GRID-Arendal is a centre collaborating with the United Nations Environment Programme (UNEP), located in Arendal, Norway. The centre was established in 1989 by the Norwegian Government as a non-profit foundation to support the United Nations in the field of environmental information management and assessment, capacity-building and communications and outreach. It is part of the GRID network of environmental data and information centers, under the UNEP Division of early warning and assessment. The GRID program itself was established in 1985 as a part of Earthwatch with the goal of providing useful environmental data to researchers and policy makers. GRID centers also support developing countries through training programs and transfer of technology pertinent to geographic information systems and remote sensing.
GRID-Arendal works to synthesise environmental data into information products accessible to the non-expert in developing-world countries. The GRID-Arendal website hosts a collection of marine photographs and maps, including topographic maps of many countries by region.
