his article reviews and analyzes the needs of Earth observation (EO) services' users, stakeholders, and beneficiaries. It identifies the key elements of the value chain of
the European EO infrastructure and builds a comprehensive knowledgebase of those elements, represented as a
relational database. The entities in the database are users,

needs, services, and products. The database also includes
connections between these entities-such as users to needs
and products to services-via mapping tables. Leveraging
data from the relevant policy and requirement documents
as well as from research project reports, the database contains 63 users, 37 explicit needs, and 95 EO products across
six Copernicus services.
Using information from the database, a quantitative
scoring methodology was developed to analyze and select
