The objective of this investigation was to provide PIKSEL with EO data sources. Several steps were followed to achieve this goal. The initial phase of the research involved the identification and compilation of EO data sources available. The selection process aimed to encompass a wide range of geospatial, environmental, and climatic data to cater to the diverse needs of the PIKSEL use cases and its users. Subsequently, the EO data available was subjected to an evaluation to determine its relevance to the specific application and objectives of the PIKSEL platform. This assessment considered factors such as data accuracy, spatial and temporal resolution and data format. Once the relevant EO data sources were identified, the next step involved a detailed analysis of the data downloading procedures associated with each source. Each provider often presents unique requirements, access protocols, and data delivery formats, necessitating a thorough understanding of the technical intricacies and obtaining the necessary credentials for data acquisition. To streamline and automate the data retrieval process, a custom Python script was developed for the specific case of the evolution of the coastline. Recognizing the importance of user experience, a user-friendly interface was designed to facilitate straightforward data management. The interface aims to simplify the process of accessing and querying, ensuring that users, irrespective of their technical expertise, can efficiently interact with the platform's resources. However, various hurdles were encountered during the project, including diverse data access procedures, lack of standardization among data channels, and challenges in obtaining and understanding Copernicus data. Despite these challenges, this work presents a valuable resource for non-programming experts seeking to manage EO data with ease. The work also explores future opportunities to expand the platform, integrate other Copernicus services, include diverse relevant sources, and implement the user interface on the PIKSEL website.
