1. Introduction to GIS/GPS Mr. Canada World Geography Burris Laboratory School

2. KEY WORDS  GIS  GIS Data  Spatial Data  Accuracy vs. Precision  Scale  Projection  GPS  ArcGIS Online  Table of Contents  Layer(s)  Feature(s)

3. What is GIS? G eographic I nformation S ystem

4. GIS Explained  In short: “ computerized mapping software ”  GIS is a set of software and tools used to capture, store, manipulate, analyze, and display spatial data.  In this class, we will explore capturing and displaying spatial data

5. Demographics

6. Environmental / Natural Disasters

7. Politics

8. Understanding GIS Data  GIS represents the real world using three types of geometry :  Points  Lines  Polygons / Areas  OR cells  Raster - graphic images

9. Brainstorm! What are some other examples of points, lines, and polygons?

10. What is Spatial Data? Data that has reference to a location on Earth

11. Spatial Data Components  Projection : the method by which the curved 3-D surface of the earth is represented by X,Y coordinates on a 2-D flat map/screen  Distortion is inevitable!  Scale : the ratio of distance on a map to the equivalent distance on the ground  Accuracy : how well data matches the real world  Precision: reproducibility of data

12. High accuracy, low precision Low accuracy, high precision

13. Why GIS is Important  GIS adds “space” to research dimensions  Geographical significance & patterns  Does location make any difference?  i.e. Real estate – location, location, location..  Are there any patterns?  i.e. Migration patterns? How did the disease spread?  Geographical relationships  Are A and B in this location related?  i.e. Crime rate and average housing value  Prediction & Information management  How many people will be affected by flooding?

14. GPS Exercise Friday April 11 th and Monday April 14 th

16. GPS Receivers  Handheld devices using satellite signals to calculate location  Latitude: distance North / South of the Equator  90 degrees = Poles  0 degree = Equator  Longitude: distance East / West of the Prime Meridian  0 degree = Prime Meridian (Greenwich, UK)  180 degrees = International Date Line

18. How to Read Lat / Long  Degrees, Minutes, Seconds  0 – 90 degrees North / South  0 – 180 degrees East / West  60 Minutes in a degree  60 Seconds in a minute 43°52'49'' N, 103°27'33'' W

20. Activity Description  Identify locations on Ball State campus using Garmin GPS receivers, given only latitude and longitude points  Coordinate points are predetermined!  All locations will be south of Riverside Ave

22. Using Your Garmin  “Hot” and “Cold”  Watch your latitude and longitude points shift until you have reached your location

24. Directions 1. Turn on your receiver by holding down the power button on the right-hand side (you will hear a beep) 2. Use the Page button to navigate to the screen with “Speed” “Elevation” and “Location”  “Location” is what you will be using *The main menu has other features! Navigate using the joystick!

25. Reminders  We will be going outside THIS FRIDAY and NEXT MONDAY  Dress accordingly for the weather  Jacket if it’s cold  Closed toe shoes  Dates are subject to change  Sign up for receivers!

26. Mapping Exercise Thursday April 17 th and Friday April 18 th

27. ArcGIS Online  Web-based mapping program used to create maps, explore data, and share maps online

28. Contents of a Map  Table of Contents : Area that organizes map data  Layer : visual representation of a geographic dataset in any digital map environment  Feature : A representation of a real-world object on a map  “Place” on the map  Attribute Table : A database or tabular file containing information about a set of geographic features

29. Activity Description  Create a walking tour map of Ball State University in ArcGIS Online using the following criteria:  Tour must begin and end at the Administration Building  Major roadways may not be used, sidewalks only!  Tour must be between 3 and 8 kilometers in length (hint: use the measure tool)  Tour must include 3 of the featured point locations from our field day  Map must be emailed to instructors to upload to class website

30. Accessing ArcGIS Online  BSU GIS log-on  Access to all BSU GIS maps and data

31. Starting Your Map

32. Using Tools  Show table  Under prospective layer  Measure  Area, length, location  Change symbols  Under prospective layer

33. Saving Your Work  Take a screenshot (Print Screen button)  Open photo in Microsoft Paint  Crop photo  Save as Jpeg  Attach and email Jpeg to:  burrisgeography@gmail.com
