Jason VanHorn is an expert in cartography, geographic information systems (GISs), and spatial analysis. He holds a PhD from the Ohio State University, a Master of Science from Texas A&M University, and a Bachelor of Arts from Indiana University. Since completing his PhD, he has taught and established GIS research as an associate professor of geography at Calvin College, an undergraduate university in Grand Rapids, Michigan. Professor VanHorn's research foci involve 2D and 3D visualization and the spatial analysis of phenomena across space and time. His students learn foundational skills in mapping, cartographic theory and geodatabase management, usage and design, and advanced concepts that bridge the gap between rudimentary GIS skills and geospatial thinking. He has directed 25 different GIS research projects during the last seven years. He has worked extensively with Ethiopian spatial data, having co-led the January 2012 Digital Atlas Workshop at Bahir Dar University and was the lead lecturer for the Ethiopian National Geospatial Standards Summit in December 2013 in Addis Ababa. He and his students have produced a series of national digital atlases with spatial data for Ethiopia, Eritrea, Liberia, Madagascar, Thailand, Nepal, and Niger.
