In this talk, the presenter introduces a European initiative with global effects that aims to support the uptake of Earth Observation (EO) data products and services by increasing European capability to generate timely, accurate, disaggregated, people-centred, accessible and user-friendly environmental information based on EO data. The initiative - Open Earth Monitor Cyberinfrastructure - is following a well defined workflow: (1) Identify gaps and needs analysis : finding out what are the bottlenecks of data platforms together with stakeholders; (2) Use open source EO computing engine : integrating EO with in-situ data to obtain improved geospatial data services and products; (3) Build better data portals: harmonise, bridge and improve existing open source platforms; Make data platforms FAIR: improve accessibility of data with open source licences and capacity building; (4) Serve concrete goals: all Open Earth Monitor activities are centred around pre-defined use cases with various stakeholders.
