UCGIS Workshop: Full-stack Geo-visualization 101: How to Make Productive Webmaps

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.
