Students won Poster Competition

March 3rd, 2016 | Comments Off on Students won Poster Competition

A research poster, entitled “An Interactive Web-based 3D GIS Platform for Estimating Urban Solar Energy Potential” and prepared by Wei Huang, Shahram Sattar, Annie Chow and Shishuo Xu, won the 4th place in the 2016 Graduate Student Poster Session held during the Association of Ontario Land Surveyors (AOLS) 124th Annual General Meeting, 24-26 February 2016 in London, Canada.


The research is part of a 3DSolar project funded by Onatrio Centres of Excellence (OCE), Connect Canada and Woodstock Hydro, to develop an innovative web-based 3D environment for modeling and precisely estimating solar energy potential on urban rooftops. Using 3DSolar, users can explore 3D model of their rooftops, play and place the selected solar panels, and get instant estimation of the output of electricity generation, with other simulation results such as environment footprints (CO2 savings, equivalent tree saved, etc.).

Wei Huang, Shahram Sattar and Shishuo Xu attended the exhibition of FutureOxford Expo 2016, held in Oxford County on 28 January 28 2016, to showcase the 3DSolar tool developed under an OCE-funded project. The 2016 Future Oxford Expo was announced by Future Oxford Transition Board on October 28, 2015 following the endorsement of the Future Oxford Community Sustainability Plan by all nine municipal Councils. The event was “a showcase of Oxford’s successes and leadership in environmental action, building a vibrant economy, and the pursuit of health and well being for all citizens”.

Wei Huang won 1st prize of Doctoral Student Paper Competition

March 15th, 2015 | Comments Off on Wei Huang won 1st prize of Doctoral Student Paper Competition

PhD candidate, Wei Huang, won the first prize of Doctoral Student Paper Competition organized by the International Conference on Location-based Social Media Data held in Athens, Georgia, USA, March 13-14, 2015. The conference aims to bring along researchers from multidisciplinary fields and perspectives to share ideas and findings of research related to social media data and bid data analysis.


Existing researches in human mobility usually model the spatial-temporal movement without considering the change of human activities. Wei’s paper, entitled “Improved prediction of human mobility by detecting activity changes”, presents a new method to analyze massive human trajectories by first looking any possible activity changes before performing prediction. His method shows a significant improvement in terms of predicting accuracy of human movements, with an experiment conducted on a 5-year GPS trajectory data provided by the Microsoft GeoLife. The outcome of his research fills the current void of urban science/engineering with a wide range of applications in emergency response, intelligent transportation systems, and urban planning. Wei is currently working toward mining the spatial-temporal data provided by Twitter and explore the semantic information from the Twits for measuring the similarity of human activities.
