Climate change defies cities across the globe with severe challenges. Greenhouse gas emissions from all sectors (energy, transport, buildings, etc.) must be reduced substantially and within a short time period to limit global warming effectively. Simultaneously, urban fabrics must be transformed to adapt to a shifting local climate, extreme weather and cumulating environmental risks. This demands redesigning green, blue and grey infrastructures, and a broad deployment of nature-based solutions ranging from individual buildings to regional landscapes. These complex issues raise novel questions regarding the integrated assessment and planning of possible response policies and measures.

In this context, the use of geomatics, i.e. the collection, distribution, storage, analysis, processing, and presentation of spatial data through computer technologies, has received growing attention. It allows integrating large and heterogeneous data sets, to explore their spatial relations and patterns, and to communicate about interpretations. This offers promising avenues towards a better understanding of the problems and solutions at hand in a given city, but also to novel forms of governance and decision-making, supporting engagement, participation and transparency in a highly complex and uncertain action domain.

Dr. Umamaheshwaran Rajasekar, National Institute of Urban Affairs, India

Dr. Umamaheshwaran Rajasekar is chair of the Urban Resilience Unit and Heading the Climate Centre for Cities (C-Cube) at National Institute of Urban Affairs, India. He has over 17 years of experience in developing risk reduction strategies, climate change analysis, institutional strengthening for governments, INGOs and multi-lateral agencies. His recent efforts have been towards bridging the technology and communication gap to enable informed decision making. He has been the team leader and project manager for some of the pioneering risk resilience efforts in India including implementation of early warning systems, urban disease surveillance and city resilience strategies.

Dr. rer. nat. Hendrik Herold, IOER

Dr. Hendrik Herold is senior scientist in the land-use monitoring research group of the Leibniz Institute of Ecological Urban and Regional Development (IOER) in Dresden, Germany. An expert in spatiotemporal data analysis and modeling, he conducts research in the fields of image analysis using high-performance computing and uncertainty handling in the context of long-term geospatial monitoring and modeling. The fields of applications range from settlement structure detection, ex-post impact assessment, ecosystem services to real-time sensor-based urban monitoring. Before launching his academic career, he studied geography, geology and meteorology with a special focus on geoinformatics, including a period of study at Ohio State University in Columbus (USA). In 2015 he was awarded a doctoral degree in geoinformatics by the TU Dresden, Germany.

Prof. Sanjay Ghosh, IIT Roorkee

Dr. Sanjay Ghosh is a professor at IIT Roorkee, specialised in geomatics engineering. He did his undergraduate and graduate studies at the Univeristy of Roorkee, now IIT Roorkee and received a Ph.D. from University of Strathclyde, Glasgow in 1991 with Prof. George Flemingunder Commonwealth Scholarship, United Kingdom. His present research domains are biodiversity, watershed and water security, river morphology, agriculture crop identification, urban change assessment and climatic changes and developing remote sensing algorithms for machine learning and deep learning. Presently, he is the head of Civil Engineering Department, established in 1847, at Indian Institute of Technology, Roorkee. He serves on various national committees related to Smart Cities, Spatial Data Initiative of Resource. He published 97 journal articles and guided 23 Ph.D. and 73 Master’s theses.

Dr.-Ing. Robert Hecht,  IOER

Dr. Robert Hecht is a senior scientist at the IOER with expertise in the fields of geoinformatics, cartography and applied remote sensing. He received his PhD degree from the Faculty of Environmental Sciences, Dresden University of Technology Dresden on developing approaches for automatic building classification and urban structure type recognition. His current research focuses on spatiotemporal analysis, monitoring and geovisualization of settlements and open spaces, which also includes vegetation mapping, building stock analysis, and population mapping. His general interests include geospatial pattern recognition, machine learning/AI and big data applications, quality aspects of spatial data, VGI and crowdsourcing, and developing location-based services in an urban context.


Prof. Dr. Marc Wolfram, Director, IOER

Prof. Dr. Marc Wolfram is the Director of the IOER and full professor of spatial development and transformation at Technische Universität Dresden. He has an interdisciplinary academic background and extensive experience as a consultant and senior investigator in Europe (2002-2012), doing collaborative research on diverse urban sustainability issues together with stakeholders at all levels. He also worked as an associate professor in South Korea (2013-2019), pioneering research on transformative urban change dynamics, and advising global city networks, UN bodies and funding agencies. His work has been published widely in leading journals.
