Open Data Sharing for Earth Observations: The Global Earth Observation System of Systems (GEOSS)

Data discover-ability, accessibility, and integration are frequent barriers for scientists and a major obstacle for favorable results on environmental research. To tackle this issue, one that is raised in our book and in this blog, the Group on Earth Observations (GEO) is leading the development of the Global Earth Observation System of Systems (GEOSS), a voluntary effort that connects Earth Observation resources world-wide, acting as a gateway between producers and users of environmental data.

Barbara Ryan, Director, GEO Secretariat, says that, “The primary goal is the assurance of Earth observations so that we can address society’s environmental problems. While many of our activities are targeted toward monitoring global change, we’re actually more concerned about the assurance, continuity, sustainability and interoperability of observing systems, so that monitoring across multiple domains can be done. Governments, research organizations and others actually do the monitoring. We just want to make sure that the assets are in place, and that the data from these monitoring efforts is shared broadly. One of GEO’s primary objectives is to advocate broad, open data sharing, particularly if the data was collected at taxpayer expense—the citizens of the world should have access to that information”

“In this regard, during the first part of GEO, 2004-2009, we looked at the GEO mission as a massive cataloging effort. Then, about two years ago, we changed strategies. We transitioned to a brokering approach whereby interoperability agreements were established with institutions that have datasets and/or databases, rather than us seeking out individual datasets. An example of this approach is illustrated with our agreement with the World Meteorological Organization (WMO). WMO
members have generally registered their data in the WMO Information System (WIS). So we worked on an interoperability arrangement between GEOSS and the WIS resulting in data from one system being discovered by the other system. We are now hearing, particularly from some members in the developing world, that they are getting access to information that they didn’t know existed.”

“WMO members are getting biodiversity and ecosystem information that wouldn’t normally be delivered through the WIS that focuses on weather, climate and water, and GEO members are gaining increased visibility to information in the WIS. It’s a win-win story, and we’d like to have interoperability brokering agreements with any institution that wants its environmental information broadly viewed and accessible throughout the world.”

“Many of the 25 countries that produce 80% of the world’s crops have global forecasting capabilities. GEO is advocating that information from these countries be shared more broadly and openly, and that algorithms be harmonized so that forecasts are improved around the world. Global transparency will help create more stability and a more food-secure world.  A related aspect of the security issue is that governments do not want another government having easy access to what is happening over their domain with the fear that this information will be used against them. While this concern is recognized, most of the information that GEO is interested in transcends national boundaries. Atmospheric, oceanic and many terrestrial processes do not respect national boundaries, and actions in one part of the world often have wide-spread consequences. The benefits of broader data sharing almost always outweigh the risks associated with not sharing data.”

These are welcome words to us here as authors of Spatial Reserves and also most likely will be welcome words for the entire geospatial community. I look forward someday soon to be able to search for and use data using the GEOSS.
