Big spatial and spatial-temporal data have been, and continue to be, collected with global positioning systems, mobile devices, citizen participation, high-resolution remote sensing, census surveys, and volunteered geographic information. The research in our lab focus on big data analytics and visualization through the development of new theory, methodology, tools, and applications to analyze big and complex spatial data, acquire new knowledge, design problem-solving solutions, and support decision/policy making. We are conducting research and working on projects in the following closely related areas (for each you may find related publications and software on this site or in my CV):

  • Developing new computational, visual analytical, and statistical methods to process, analyze, and understand big geospatial and temporal data;
  • Addressing science and engineering problems concerning the environment, society, and humanities such as climate, health, security, transportation, urban planning and environment engineering.

To Prospective Graduate Students: We are always looking for talented graduate students. The Department of Geography at University of South Carolina is among the strongest geography programs in the U.S. (top 10 in the NRC survey), where you can work with world-renowned scholars. Please follow the procedure to apply.

  • You are invited to participate in a usability test for flow mapping, where you will be presented a series of flow maps and answer a number of questions. 
  • With the iRedistrict redistricting software, you can design professional and high-quality redistricting plans easily. iRedidstrict Online will be released soon.

AAG 2015 CFP: Spatial Data Mining and Big Data Analytics

Big and dynamic spatial data have been, and continue to be, collected with modern data acquisition techniques such as global positioning systems (GPS), high-resolution remote sensing, census surveys, and internet-based volunteered geographic information.
