Introductory Advanced Techniques: CRST
In this section, the main aim is at providing readers with brief concepts of CRST (Computational Remote Sensing Technology), its history of generation and development.
In reality, traditionally understanding remote sensing technology (RST) has a lot of misunderstanding. In general, because the remotely sensed substances are lying on the surface of the Earth, naturally, people classified RST into the discipline of geography initially. That lead to that many geographical professionals as main participants in the world have been investigating the remotely sensed substances. Owing to a fact that most of them failed to understand what is RST indeed because of a big disciplinary gap. Physically speaking, the scale of their researches is limited and confined to superficial level of the remotely sensed substances. In fact, in the study of RST, the most important substance is photon which has established a lot of correlation. If ones fail to know physical and physicochemical properties of photon being employed by quantum theories, actually they do not completely understand the nature of RST and fully utilize RST.
Nevertheless, if ones know it and interrelation with other technology, they are able to develop it at a high technical level and dig into very deep level from macro to micro in a sense of the remotely sensed substances. Namely, the investigating the remotely sensed substances and natural phenomena by means of RST is remained at the scale of microstructure (atomic, molecular level) and transport phenomena (heat, momentum and mass transport).
The CRST was developed on the basis of such a fact by means of the extracted data being seamlessly transferred into diverse relevant fields, and then implement many different relevant tasks by means of scientific calculation (i.e. modelling) in the field of science and engineering. it has achieved a great. Nevertheless, it is still being actively developed with a great practical significance.
