1. Lecture 7 Basic GIS Analysis Operations http://www.csiss.org/classics/

2. Analysis of GIS data Identify Find Query – attribute Query – spatial Table operations  Join  Spatial join  Summarize and other statistics Symbology, classificaion in making a map

3. Identify

4. Spatial Select

5. Find 2 3 4 5 6

6. Labels Double-click

7. Labels - Population

8. Combine values with text with &

9. Label with multiple values "Population: " & [POP1990] & vbcrlf & "County: " & [NAME] & connects two text strings Vbcrlf – visual basic carriage return line feed (next line) Fields [ ] Strings “ “

10. Attribute query

12. Spatial query Use points, lines, and polygons to select other points, lines, and polygons. Use a relationship  Intersecting  Inside  Neighbors  Within a distance of

13. Spatial query -Intersect Layer 1 Relationship Layer 2 Result

14. Spatial query - Intersect result Counties that interstate 5 crosses

15. Spatial query - Contains Cities inside San Diego county

16. Spatial query - Near Cities within 2 miles of Interstate 5

17. Spatial query - Near Cities within 1 mile of Interstate 5 Just those cities, in their own shapefile How’d they do that?

18. Analyze result – Export to shapefile

19. Analyze result – New shapefile

20. Analyze result – Create a report

21. Report properties – fields and order

22. Report

23. Create a chart

24. Chart wizard

25. Chart

26. Table operations - Join Common field (primary and foreign key) One to one relationship (one county has one census record) Fields from one table are appended to the other table Bring spatial and attribute data together

27. Table operations - Join Matching records merge into the one attribute table

28. Table operations – Spatial Join Common location One to Many Relationship (One county has hundreds of quakes) Fields from one table are appended to the other table Bring spatial and spatial data together

29. Spatial Join tables Common location

30. One spatially joined table Matching records merge into the one attribute table

31. Summarize a field How many quakes per county?

32. Build a statistics/summary table

33. Join summary table and county table

34. Symbolize – Quakes per county

35. Normalize by area – Quakes per square mile

36. Normalize by area – Quakes per person
