GEOG 482L: Principles of Geographic Information Science Fall 2011 Time: Tues / Thur 12:30-1:50 Lab: Thur 2:00-3:50 Location: AHF B57A (access through AHF B55) Instructor: Dr. Andrew Curtis Office: 448B Kaprielian Hall Office Hours: Tuesday and Thursday 11:15-12:15, or by appointment Phone: 626 429 9476 Email: ajcurtis@usc.edu Course Syllabus General Focus Many academic topics are inherently spatial – both in terms of the physical processes, and the human implications. Hurricane tracks, the location of fault lines, how tornadoes are generated – these are patterns or processes that have or leave spatial footprints. Where people live in relation to potential hazards or the societal impact left after a disaster can again be described in terms of spatial patterns. Within these patterns are human places, cultures, and interactions. As geographers we have the technologies and spatial skills to map, predict, and ultimately understand these landscapes. This course will investigate one of the major geospatial tools we have at our disposal This class has two objectives; to present an overview of the conceptual aspects of GIS and provide students with a working knowledge of ArcGIS software. Any student requesting academic accommodations based on a disability is required to register with Disability Services and Programs (DSP) each semester. A letter of verification for approved accommodations can be obtained from DSP, and it should be delivered to me early in the semester. DSP is located in STU 301 and is open 8:30 to 5:00 pm, Monday through Friday (740-0776; study@usc.edu). Statement of Purpose Each class will consist of a mixture of spatial topics followed by software instruction based on the previous conceptual discussion. This will be a fluid process that allows students to understand why a topic is important, and then immediately act on that topic. The lab section will consist of a hands-on practical session that will polish your GIS skills. A learning objective of this class is that you will become competent with the software, and develop a spatial science understanding of why you would use a GIS. In other words, you will learn enough to support your research, or that of others, or even to find employment. Each student is encouraged to work with a friend. Readings: All students are expected to read the academic papers that will accompany each week’s topic. In addition, you might find the following useful (the publishers’ blurb): GIS Tutorial 1: Basic Workbook, Fourth Edition meets a growing demand for effective GIS training by providing tutorials and assignments that teach you how to collect data, create maps, and perform spatial analysis. Presented in a step-by-step format, the book can be adapted to your specific needs, whether these involve learning GIS in a classroom or using the book for independent study. Updated for ArcGIS 10, this workbook demonstrates a range of GIS functionality, from querying interactive maps to running geoprocessing tools, and it introduces ArcGIS extensions for advanced analysis. Reader-friendly exercises make GIS Tutorial 1 the perfect choice for beginners. Also included is a fully functioning 180-day trial version of ArcGIS 10 software on DVD and CD of data for working through the exercises.

These will consist of techniques you have been taught in class. The final exam will also include theoretical questions based from class readings and lectures. There will be three exercises and a final research project which you will present to the class at the end of the course. Students may work in groups except for on the inclass tests. During these tests any and all documentation (class notes, texts) are permissible – just no talking. There will be no “extra credit” – if you don’t come to class early in the semester, or if you don’t hand in satisfactory work, be prepared to live with those consequences. If you have a particular problem during the semester, I will always work with you at that time, not later in retrospect. Treat this like a Stats class….if you miss a week, it is hard to catch up… Therefore : 3 in-class tests Final exam 3 labs 1 research project 30% 10% 30% 30% Grade Distribution: A = > 94 C = 74-77.9 A- = 91-93.9 B+ = 88-90.9 B = 84-87.9 C- = 71-73.9 D+ = 68-70.9 D = 64-67.9 B- = 81-83.9 C+ = 78-80.9 D- = 61-63.9 F = < 61 Please note that you: (1) are strongly encouraged to keep a copy of all materials submitted for grading; and (2) you must obtain at least a D grade (≥ 61%) on the final exam in order to pass the course as a whole. Deadlines Deadlines will be set in lecture / lab. These will be non-negotiable. For every day an exercise is handed in late, it will be graded down by 20%. After 5 days – you have lost all possible points. Obviously emergencies are handled on a case-by-case basis. Please contact me with any problems you may encounter as soon as you are aware of them. If you have to miss an exam (by prior agreement with me) the multiple choice exam will be replaced by an essay exam covering similar material.

If you put in the time and work hard, I will do my best to make it a valuable experience for you.
