Introduction to Copernicus & openEO

Gain a practical introduction to Copernicus, Europe’s flagship Earth observation programme. Learn how to access and process satellite data through the Copernicus Data Space Ecosystem (CDSE) and openEO platforms. The session will walk you through using the online environment, exploring available datasets, managing data storage, and performing cloud-based analysis — helping you get started with Copernicus tools for research, innovation, or application development.

Thursday April 16
17:00 – 18:00 CET

Accessing Copernicus Data Space Ecosystem datasets via the Sentinel Hub APIs

This session will guide participants through practical ways to access and use datasets from the Copernicus Data Space Ecosystem with the help of Sentinel Hub APIs. You will learn how to connect to Copernicus datasets, integrate them into your own workflows, and make use of advanced functionalities such as on-the-fly processing and visualisation. The webinar is designed for developers, researchers, and innovators who want to streamline Earth observation data access and unlock the full potential of Copernicus for their applications.

Tue, 14 April - 16:00 CET (17:00 EET)

Water Challenges in Bulgaria and Pathways for their Solutions using Earth Observation and AI

Join Mariana Damova, CEO of Mozaika, to discuss urgent water challenges sourced from real-world use cases in Bulgaria that are also relevant across Europe. We will demonstrate how Earth Observation data can provide critical insights and address these issues effectively. To illustrate this, we’ll showcase various applications and introduce ISME-HYDRO®, Mozaika’s operational system for water intelligence based on Earth Observation data and AI.

Building a New Solution for Avalanche Prediction Using Satellite Data and Winning the 10th CASSINI Hackathon EU Space for Consumer Experience

This webinar presents the development of AvMap, a satellite-based avalanche prediction system, and shares key lessons from winning the 10th CASSINI Hackathon. It outlines when a problem genuinely requires a space-based solution, focusing on global coverage, scalability, and continuous data availability. A central insight is that space technologies must connect to broader, non-space markets to achieve real impact and commercial viability. Initiatives like CASSINI provide leverage through access to networks, validation, and visibility. It demonstrates how small, focused teams can transform satellite data into operational services when they prioritize problem selection and execution. Presented by Michael Caneff, CEO of AvMap.
