Develop disaster response and development applications and advocate the use of GIS&RS as a tool. Post Disaster Impact Assessments - High resolution imagery captured soon after a disaster remains an important source of information. - UNOSAT and Sentinel Asia both provide opportunities to acquire this imagery however, the analysis of the data is often carried out by their respective partners. In 2011, SOPAC submitted a request to be a data analysis node for Sentinel Asia and have also had discussions with UN-SPIDER on the same. This will provide more effective support to countries. Application of RADARSAT for mapping flood impacts and its potential use for rapid impact assessment. Methodology developed to use RADARSAT imagery to map flood affected areas Process outlined that will ensure imagery is delivered within 6 hours of the request. However, funding is required to acquire this imagery. Disaster risk assessments require high resolution topography. LiDAR is very expensive and alternative tools such as RTK GPS units provide the same accuracies but not effective for large areas.
