The disasters group of GEOSS integrates satellite data with other information to help disaster managers reduce vulnerability, improve early warning and support recovery measures.

The group has set up a coastal zone community of practice, established a global wildland fire early warning system and supports key organisations such as Sentinel Asia.

It publishes information about all its achievements as well as targets and planned activities.

The International Charter on Space and Major Disasters, formally opened in November 2000, provides a mechanism for accessing satellite data to help respond to natural disasters.

If a disaster strikes, authorised users can call a single number and request any and all participating satellites to collect data over the affected area.

The charter's website publishes a list of participating space agencies and organisations as well as information on all disasters that have activated the charter, including high resolution images of the resulting satellite data.

UN-SPIDER promotes universal access to satellite data relevant to disaster management. It publishes information on the latest disasters around the world and coordinates Space Aid, through which countries can request satellites to collect data over affected areas.

The organisation also hosts a library of guides on capacity building, disaster management and space application, among other topics.
