Abstract
This document is dedicated to the requirements collection and analysis as well as the Business Process Modeling and Notation in the EO4EU project. In a first step, the document describes the approach and methods used to collect the requirements coming from three distinct sources, namely, the Description of Actions, the use cases established by the project’s consortium and the external users. In a second step, the document summarizes these requirements. This allows designing the platform to meet the needs of a wide range of users and to be single point of access to Earth Observation data and processing tools. The document then proceeds by describing the user journey in using the platform for multiple scenarios using Business Process Modeling and Notation (BPMN) concepts. These BPMNs describe the user and the platform interaction from a high-level perspective.
