  1. Database design
    Logical representation of data in a database
  2. Application domain
    realm or area of use of an applicatio, such as business, health info, science or land parcel management
  3. Thematic layers
    Form basis for organizing geographic representations (i.e. soil types or satellite imagery)
  4. Common elements of gdb
    feature classes, feat datasets, topologies, networks, raster datasets and catalogs
  5. 3 methods to create gdb
    create schema with arccatalog, import existing data, use CASE tools
  6. design patterns
    recurring solutions to software design problems frequently encountered in app development
  7. 5 gdb features promoted by esri
    improved management, extended functionality, integrated data structure, consistent with trends in IT, database for next 50 years
  8. 6 advantages of gdb
    all data centrally stored and managed; subtypes, domains and alidation rules help with db integrity; continuous data sets; versioning; feature-linked annotation; accessed through standard menus and tools in esri products
  9. 2 ways to automate
    programming, scripting
  10. programming
    compiled, manifested like .exe
  11. scripting
    interpreted, can be edited in textpad
  12. geoprocessing
    any gis operation used to manipulate data stored in a GIS workspace.
  13. why automate?
    large datasets can take long time to manually process, an overall geoprocessing sequence could involve discrete steps that must be done over and over on several datasets (iteration)
  14. software programming languages
    system language (C++, Java) and scripting language (python and perl)
  15. script?
    set of instructions written in plain text, interpreted or compiled at run time
  16. COM (Component Object Model)
    • binary standard that enables software components to interoperate in a networked environment. ArcGIS uses COM.
    • not language
  17. ArcPy
    single access point for exectutio of any geoprocessing tool.
  18. sdss
    spatial decision support system
  19. ahp
    analytic hierarchy process
  20. decision making involves:
    intelligence: identify and define potential problems/opportunities

    design: develop alternative solutions

    choice: select course of action
  21. problem solving
    implementation: take action

    monitoring: evaluate implementation
  22. types of decisions
    • structured
    • unstructured
    • semistructured
  23. structured decision
    use a rule or procedure or quant method

    e.g. thermostat
  24. unstructured decision
    deal with unusual or exceptional situations

    e.g. coin toss?
  25. semi-structured decision

    e.g. which restaurant, which gis class
  26. decisions support system
    information system that combines data, analytical tools and models to support semi-structured and unstructured decision making.
  27. 4 dss components
    user interface

    information system

    modeling system

    analysis system
  28. group decision support system
  29. 7 gdss components
    • information system
    • model system
    • analysis system
    • dialogue manager
    • communication capability
    • special software
    • user interface.
  30. sdss
    spatial decision support system

    adds location
  31. 5 sdss components
    • information system
    • model system
    • spatial system
    • analysis system
    • user interface

    e.g. AHP
  32. AHP
    • Analytical hierarcy process: helps people set priorities
    • when both qual and quant need to be considered
  33. 7 step in AHP Process (on final)
    • state goal
    • define criteria
    • identify the alternatives
    • arrange info in hierarchical tree
    • make pairwise comparisons
    • construct matrix of comparison
    • calculate priorites
  34. arcgis server components
    • gis server
    • web server
    • clients
  35. thin clients
    i.e. web browsers
  36. thick clients
    stand alone apps
  37. hybrids
    applets loaded by browser
  38. 5 standard dem generation technique
