Geographers examine the spatial relationships between people, places, environments and economies using innovative conceptual and technological approaches. Exciting technological changes, from computer mapping software like Google Earth, to satellite image processing, and global positioning systems (GPS), make geography a fascinating discipline to study. DePaul's geographers share a commitment to 'hands on' teaching and research that makes a world of difference for the people, places, environments and processes that we study. Geographers apply methods such as observation, visualization, analysis, and modeling to explain the spatial organization of human and physical environments.
