UN-SPIDER Knowledge Portal
Help Shape the Future of the UN-SPIDER Knowledge Portal
The UN-SPIDER Knowledge Portal is your one-stop platform for resources on space-based disaster risk management. It provides: • Links and guidance on satellite data sources and applications • Recommended practices and step-by-step methodologies • Training materials and tutorials • Case studies and user stories from real-world applications • News and updates on UN-SPIDER activities, events, and global developments
Since its last major review in 2012, the Portal has evolved significantly. Now, we want to hear from you.
We invite you to take part in the 2025 evaluation of the UN-SPIDER Knowledge Portal!
The International Symposion on Remote Sensing of Environment is convened biennially by the International Centre on Remote Sensing of Environment (ICRSE) and the International Committee on Remote Sensing of the Environment (ICORSE), a standing committee of the International Society of Photogrammetry and Remote Sensing (ISPRS). The 2015 edition of the Symposium took place in Berlin, Germany, in 2015.
The 2017 symposium is hosted by the South African National Space Agency (SANSA) and coincides with the adoption of the African Space Policy and Strategy by the African Union Heads of State and Government in January 2016. The programme includes sessions on topics such as "Disaster Resilience and Geohazards" and "Data and Information Systems and Spatial Data Infrastructure".
