Our Students

Our students are an invaluable asset to the Center for Spatial Planning Analytics and Visualization. We routinely employ 10-20 undergraduate and graduate students per semester from a variety of colleges and schools across Georgia Tech, with the majority enrolled in the School of City and Regional Planning graduate program.  Students work on a variety of projects and perform a multitude of tasks ranging from software development to writing and editing journal articles to spatial modeling to image processing to serving as teaching assistants. These incredibly bright students are a vital part of the Center's ongoing success and we are fortunate to have them spend their time at Georgia Tech working for us.
