AI-DRIVEN CITY DIGITAL TWINS

Get support on choosing a study

The Digital Twin (DT) concept originates from industry and manufacturing. Since there is no commonly accepted definition in the geospatial domain, it refers to a digital replica of the dynamic physical environment. It includes innovations in the Building Information Modelling (BIM) domain, smart cities, or 3D modelling. By adopting Big Data and AI technologies, the city stakeholders can achieve evidence-based planning and decision-making by implementing data-driven processes. The two partners in this collaboration are Big Data for Smart Society Institute (GATE) and the Faculty of Geo-Information Sceince and Earth Observation (ITC). 

Gate City Digital Twins team

GATE is the first Centre of Excellence in Bulgaria to work on integrating and extending scientific excellence and innovation in priority areas such as Big Data and Artificial Intelligence (AI) at regional and European level. It is a purpose-build institute established in 2019 as a joint initiative between Sofia University “St. Kliment Ohridski”, Chalmers University of Technology and Chalmers Industrial Technology, Sweden.

The mission of GATE is to conduct Big Data and AI applied research, to develop innovations and provide education in collaboration with government, industry and entrepreneurs. Based on this, it will generate well educated professionals, new business opportunities and societal impact in Bulgaria and Europe.

GATE provides innovation excellence into four strategic application themes – Future Cities, Intelligent Government, Smart Industry and Digital Health. Value is created in these themes through developing research excellence mainly in topics relevant to the three technology areas – Data Management, Data Analytics and Insight – and on a cross cutting area – Engineering of Big Data and AI systems.

The main contact in the GATE team is Reasearch Leader Dessislava Petrova-Antonova.

Dessislava Petrova-Antonova
Research Leader (Data Management Research Unit)

Dessislava Petrova-Antonova is an associate professor in Software engineering at the Faculty of Mathematics and Informatics and a Research leader of the Data Management Research Unit of GATE Institute, Sofia University. She is a coordinator of the GATE pilot project “City Digital Twin,” where a 3D City Model covering an area of Sofia is under development to facilitate simulation, analysis, and visualization of the urban environment and processes. Her research interests include Data management focusing on data interoperability, semantic enrichment, and domain-specific data models.

Dessislava Petrova-Antonova holds a master’s degree in Computer systems and technologies and a doctoral degree in Communication and computer technology (System programming) from the Technical University of Sofia. She is presently head of the MSc program “Technology entrepreneurship and innovations in IT” at the Faculty of Mathematics and Informatics of Sofia University. She has co-authored more than 80 peer-reviewed academic publications. She has successfully participated in several European and national RTD projects (more than 30).

ITC City Digital Twins team

ITC is the former International Institute for Geo-Information Science and Earth Observation, which now has become a Faculty of the University of Twente. UT-ITC has over 70 years’ experience in training  mid-career professionals and scientists from all over the world in the collection, interpretation, management and visualization of geo-information to support resource management and policy development.

UT-ITC has an extensive track record in undertaking applied research and has a long history in successfully managing more than 1100 consultancy and research projects in over 70 countries since 1958. UT-ITC has abundant expertise in disaster management, spatial hazard risk assessment, flood and landslide hazard studies, developing methodologies for Multi-Hazard Risk Assessment and the design of web-GIS and spatial data portals. UT-ITC has also experience in the organization of training, workshops and study tours in these fields worldwide.

UT-ITC’s mission is to provide international education and conduct high-level academic research to support capacity building and institutional development of professional and academic organizations as well as individuals, specifically in countries that are economically and/or technologically less developed.

The main contact for the ITC team is Associate Professor Mila Koeva.

dr. M.N. Koeva (Mila)
Associate Professor

Mila Koeva is an Associate Professor at University Twente, International Institute of Geo-Information Science and Earth Observation ITC, The Netherlands.

She holds a PhD and MSc. Degree from the University of Architecture, Civil engineering, and Geodesy in Sofia. Her career includes ten years of working as a photogrammetry department of GIS Sofia (www.gis-sofia.bg) producing cadastral and topographic maps and three years of work in a private organization Mapex (www.mapex.bg) leading three EU projects related with geodetic, cadastral and photogrammetric activities.

Her main areas of expertise include Digital Twins/3D modelling, image data acquisition and processing techniques (satellite, aerial, and UAVs), and automatic feature extraction for cadastral mapping and urban planning, among others. More specific, her research focuses is on the implementation of innovative geospatial and machine learning methods based on remotely sensed data in support of 3D urban modelling and cadastral applications.
