Abstract: With the techniques of remote sensing (RS) applied in the observation of the water pollution from the surface of the earth to space, the research method of normal water quality has got a new point of view beyond routinization, and it indicates that the modern technique should have the importance of the precision improved and enhanced while the process is outspreading. On the other hand, RS can improve the limited conditions of the normal scale span and time efficiency while techniques of RS are applied in observation of the water quality, it also exists a large potential technical space to be improved for the water pollution information collected from RS and image translation at the present stage, not only for hardware techniques but also for software techniques, and RS can not fill entirely in status of the normal surface water pollution monitoring because of the error based on grade analysis of the practicality operation. Many studies about the RS process and image translation indicate that the results from remote sensing should be validated and reinforced by surface complementarities, even for the extrusive water pollution items which appeared in the image strongly, the conditions of the water quality will be investigated fully and accurately. Therefore the authors described the RS presentation and discussed the techniques of RS process. It is important and useful to analyze items applied in water pollution research with impersonal cognition and detail scale range in the application practically.

Key words: water pollution, remote sensing (RS), image translation, spatial span
