1. What is GIS? CONS 340 Lecture 1

2. Abstract concepts Goals Understand basic concepts of GIS design Database Development Cartographic Modeling Prepared for future coursework Application Goals Introduction, not GIS proficiency Application of broader issues in lecture, through the software Software utilized ArcGIS 10.1 ArcCatalog ArcMap ArcScene ArcGlobe LecturesLabs Course Organization

3. Evaluation Two exams Final Exam is cumulative but emphasizes the last half of class Lab Attendance is mandatory! Don’t fall behind – we have a lot of ground to cover

5. Today’s Learning Objectives By the end of today’s class you should be able to: Accept that GIS data is NOT reality Explain the five components of a GIS List the three main components of geographic data Summarize what a GIS should be able to do

6. GIS is really about how we conceive spatial information Cognitive mapping How do we make sense of our world Two tracks in the brain What vs. Where

11. This include concepts as well Courses enroll in Students Programs have consist of

12. GIS concepts are not new! In the London Cholera epidemic of 1854 Dr. John Snow was able to locate the source of a cholera outbreak by plotting the locations of fatal cases in relationship to nearby wells. Cholera death Water pump +

15. Hardware & Software Hardware Software

16. Procedures GIS analysis requires well-defined, consistent methods to produce correct and reproducible results. We will spend much of this course learning procedures

17. Data This is by far the most important aspect of GIS Without data we can’t do anything! Approximate time breakdown of most GIS projects: 80% = Database development 10% = Data analysis 10% = Cartographic production

19. There are three main components to geographic data: www.esri.com

20. GIS data is organized in Layers www.esri.com

21. Database “ Not Easy to Interpret”

22. Visualization “Worth a Thousand Words”

23. What can a GIS do? A GIS should be able to:  Capture data  Store data  Query data  Analyze data  Display data  Output data

24. Capturing Data Digitizing Heads up Tablet Scanning Tabular GPS Downloading

25. Storing Data

26. Querying Data SELECT CntryName, PopCntry FROM Countries WHERE Landlocked=No ORDER BY CntryName

27. Analyzing Data Proximity Overlay Etc.

28. Displaying Data Graphs Charts Tables Maps Etc.

29. Outputting Data Sharing the results of your geographic labor is one of the primary justifications for spending resources on a GIS.
