Abstract

In developing countries such as Southeast Asia, there are many areas where urbanization is progressing. In developing countries, detailed data on land use and other matters are often insufficient, making it difficult to understand the status of urbanization, the effects of projects, and the extent of their impact. First, in order to evaluate the effectiveness and accuracy of the urban area extraction method targeting Tokyo and its surrounding areas, we considered land cover classification processing using clustering using optical observation information from Landsat satellites and polarization information from Sentinel. did. The results showed that the accuracy of urban area extraction was improved by using optical satellites and SAR satellites in combination. Subsequently, this method was applied to areas with social infrastructure development in developing countries in Southeast Asia, and the state of urbanization was investigated in detail, and characteristics such as the state of urbanization and the scope of influence associated with social infrastructure development were effectively evaluated.
