The Asia pacific countries are facing many impacts due to the natural disasters such as earthquake, tsunami, volcano eruption, landslide, flooding, forest fire etc. These will lead to the global environmental change if they are not instantly monitored and managed. The rapid mapping technology has a good potential to overcome these problems, one of which is by improving the resilience of environment to disaster and environmental changes. Remote Sensing (RS) and Geographic Information System (GIS) are powerful technologies for rapidly collecting, combining, analyzing and visualizing necessary information on the damages of the prone areas (Balsatvia, 2013). Therefore, integrating these technologies into a rapid mapping technique is practical for decision makers and end-users in the high-risk developing countries, such as the majority of ASEAN countries. These need to be acknowledged and practiced by young scientists of the high-risk countries, in which they will assist to disseminate the technology to any of the environmental stakeholders. In response to that, a summer school will be held in accordance with the International conference of Indonesian Society for Remote sensing (ISRS) 2016 to assist the young scientists in improving their knowledge in the implementation of the rapid mapping technique for providing fast and accurate geospatial information in the decision-making processes.
