中文摘要：
本文首先指出智慧地球是数字地球、物联网和云计算等有机的融合，随后分析了智慧地球的主要特性，并重点阐述了智慧地球时代测绘地理信息学的新使命。作者认为我们已经从绘制地形图为主的小测绘发展成为当今以地理空间信息服务为主的大测绘，现在必须抓住机遇，不失时机地拓展智慧地球时代测绘地理信息学的新使命，将传统测绘提升为能够实时、智能地采集和处理海量空间数据、提供空间信息和知识服务的智慧测绘新阶段。
英文摘要：
This paper first pointed out that Smart Earth is consisted of Digital Earth, Internet of Things （ IOT）, and cloud computing. Next, it analyzed the main features of Smart Earth and focused on the new missions of surveying, mapping and geomatics in the Smart Earth era. The authors believed that we have walked through the so called ＂small surveying and mapping＂ that mainly serves topographic maps, and developed into the so called ＂big surveying and mapping＂, the services of geospatial information. At present, we should seize the opportunity and expand new mission of surveying, mapping and geomatics in the Smart Earth era, and make surveying and mapping upgraded to smart surveying and mapping stage which could facilitate real-time intelligence collecting and processing massive spatial data, in order to provide service of spatial information and knowledge.
