This paper is the first of a series that describes some of the main dataset resources presently shared through the GEOSS Platform. The GEOSS Platform has been created to provide the technological tool to implement the Global Earth Observation System of Systems (GEOSS); it is a brokering infrastructure that presently brokers more than 190 autonomous data catalogs and information systems. The paper analyses the China Satellite datasets and describes the data publishing process from China GEOSS Data Provider to the GEOSS Platform considering both administrative registration as well as the technical registration. The China Satellite datasets are considered as one of the most important satellite data shared by the GEOSS Platform. The analysis provides some insights as well about GEOSS user searches for China Satellite datasets.

This report aims to support the work of the JRC.B6 (Digital Economy Unit), which provides scientific and technical services to the DG RTD for improving and evolving the GEOSS (Global Earth Observation System of Systems) Platform. In the framework of this Administrative Agreement (called EOVALUE), a specific task deals with the analysis of the GEOSS users and data content. The GEOSS platform is a global hub for Earth Observation (EO) data, representing an overarching infrastructure with the main task of easing discovery and access of data made available by different national and international organizations by means of heterogeneous publication systems. GEOSS is managed and realized under the coordination of the Group on Earth Observations (GEO), an intergovernmental initiative comprising more than 100 national governments and in excess of 100 Participating Organizations aiming to benefit different societal benefit areas by means of Earth Observations. In 2017, an analysis of GEOSS data content and its users was done by JRC.B6. The present work aims to update such an analysis, in a consistent way, and understand the main changes occurred in the last few years., This is the accepted version of EOValue Deliverable 1.1 version 2. The published version is available on the EOValue JRC Science Hub Community. EOValue is a three-year project (2018-20) funded by the H2020 research programme and implemented by the European Commission Joint Research Centre
