Query Planet Webinars - AI for EO at scale

Webinars dedicated to Query Planet, an ESA-funded project supported by PhiLab that aims to facilitate the use of Artificial Intelligence (AI) algorithms to build large-scale Earth Observation applications exploiting Sentinel-2 and commercial data sources. The goal of the project is to create and open-source AI solutions that tackle state-of-the-art and compelling EO challenges. These use-cases build on the Sentinel Hub service and the open-source eo-learn library.

Query Planet: AI for EO at scale - Introduction

The first webinar was held on March 24^th 2022. We provided you with an overview of the use-cases developed, namely super-resolution technology for optical sensors, forest and tree species mapping of Europe, and efficient object detection at scale. For each use-case we outlined technical details and the created open-sourced material, e.g. data, code, models, which will be described more in detail in the second hands-on webinar mentioned above. Knowledge of machine learning and deep learning will help the understanding of the algorithms, although this is not a prerequisite. General agenda:

• Project motivation and aim
• Super-resolution of Sentinel-2 time-series imagery
• Pan-European forest and tree species mapping using Sentinel-2 imagery
• Efficient object detection using multi-scale satellite imagery
• Open-sourcing the use-cases

Ask the Sentinel Hub Team

The Sentinel Hub webinar - Ask the Sentinel Hub Team - was held on October 28, 2021. To learn more about Earth Observation and Sentinel Hub tailored to your needs, this session had a slightly different format. Prior to the event, you were invited to watch a Short Course on Earth Observation Methods and Data and send us questions on various topics from EO and Sentinel Hub. During the live session, we first answered the questions received and then opened the opportunity to discuss other topics related to Sentinel Hub and remote sensing. This session was suitable for those just entering the world of remote sensing as well as those who wanted to deepen their knowledge.
