遥感科学数据应用态势分析

遥感数据是影响遥感科学研究方法、实验思路、解决方案的重要因素之一。以探索面向遥感科学数据的学科情报分析框架为目标，以《Remote Sensing of Environment》期刊1999~2018年发表的学术论文为例，利用文献计量和知识图谱分析方法，展现遥感科学数据的利用情况。结果表明:满足特定专业领域需求的遥感科学数据日益丰富，光学遥感、微波遥感和激光雷达数据的应用结构已发生明显变化，从20世纪90年代的8∶1∶1发展为5∶3∶2,多角度观测、机载观测平台等新型观测方式展现出独特的优势。遥感科学数据和相关研究分析方法的发展和完善，不断推动对复杂地理生态过程以及人类活动对环境影响的系统化、综合性理解。

Application Analysis of Remote Sensing Data based onRemote Sensing of Environment

Remote sensing data is one of main factors affecting remote sensing research methods, experimental design and solutions, etc. In this study, the articles published on the JournalRemote Sensing of Environment during 1999~2018 were collected to quantitatively analyze the utilization situation of remote sensing data and research hotspots using bibliometrics and knowledge graph methods. The results showed that more and more specific professional sensors, remote sensing data, derived data emerged rapidly. Meanwhile, microwave remote sensing and LiDAR were burgeoning, and the structure of application of optical, microwave and LiDAR remote sensing data had changed significantly, from 8∶1∶1 to 5∶3∶2 during the past decades, multi-angle and airborne observation platform get favors of scientists. The improvement of remote sensing data and analytical methods were continuously promoting a systematic and comprehensive understanding of complex geo-ecological processes and impact of human activities on environment.
