The students who took my GIS courses or under my supervision won two Champions for both individual group projects from ESRI Young Scholars Award 2022. Big congratulations and I'm so proud of them! #gis #geospatialdatascience #spatialanalysis

Our paper on measuring building height via single street view images came out! Although my proposal on this work was rejected twice, we didn't stop the endeavor trusting that it's meaningful and has implications for constructing smart cities. authors.elsevier.com/a/1fc963I9x1j9… Smart City

We propose a probabilistic framework based on the gradient descent algorithm for multiobjective optimization. It shows the framework can generate better and faster land use plans than the traditional algorithms (e.g. GA). tandfonline.com/doi/abs/10.108…

Take a look at our article: nature.com/articles/s4146…. It presents spatiotemporal scaling laws for urban pulse, focusing on population fluctuations within a city. These scaling laws require spatial and temporal dimensions to emerge. Mike Batty Chris Zhou Ryan Qi Wang🏳️‍⚧️🏳️‍🌈✊🏿

Daily population fluctuations in cities are not random. HKU Geography Bo Huang, Xingye Tan and Peng Gong uncover universal spatiotemporal scaling laws governing daily population flows in cities. Read the full paper in Nature Communications doi.org/10.1038/s41467…
