Presentation Transcript

  1. Introduction to GIS and ArcGIS • Overview • What is GIS • What is ArcGIS • ArcGIS Interface

  2. coordinate data each feature hasa record tabular data What is GIS and how does GIS work? Combination of and

  3. data people hardware software methods GIS – an integration of five basic components

  4. What are GIS Functions • capture, • store, • query, • analyze, • display • output

  5. Capturing data

  6. Vector formats • Discrete representation of reality Pixels – photo images • Raster formats • Use square cells (grids, pixels) to model reality Storing data

  7. Find Tail Tree Locations with DBH>18” Query • Identifying specific features • Where is parcel No. 2945 Identifying features based on conditions

  8. Analysis • Proximity : which roads are within a 100 ft from a stream • Overlay: combines the features of two or more layers to create a new layer that contains the attributes of both • Network: examines how linear features are connected

  9. Display • Maps • Graphs • Reports/Tables

  10. Examples of GIS maps surface drapes & 3-D modeling

  11. Examples of GIS generated maps detailedtopographic maps

  12. Output • Paper map • Internet • Image (cc.jpg, cc.pdf) • Document (cc.mxd) • Poster

  13. Introduction to GIS and ArcGIS • Overview • What is GIS • What is ArcGIS • ArcGIS Interface

  14. ArcGIS Desktop ArcGIS Engine EXTENSIONS EXTENSIONS CustomApplication ArcInfo ArcEditor ArcView ArcReader ArcPad WebBrowser ArcObjects Network ArcGIS Server ArcIMS ArcSDE RDBMS What is ArcGIS? ArcGIS Clients Components Application/Data Servers

  15. Extensions -> Increase Functionality • Functionality not included in the core ArcGIS product can increase productivity • Some extensions are built-in, but just need to be enabled • Other extensions are available for free (web); some are available for sale • We will be using several extensions during the course

  16. ArcInfo ArcEditor ArcView ArcGIS Desktop Products Increased Functionality

  17. ArcCatalog-window to database ArcInfo ArcMap-displaying ArcEditor ArcView All ArcGIS products share common applications ArcToolbox-geographic processing functions

  18. What is unique about ArcGIS GIS? • GUI (Graphic User Interface) • Desktop Use • Customization & Programming • Extensions to Increase Functionality • Scalability

  19. GUI • ArcGIS uses a Graphical User Interface (GUI). • Instead of typed commands, menus, buttons, and tools are used. • Provides access to most controls, functionality, and operations • Each document type in ArcGIS has its own GUI controls. • Beware: • The ArcGIS GUI is complicated and many-layered. • There is no command-line control; all automation must be scripted.

  20. Desktop Use • Unlike most major GIS software of the past, ArcGIS will run on a desktop computer. • Desktop computers (PCs) are: • cheap • easy to administer • common • easy to use_

  21. Customization & Programming • Many functions are not available from the GUI • Custom functions and operations can be created with various programming languages • Repetitive tasks can be automated • New functions and operations can be added to the GUI menus, buttons, and tools • Entire new applications can be developed • Beware: • Scripting is not easy to learn

  22. ArcGIS Desktop ArcGIS Engine EXTENSIONS EXTENSIONS CustomApplication ArcInfo ArcEditor ArcView ArcReader ArcPad WebBrowser ArcObjects Network ArcGIS Server ArcIMS ArcSDE RDBMS Scalability The ArcGIS suite contains • Desktop application • (we will be using this quarter) • Data server application (ArcSDE) • Application servers (ArcGIS Server) • Internet mapping servers (ArcIMS)_

  23. Introduction to GIS and ArcGIS • Overview • What is GIS • What is ArcGIS • ArcGIS Interface

  24. The ArcGIS Interface

  25. The ArcGIS Interface ArcMap – viewing, editing, processing…..

  26. The ArcGIS Interface ArcCatalog – Data Management Editing Processing

  27. GUI • table of contents • map display • data frame • layer • scale The ArcMap Interface

  28. Toolbars • demonstration of help tips

  29. GUI • catalog tree • catalog view • foldersdata sources The ArcCatalog Interface

  30. The ArcCatalog Interface • contents mode

  31. The ArcCatalog Interface • Preview geography mode

  32. The ArcCatalog Interface • preview table mode

  33. The ArcCatalog Interface • metadata mode

  34. ArcToolbox & Geoprocessing • Most geoprocessing tasks are accessed through ArcToolbox

  35. ArcToolbox & Geoprocessing • ArcToolboxcan be “docked”in ArcMapor ArcCatalog

  36. ArcToolbox & Geoprocessing • Geoprocessing tasks can also be performed using the command line

  37. ArcScene • Application for viewing data in 3 dimensions in “real time”

  38. ArcGlobe • Application for viewing global data in 3 dimensions in “real time”
