Chunzhu Wei, PhD researcher at Z_GIS successfully defended her PhD Thesis “Multi-scale spatial analysis methods from neighborhood to megacity”.In her Thesis, Chunzhu focused on applying multi-scale methods to combine different geographical units with physical, social and other contextual characteristics in urban geographic analyses. Chunzhu used in her research project two common geographical units – zoning units and grid-based units in order to investigate the influence of scale in urban geographic analyses from micro-scale to macro-scale. Zoning units were aggregated from census blocks and were mainly used when considering the micro-scale characteristics, while grid-based units were aggregated from remote sensing imagery and were preferred when analyses were carried out at macro-scale.
The results of the dissertation showed that the conceptualized prototypes of zoning-based and grid-based semantic urban forms can serve as “prerequisites” to provide insights into complex human-environment interactions.
Around 30 attendees listened to Chunzhu’s impressive presentation which was followed by a fruitful discussion between the evaluators, Dr. João Porto de Albuquerque from the Centre for Interdisciplinary Methodologies of the University of Warwick and Dr. Dirk Tiede from Z_GIS. Dr. Thomas Blaschke as the main supervisor acted as the chair.
Chunzhu will start her PostDoc career at DLR (Deutsches Zentrum für Luft- und Raumfahrt). She will work on the development of novel evaluation methods and information products based on SAR and multispectral satellite data (Sentinel-1, Sentinel-2, Landsat) within the framework of the BMBF project on environmental processes in the Vietnamese Mekong Delta
We wish her all the best for her future endeavours!
