A web map to track COVID-19 data with d3.js. Many dashboards are still using web-Mercator for global map and choropleth for absolute values; this is wrong so we thought we cartographers should stand up! With Yue Lin, Armita Kar, and Ningchuan Xiao.

Delay is a primary indicator of transit and we used GTFS to measure that. It changed, a lot.

Teaching, Ohio State University, Department of Geography, 2021
This course introduces principles of geographic information systems (GIS) and their applications in spatial analysis and information management. The course is designed to give students an understanding of cutting-edge geospatial technologies, their capabilities, uses, and limitations. Representative applications for each discipline area are demonstrated in the computer laboratory portion. (placeholder, will update later)
Workshop, University Consortium for Geographic Information Science, 2021
The ability to visualize large amounts of information in real time on interactive maps has never been more important for GI scientists and specialists. Web-based and open-source platforms, such as the mapping library leaflet and the noSQL database MongoDB, are becoming more popular and useful for their real-time functionality. This workshop will serve as an introductory technical training on full-stack geo-visualization. The workshop will include an overview of web-based platforms, mapping libraries, and the backend infrastructure. During this interactive and hands-on session, all participants will have a chance to build a small web map project with a provided data pack. The whole process of programming and debugging will be demonstrated. There will be time for both development and answering questions that participants may have.
