1. 1 Introduction To Geographical Data and TEISS Maps Angelique Luedeker, ITEP/TAMS Center

2. 2 Homework Discussion Would anyone like to share their list of what facilities are on the reservation as reported in the NEI data? Are there any questions on the homework?

3. 3 GIS Definitions A G eographic I nformation S ystem (GIS) is used for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to Earth OR A computer system capable of holding and using data describing places on the earth's surface OR Graphic representation of where features are, explicitly and relative to one another.

4. 4 Foundation of GIS Geographic Data - referenced spatially by a coordinate system Latitude and Longitude Example: 56°27'40" and 116°11'25" Universal Transverse Mercator (UTM) Example: 545,000.000 and 6,453,254.000 Legal Survey Description Example: T122N, R71W, S12 Attribute Data Characteristics of the Feature or Map Component Map Legend Links the Attributes to the Geographic Data

5. 5 Datum Reference specifications of measurement system, usually a system of coordinate positions on a surface (horizontal datum) or heights above or below a surface (vertical datum) North American Datum of 1927 (NAD 27) Zero based on geographic center of lower 48, in Kansas World Geodetic System of 1984 (WGS 84) and the North American Datum of 1983 (NAD 83) Zero is based on Earth’s center of gravity These work well with GPS In U.S., for a given point, coordinates measured with NAD 27 and those measured with WGS 84 or NAD 83 can be several hundred feet apart, depending on where the point is Source: ESRI @ http://support.esri.com/index.cfm?fa=knowledgebase.gisDictionary.search&searchTerm=datum

6. 6 Different Data NAD 27 NAD 83 + WGS 84

7. 7 Layers Representation of a dataset in a digital map environment Components of the legend Theme Overlays Composed of visual representation and attribute data

8. 8 Visualization of Layers “Mini-maps” or “sub-maps” Come together to make a map that answers a question

9. 9 TEISS Map Interface What are the different toolbars? How do you display or hide layers? How do you display or hide labels? How do you customize the appearance of layers? How do you customize the appearance of labels? How do you import a map? How do you export a map?

11. 11 Select Zoom In Zoom Out Pan Zoom In to Site Domain Zoom out to Site Domain DeleteCan also use “Delete” button on keyboard Draw Rectangle Draw Circle Draw Irregular Shape Text Box Marker Mark a spot on the map Draw Arrow Compass Arrow Overlay Control Another way to customize view instead of using file tree Measure Distance Import Map Define Site Domain Customize Colors Query (Search) for specific polluter Annotation Bar Explained

12. 12 Click and drag to move the layers Working with Layers

13. 13 Now the tribes are on top of all layers

14. 14 TopVisible BottomHidden

15. 15 Click the + sign to expand file tree. Double click on a symbol to change it. Click box next to “Uniform Color” to change it

16. 16 Click on the color to change it

17. 17 Click on Drop Down box to change Shade Style Then click “OK” button

18. 18 Now the tribes are red and transparent

19. 19 To undisplay a layer, uncheck the box next to it in file tree

20. 20 Click “Labels” tab for Labels File Tree It works the same as Overlays File Tree The labels for the tribes are displayed because they have a check Working with Labels

21. 21 Double-click on an Item to customize it

22. 22 Success

23. 23 Click on Import -> Base Maps -> Shapefile Importing Maps

24. 24 Click “Open” button

25. 25 Find the file and click “Open” button

26. 26 If you need to convert the shapefile, click on “Convert” button Have to convert because these don’t match

27. 27 TEISS default for drawing its maps

28. 28 Input your shapefile’s coordinate system parameters in here. The boxes will change depending on what you have to enter. Then click the “OK” button

29. 29 Click the “OK” button These roughly match now. This is good.

30. 30 If everything lines up right, you got the correct projection

31. 31 Tips on Modifying the TEISS Map Interface There is not an “Undo” button When you click on the Apply button or the OK button, you have already saved the change to the map If you make changes you do not like and want to go back to the defaults, there is a Default button for each layer

32. 32 Exporting the Map Option 1: Simple Map From the TEISS menu, select Export, then Copy to File, then select the type of file In the next screen, navigate to where you want to save the map and give it a name Leave the defaults in the next screen

33. 33 Exporting the Map (cont.) Option 2: Map With More From the TEISS menu, select File, then Print Customize the map, the Preferences button has even more options Click on the Save to File icon that looks like a computer disk

34. 34 Exporting the Map (cont.) Either of these files can be imported into documents Select Insert from the menu, then selecting Picture, From File

35. 35 Homework due in 5 days: Modify the TEISS map to how you want it to look for your QAPP and written EI report Export the map Email the instructors the exported map
