A Trial of Urban Area Change Detection by Open Satellite Data Platform

Detection of Changes in the Tokyo Suburbs Using Tellus Simple Analysis

Abstract

This report is an attempt to detect changes such as building construction and demolition in urban areas using data obtained from Tellus, an open satellite data platform. Many methods use data from basic city planning surveys and aerial photographs to capture changes in urban areas. However, these methods cannot capture changes in the height direction. In recent years, with the development of remote sensing technology, satellite data is becoming more open and freer. In Japan, a satellite data platform called Tellus was developed as part of the Ministry of Economy, Trade and Industry's project to make remote sensing satellite data open and free and to promote data utilization, allowing even non-remote sensing experts to use satellite data. It is becoming possible. In this study, we will verify whether it is possible to capture changes in urban areas, such as renewal of buildings, location and withdrawal of residences and commercial facilities, using Tellus data.
