Framework: Under the ENAC Incentive Program of Urban Dimension / Exploration in Urban Scaling Project, a series of workshops and lectures toward a scientific view of global urbanization and the built environment.
Abstract: The ongoing global phenomenon of people migrating to cities is referred to as urbanization and primarily manifests itself in the continuous and often rapid spatial expansion of urban agglomerations. Nevertheless, the dimension and structuring behind this process can be considered as a spatial continuum ranging from rural to urban settlements. Accordingly, gathering a detailed global knowledge about the size, form (e.g., compact or spread) and spatial distribution (e.g., dispersed or nucleated) of different types of settlements represents a major issue to better understand urbanization and develop effective mitigation, adaptation and management strategies. The TerraSAR-X add-on for digital elevation measurement (TanDEM-X) is a German Earth observation mission collecting a total of two global coverages of very high resolution (VHR) synthetic aperture radar (SAR) X-band data with a spatial resolution of around three meters in the years 2011 to 2013. With these, the TanDEM-X mission (TDM) provides a unique data set that is highly valuable for the analysis and monitoring of the global human settlements pattern.
This presentation introduces the basic methodology for a fully-operational detection and delineation of built-up areas from VHR SAR data along with a description of the resulting global settlement mask - the Global Urban Footprint (GUF). The GUF shows a high potential with respect to an analysis of urbanization patterns, peri-urbanization, spatio-temporal dynamics of settlement development as well as population estimation, vulnerability assessment and modeling of global change.
Dr. Thomas Esch is leader of the “Urban Areas and Land Management” team at DLR-DFD. He received the Diploma degree in applied physical geography from the University of Trier, Germany, in 2003, and the Ph.D. degree in physical geography and remote sensing from the University of Wuerzburg, Germany, in 2006. Between 2006 and 2008 he was a Scientific Employee at the Department of Remote Sensing, University of Wuerzburg where he was working on urban remote sensing applications. In 2008, he was with DLR-DFD and in 2009 he became leader of the “Urban Areas and Land Management” team. He has vast experience in urban remote sensing, SAR applications, sustainable urban development, land management, biodiversity, energy efficiency and project management. In particular, he has participated in several national and international projects and coordinated the activities for the implementation and development of the Global Urban Footprint. Thomas Esch is also Co-Leader of the GEO task SB-04 "Global Urban Observation and Information and he published more than 25 papers in international peer-review journals and presented more than 75 research works in workshops and conferences.
