中文摘要：
火星空间数据量正在前所未有的增长，我国也将在2020年拥有自主的火星探测数据。为改变火星数据研究和应用依赖计算机自身配置的现状，提升数据可视化、共享与应用的效率，研究了面向服务的火星空间信息可视化技术。针对火星数据特性，研究了火星坐标系和火星数据投影支持及网络覆盖服务（WCS）缓存支持等问题；搭建了数据可视化原型系统．系统支持火星坐标系；设计实验证明了调用缓存服务且存在缓存瓦片时，系统实时调度数据的响应效率相比没有时提升了10倍以上。与其他空间信息系统进行对比，系统对火星数据的可视化问题有更强针对性。
英文摘要：
The amount of Mars spaee data is growing at an unprecedented rate, and our country is going to have independent Mars exploration data in 2020. In order to change the situation that Mars data research is highly dependent on computer configuration and improve the efficiency of data visualization, sharing and application, a service-oriented Mars space information visualization technology is proposed in this paper. Based on the features of Mars data, several problems are studied, including the Mars coordinate system, Mars data projection support, Web Coverage Service （WCS） cache support, etc. A Mars data visualization prototype system supporting Mars coordinate system is constructed. An experiment is designed and proved that the response efficieney of real-time scheduling is improved by 10 times after using the caching service and caching tiles. Compared with other space information system, the system is more fit to visualize Mars data.
