8. What is GIS? What is GIScience? Longley et al., GI Systems & Science on reserve, VR 136 Place Matters…, VR 135

10. Some Basic GIS Concepts... Mapping is key but is NOT the whole story. A GIS is NOT simply for MAKING maps maps at different scales, projections, colors … not simply for STORING maps or images. In fact, it stores the DATA from which these are created.

11. An Analysis Tool... for every piece of data it specifies: what it is where it is how it relates to other pieces of data things in common see spatial relationships or create NEW relationships

12. Geographic Information System Container of data Container of maps Inventory of geographically distributed features and facilities Computerized tool to automate time-consuming tasks Analysis tools for solving geographic problems Spatial decision support system Method for revealing patterns and processes in geographic information

13. Geographic Information System Organized collection of Software Hardware Network Data People Procedures People Software Data Procedures Hardware Network

14. Major Questions for a GIS: What exists at a certain location? Where are certain conditions satisfied? What has changed in a place over time? What spatial patterns exist? What if this condition occurred at this place? (modelling, hypothesis testing)

15. For example... Toxic Substance Locations: District 24 District 16 14 George Boulevard Proposed School Locations: 124 Elm Street 35 White Road

16. School Locations Toxic Substances

17. Information on the World How it looks – Form or Pattern How it works – Process Knowledge about process more valuable than form, because can be used to predict GIS combine General scientific knowledge in software Specific information in databases

18. Global Accessibility

19. Featured in Science, vol 323, January, 2009

20. Major Questions for YOU... What ARE my questions? How much data do I need and of what quality? How can I combine my data to answer my questions?

21. The Process of GIS (i.e., GIScience) Think about a place or a topic... Ask a question about it... Analyze data to make a map... Explore the patterns that appear... Enhance the data or modify the analysis... Ask a new question … Repeat...

22. Defining GIS Different definitions of a GIS have evolved in different areas and disciplines. map coordinates, Database of spatial and often non-spatial, computer-based link between them. All GIS definitions recognize that spatial data are unique because they are linked to maps.

23. Spatial/Geographic/Geospatial Data? Latitude and longitude Street address x and y coordinates Range and township Location shown on a map

24. Non-spatial Data? Name Gender Income SSN or student ID number Political party

25. Attributes in a Database Attribute data are stored logically in flat files. i.e., matrix of numbers and values stored in rows and columns, like a spreadsheet.

26. The Data Model A conceptual description (mental model) of how spatial data are organized for use by the GIS GISs have traditionally used either “field” or “object” data models

27. A Field Data Model Uses a Raster or Grid Data Structure.

28. “Rasters are Faster...” maps directly onto computer memory structure (array). easy to understand, read, write, draw

32. Rasters are Faster... natural for scanned or remotely sensed data. continuous surfaces (e.g., topography) spatial analytical operations are faster. compression is easier “Rasters tell WHAT occurs everywhere.”

34. “ Rasters are Faster, but Vectors are Correcter! ” Can represent point, line, and area features more accurately. Far more efficient than grids. Not where EVERYTHING occurs (continuous phenomena)… But WHAT occurs everywhere … Work well with GPS receivers.

35. Feature TypeSingle PartMulti-Part Point Line Area Annotation H I G H W A Y 10 Object/Vector Feature Types

37. 3 Distinguishing Characteristics of a GIS vs. Other Systems 1.provides links between points, lines, areas, grids and their ATTRIBUTES in a database

38. 2. provides algorithms for ANALYSIS of spatial data

39. 3. “spatially intelligent” - “thinks” points, lines, areas, grids are actual spots on Earth’s surface - e.g., switching projections, computing distances

40. GIS “Layers,”“Themes,”“Overlays”

41. GIS is a multi-Billion dollar business. annual software revenues top $1 billion, increasing ~14% yearly ESRI and Intergraph software revenues account for 1/2 of industry total GIS industry now at $7 BILLION

42. Open Source GIS quantum GIS - qgis.org uDIG - uDIG.refractions.net GRASS - grass.itc.it

43. GIS as an approach to science Geographic Information Science is research both on and with GIS. “the generic issues that surround the use of GIS technology, impede its successful implementation, or emerge from an understanding of its potential capabilities.” (Goodchild, 1992)

44. “GISci” “GIScience” “GIS & T” Geographic information science U.S., geography, UCGIS to GIS as statistics is to the statistical packages The science behind the systems Fundamental issues arising from use The science that is done with the technology Systematic study of geographic information using scientific methods

45. GIScience - Contributing Disciplines GISystems Remote Sensing Cartography Surveying (Geomatics) Geodesy (GPS) Landscape Ecology Statistics Mathematics Computer Science Information Science Operations Research Management Science Psychology, Sociology More …
