Satellite Data as Big Data
Satellite data is expected to be useful because it can obtain ground data over a wide area and in a homogeneous manner. Since it can also acquire data in the infrared and microwave regions of non-visible light, which are invisible to the human eye, it is being studied for a wide range of applications. At the same time, however, satellite data is limited in resolution (image resolution), and with various types of sensors available, it is difficult for end users to directly utilize the data, so there is a need for players who can provide appropriate data.
The history of satellite data is long, starting with the purpose of military use, and has long been utilized for research purposes. Until now, features and changes have been captured visually by analyzing the combination of wavelengths in each sensor or by coloring satellite images according to the analysis results. Many satellites orbit the same location regularly and are capable of capturing time-series changes, so they are so-called "big data," and analysis methods have had limitations up to now.
