4. Details at gis.tufts.edu Instruction and tutorials Consulting for individual faculty, students, and research teams Data acquisition and distribution Software distribution and management Class lectures on spatial analysis and GIS Course activity advising and development Application development (e.g., Google Earth for teaching) Research design and database design consultations GIS Support for Research and Teaching

5. What is GIS? A spatial database GIS helps you integrate tabular and spatial information Display information on a map Explore spatial relationships (e.g., children’s access to open space) Combine data for traditional statistical analysis (e.g., toxic releases from specific sites combined with census data) Perform spatial analysis

6. Census data in GIS spatial + tabular information = spatial database

7. Census data in GIS Display of information

8. Integrating data using GIS Austin, Texas example Concern about development impacts on watersheds, water quality, and urban flooding Use GIS to geocode building permits Spatial overlay combines watershed information with building permit information The result is a map and new data set showing the amount of new construction by watershed

9. Austin Watersheds

10. Austin Watersheds & Building Permits

11. New Construction in Austin Watersheds

12. Using historical data in GIS Austin, Texas example Scanning a 1927 “land use” map of Austin, Texas, and georeferencing in GIS The 1927 Plan for Austin called for segregation of facilities by race to encourage more segregation Comparing locations of African Americans in the 1927 maps and 1990 census maps enables analysis of the impact of these planning policies

13. 1927 Austin “Land Use” (from the City Plan of that year) “Segregation a problem” – not enough of it….

14. 1990 African American population in Central Austin

15. Mapping walkable area for three schools by street network and “crow flies” buffer Rings represent ¼ and ½ mile buffers, shaded areas represent ¼ and ½ mile street network around each school Spatial Analysis in GIS Example - Exploring the built environment and walking

16. Measuring street connectivity as a possible factor in how much people walk in their neighborhoods Start with street network

17. Create a node for each street intersection Spatial Analysis in GIS Example - Exploring the built environment and walking

18. Create a density surface of street nodes

19. Spatial Analysis in GIS Example - Exploring the built environment and walking The result is a street intersection density surface (this example is Houston, Texas)

20. Spatial Analysis in GIS Example - Exploring the built environment and walking This can be combined with socio- economic data from the Census…

21. Spatial Analysis in GIS Example - Exploring the built environment and walking To show a matrix of street connectivity and socio-economic status for each area of Houston

22. Example of data designed for spatial analysis The National Hydrography Data Set A new water-related data source to support hydrological analysis Water “flow” lines are designed to model the flow of water through a system – follow a raindrop from the mountains to the sea The data set includes hyper-links to real-time data from stream and precipitation gauges

35. Teaching & Learning with Google Earth Geography 2.0 Useful for displaying and interacting with geographic information Global & regional study areas Natural sciences, social sciences, and humanities Unlike a wall map, it is customizable, portable, and interactive Free, easy to use, and fun Google Earth can be downloaded from: http://earth.google.com/
