Geog 176B - Technical Issues in Geographic Information Systems, 4.0, Goodchild/Clarke Study of the technical issues underlying Geographic Information Systems, including coordinate systems and analytic geometry, database models and structures, algorithms and analytical procedures. Laboratory analysis of digital geographic information from physical and social sources, emphasizing the use of standard geographic information system software to illustrate techniques of spatial analysis, map digitizing, digital map display and decision support. Geog 176C - GIS Design and Applications, 5.0, Clarke Applying GIS theory and techniques to solve spatial problems in land and resource management, utilities and municipal government. Lectures will cover all stages of a GIS project, e.g. planning, design, and analysis, and presentation of results. In labs, students collaborate in groups to design, develop and present a GIS pilot study. What will I learn in 176A? • An overview of GIS • How GIS data are captured, stored, • Where to go for information (self-help) • GIS software and how it works • Where GIS is going • How to use a basic GIS • GIS problem solving Learning by Listening
