    "DA4DTE: Demonstrator Precursor Digital Assistant Inter-face For Digital Twin Earth". It started in October 2022 and will end in March 2024 (duration 18 months). DA4DTE will develop the first digital assistant for satel-lite image archives and demonstrate it in three use cases (ves-sel detection, water bodies dynamics, training dataset con-

    Moreover, the added value of a Digital Assistant capable to understand complex requests related to geospatial data searches could go well beyond the expansion of dimensions that we are able to use to query EO data archives and include also advanced capabilities to understand and process a User request, selecting the most suitable workflow to satisfy the request, being able to autonomously ...

    Demonstrator Precursor Digital Assistant Interface for Digital Twin Earth (DA4DTE) is a project by the European Space Agency (ESA) that aims to simplify the usage of satellite data archives. A BIFOLD research group led by Prof. Dr. Begüm Demir has been pivotal in developing three of the four search engines featured in the digital assistant.

    We present an AI-powered digital assistant that includes four search engines for satellite images (search by image, search by caption, visual question answering and knowledge graph question answering) that are orchestrated by a task interpreter in order to answer complex requests of users looking for Earth observation data. The digital assistant will be demonstrated in three use cases: vessel ...

    The aim was to better leverage the huge amounts of satellite data currently being collected. A key breakthrough was the development of an approach based on querying data archives with images. "Our core competence is in developed machine learning models to analyse large-scale satellite data," explains Demir.

    The German Satellite Data Archive (D-SDA) at the German Aerospace Center (DLR) has been managing largevolume Earth-observation (EO) data in the context of EOmission payload ground segments (PGSs) for more than two decades. Hardware, data management, processing, user access, long-term preservation, and data exploitation expertise are under one roof and interact closely. Upcoming EO-mission PGSs ...

    Systems which provide for the access to satellite data archives along with the data processing and anal-ysis tools have been developed in recent years [2, 3]. Data in such systems can be in geographically distrib-uted archives, while their processing and analysis are controlled by remote users with the use of computing
