Dr. Yan Li, Slippery Rock University Visiting Lecturer, was the guest speaker at a colloquium hosted by the Mathematics and Computer Science Department on March 1, 2011, in Phillips Lecture Hall. Her topic was "The Applications of SVG to WebGIS."
Dr. Li is a visiting professor from South China Normal University, Guangzhou, China, where she is researching new techniques in spatial and spatiotemporal data analysis and geographic information systems. She has authored nearly 100 publications on spatial analysis, RS image processing, spatial data infrastructures, spatial data sharing and integration, and the applications of geo information science in natural resource and mineral exploration.
Dr. Li's presentation introduced a solution to web delivery of spatial information and functionality based on the SVG specification (Scalable Vector Graphics). The study examines design and implementation of an SVG spatial representation model, SVG topological model, geographical coordinate transform, SVG Symbol base, and interactive displacement and storage structure for visualization databases. She demonstrated some examples of Web mapping, spatial analysis, 3D modeling, spatial information, and functionality services with SVG.
