| Abstract | The recent floods in Thailand have caused damage to people and the economy. The government will have remedial measures to help victims in various areas by surveying the number of impacts that occur to the victims. However, this process will create gaps between flood impact surveying. Therefore, the researcher developed flood areas assessment using open data and open-source software to assess flooded areas from Sentinel-1A data compared with flood data from the Geo-Informatics and Space Technology Development Agency (GISTDA). And analyze the number of people affected by flooding in the area. As a result, it was found that the affected area of flooding was 387,471.56 rai. While the error value from the flooded area of the GISTDA was 6.83%, the accuracy was 93.17%, and the affected population of the sample area was 69,644. These results complement the disaster-affected area (flood) announcement but can specify the extent of the quantitative and spatial flooding. It can be used as crucial information for declaring disaster-affected areas (floods), considering payment of compensation, and planning to manage floods to be more effective in the future. |
