The key to sustaining a business is to know one's customers. By geographically referencing customer records, and linking them to data such as demographics, GIS enables business enterprises to evaluate their client-catchment areas. This course provides an introduction to GIS in the business environment, by combining lecture material, readings from the professional literature, site visits for the evaluation of systems, and labs designed to provide practical and technical competence. There is a 25 dollar lab fee for this course.
