2. Introduction to GIS Course Logistics Web site: uvm.edu/~nr143 –Syllabus –Lectures and labs –Links, news, assignment upload area –Password –A work in progress (some material from S09) No required textbook © 2007 Austin Troy

3. Introduction to GIS More Logistics TA Office hours Classroom expectations –Participate (or at least pay attention) –Be on time (attendance counts) –Cell phones, computers, & other distractions Grading, exams, late policy

4. Introduction to GIS Still More Logistics Periodic assignments (more info later) Labs –During lab periods or on your own –Optionally work with a partner if necessary Labs/assignments due in a week (usually) Scores on Blackboard (bb.uvm.edu)

5. Introduction to GIS Philosophical Underpinnings Anyone can learn to push buttons Lectures teach concepts; labs teach mechanics (practice) Goal: Knowledgeable GIS users Academic integrity; Think/care/act Who is this guy?

6. Introduction to GIS © 2007 Austin Troy Source: adapted from UC Berkeley GIS Center What is GIS? (some boring definitions) The complete sequence of components for acquiring, processing, storing and managing data (Star and Estes, 1990) It is a configuration of computer hardware and software specifically designed for the acquisition, maintenance and use of cartographic data, (Tomlin, 1990) It is a set of computer tools for collecting, storing, retrieving at will, transforming and displaying spatial data from the real for a particular set of purposes, (Burrough et al. 1998) A system of hardware, software, data, people, organizations and institutional arrangements for collecting, storing, analyzing and disseminating information about areas of the earth.
