The data observed by earth observation satellites are transmitted to the Earth Observation Center (EOC) and other related facilities, which can receive it with large parabolic antennae. The data are processed and analyzed by computer to make satellite images we usually see.
Data analysis means to process the observation data according to purpose for instantaneous understanding. As typical data analysis work, we introduce the following three types of color composition. Let's look at the feature of coloring in each image. |
Natural Color |

The area with many plants like forests and grass fields is colored in green, which is our image of plant. The area with no plant and residential area are colored in raspberry. |
