Optical Imagery



Same as common pictures, optical imagery is captured by using visible light which can be perceived by the human eye. Like aerial photograph, imagery which is close to visual image can be obtained. In case of the data observed by sensor which can be observed by many frequency bands other than visible light such as the Global Change Observation Mission – Climate “SHIKISAI” (GCOM-C), imagery which is close to visual image can be obtained by combining data of frequency bands which corresponds to the three primary colors – red, green and blue.

When the ground is observed from space, the image is blue-tinged due to the effect of atmosphere. In case of atmospheric corrected product, we can obtain the color close to the real one. The condition of land surface under the cloud cannot be observed.
