecture, calls and combines sensor registration service, sensor observation service, real-time mapping service, satellite location-based service and other services, gets real-time sensor information, sensor observational data, data product and other informa-tion resources and demonstrates these information resources in the Map World with graphics, text, tables, and video vividly. GeoSensor mainly consists of four major functional modules:(i) Sensor Retrieval Module which is mainly used for retrieving motion sensors, in-situ sensors and remote sensors according to the specified filter criteria, such as time, space, subject and other conditions; (ii) Sensor Observational Data Retrieval Module is mainly used according to the specified filter conditions, access to various types of sensor observation data, and show these observational data in Map World in different ways;(iii) Sensor Control Module is mainly used to con-trol in-situ sensors and video sensors, and feedback the result of sensor control based on these changes of the sen-sor observational data or the access method of sensor observational data;And (iv) Thematic Map Service is to use sensor observation data to generate thematic maps, and the data products generated by this service can reflect the overall situation within a specific area. GeoSensor achieves online search, instant access, network control and real-time mapping and other functions for these resources. In the future, a more powerful sensor web information public service platform with semantics will be build, which could be used in smart city.
