Description

The present invention relates to a satellite data analysis device and a satellite data analysis method using multiple data sources. More specifically, the present invention utilizes satellite data such as satellite images and GPS data to provide satellite data capable of analyzing movements of people, changes in movable property, and changes in real estate for any target area in the world. It relates to an analysis device and a satellite data analysis method.

Traditionally, companies have used internal and external data sources to conduct research and monitoring operations. The types of data sources used include in-house data sources such as business data and customer data accumulated in-house, and external data sources such as data obtained from mobile phone network base stations (Patent Document 1) and satellite data. It has been known.

Analytical work on these data has been labor-intensively performed by specific departments within the company, or has been performed by commissioning external research companies or consulting companies. If a company conducts data analysis in-house, it must continue to secure human resources with highly specialized skills in-house. did not become. Due to these restrictions, companies have had no choice but to conduct surveys with limited conditions such as survey targets, regions, and periods.
