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.
