The Dartmouth Flood Observatory, based in the United States, uses remote sensing data to detect, measure and map river discharge and flooding. It publishes rapid response inundation maps during a flood as well as an atlas of large floods from 1985 to present.

Data from the observatory are used by several disaster alert and relief agencies, including Sentinel Asia, Thomson Reuters AlertNet, the UN Office for the Coordination of Humanitarian Affairs and Europe's Global Disaster Alert and Coordination System.

MODIS is a key instrument aboard NASA's Terra and Aqua satellites that is often used in disaster management for mapping anything from vegetation to floods or fires. It collects data in 36 spectral bands, twice a day.

The MODIS website publishes technical specifications of the instrument, provides access to data, processed products andf maps. It also hosts a large collection of MODIS images from across the world.

AARSE is a nongovernmental network of African scientists and professionals working in remote sensing and geographic information systems. It holds a biannual conference and runs regional and local seminars and workshops on how to use remote sensing for environmental studies.

The AARSE website publishes contact details of council members, news about developments in remote sensing that are relevant to Africa and a list of events among other information.

UNEDRA promotes collaboration among African universities in disaster risk reduction using remote sensing and geoinformation.

It publishes online training courses, runs regional workshops and provides advice on curricula development, among other activities. Information on its activities and achievements is made available through the UNEDRA website together with a list of participating universities and contact information for organisations wishing to join the network.
