The report on the Value of Open Data Sharing was first prepared for the GEO-XII Plenary by the GEO Participating Organization CODATA (the ICSU Committee on Data for Science and Technology). Through showcasing diverse benefits of open Earth observations data, the report is designed to facilitate the process of transitioning from restricted data policies to more open policies for government data. 
At the GEO-XII Plenary the report received positive feedback from GEO Member countries and Participating Organizations, who also expressed willingness to contribute supplementary case studies. Therefore, it was decided to maintain this report as a living document, with this version for the record as version 1. The GEO community will provide periodic updates, examples and case studies.
