A Data-Driven Approach to Place-Based GIS
A place is characterized by its semantics and human conceptualizations instead of just an abstract geometry in space. The emergence of big data brings new opportunities for us to understand the semantics of places and associated human experiences, emotions, movements, and activities.

GeoComputation and Big Data
Geospatial Big Data describes the phenomenon that large volumes of georeferenced data captured by millions of environmental and human sensors in a variety of formats such as remote sensing images, crowdsourced maps, geotagged videos and photos, transportation smart card transactions, mobile phone data, location-based social media content, and GPS trajectories.

Image-based Geo-Localization
When users browse beautiful scenery photos uploaded on a social media website, they may have a passion to know about where those photos are taken so that they could view the similar sceneries when they go to the same spot.

Public Transportation Optimization
Public transportation systems, in particular, bus systems, play an essential role in the process of urbanization. Typically more bus stops enable more people to access the bus whereas lower the efficiency of bus system. We utilize spatial optimization techniques to address this issue.

Place Emotion
State-of-the-art computer vision technologies are utilized to collect, store, handle, manipulate and analyze the human emotion at different places. The research explored what and how people express their emotions at different scales and places, and why and how their emotions would be influenced by environmental factors.
