Remote sensing is an earth science that is critical for infrastructure, oil and gas, heavy construction, forestry, and urban planning.  Remote sensing is also vital in military applications.
It is the acquisition of information from a distance, and involves advanced sensory equipment placed on satellites, drones, aircraft, and on ships.
For two generations, the United States dominated the industry, because it was the US who invested so heavily in GPS and satellite systems, and built the new science around advanced mapping and surveying.  
 
遥感是地球科学的重要组成部分,对于基础设施、石油和天然气、重型建筑、林业和城市规划至关重要。遥感在军事应用中也至关重要。它是从远处获取信息的过程,涉及将先进的传感设备安装在卫星、无人机、飞机和船只上。
在过去的两代人中,美国主导了这一行业,因为正是美国在GPS和卫星系统上进行了大量投资,并围绕先进的制图和测量建立了这一新兴科学。

But beginning ten years ago, Chinese research in the field began to supplant top Western institutions, like NASA, the US Geological Survey, and the top US and European universities.  
It is now China who leads the field, with half of the world's total research, and dominant positions in new patents, research funding, and applied research.  And today, Chinese institutions hold the top six spots in rankings for Remote Sensing.
 
但十年前,中国在该领域的研究开始取代顶尖的西方机构,如NASA、美国地质调查局以及顶级的美国和欧洲大学。如今,中国在该领域处于领先地位,占据了全球研究的一半,并在新专利、研究资金和应用研究方面占据了主导地位。现在,中国机构在遥感领域的排名中占据了前六名。
