本文提出遥感科学发展至今，需要进一步拓展和深化应用的一点思考。遥感已经无处不在，遥感学者不能停留在对传统的航空和卫星遥感数据的处理和分析，应该把现在无处不在的地面摄像、录音甚至是味觉传感数据以及其他社会经济大数据应用起来。遥感学者走出自己的熟悉领域实现跨学科发展，才能取得更大的科学突破。最后对遥感在实现联合国可持续发展目标中的作用进行展望，以期对年轻学者有一定帮助。

Remote sensing as a science and technology needs further and deeper applications. Remote sensing is already ubiquitous. Remote sensing researchers should not stay within the processing and analysis of traditional aerial and space-borne remotely sensed data, instead, they should take advantage of the emergence of ground video, recording, even smell detectors, as well as socio-economic big data in their studies. Only if remote sensing scholars make a stride outside of their comfort zone and carry out cross-disciplinary studies, will there be greater scientific returns. At the end, I state that remote sensing can make a contribution towards the realization of every Unite Nations sustainable development goals in a hope for it to be of help to young remote sensing scholars.
