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!
As a follow-up to the two preceding advisory support missions to the Dominican Republic, in 2010 and 2011, UN-SPIDER conducted an Institutional Strengthening Mission and organized a one-week training course to strengthen the remote sensing capacities of the inter-institutional Geo-Spatial Information Team for Risk Management to derive flood-related information from satellite imagery. The training course was organized with the National Emergency Commission and three regional support offices: IGAC, CATHALAC and CONAE and took place from 13 to 17 May 2013.

The training that was part of the Institutional Strengthening Mission included lectures and hands-on sessions which were provided by experts from CATHALAC, IGAC and UN-SPIDER. Topics included: introduction to remote sensing for disaster risk management and emergency response; acquisition of satellite data and useful data products for flooding; pre-processing and supervised and unsupervised classification of multispectral images; calculation of indices and change detection with multispectral images; introduction to radar data; use of digital elevation models for hydrologic modelling; use of thermal data for change detection; and introduction to the web portal.
