Presentation Transcript

  1. Introduction to GIS and ArcGIS • How a GIS works • Introduction to ArcGIS

  2. A GIS integrates five basic components methods software hardware data people

  3. Data

  4. Types of datasets Vector formats (“feature classes”) Points Lines (”arcs”) Polygons

  5. Types of datasets • Raster formats • Matrices of square cells (grids, pixels)

  6. Types of datasets Attribute tables: tables of data describing spatial features

  7. Methods

  8. Basic GIS Functions Capture Store Query Analyze Display Output

  9. Capturing data Digital images Paper maps GIS GPS output Coordinate lists

  10. Query Identifying specific features Where is parcel No. 2945? Identifying features based on conditions Find all trees with DBH > 35 cm

  11. 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 (intersections, unions…) Network: examines how linear features are connected

  12. Analysis

  13. Analysis

  14. Display Maps Graphs Reports/Tables

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

  16. Examples of GIS generated maps detailedtopographic maps

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

  18. How a GIS works • Introduction to ArcGIS

  19. 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

  20. ArcInfo ArcEditor ArcView ArcGIS Desktop Products Increased Functionality

  21. ArcInfo ArcEditor ArcView The history of ESRI products ArcView ArcGIS ArcInfo time

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

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

  24. GUI • Beware: • The ArcGIS GUI is complicated and many-layered. • There is no command-line control; all automation must be scripted.

  25. 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 • But: • Scripting is not easy to learn

  26. 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

  27. ArcGIS Desktop CustomApplication ArcInfo ArcObjects ArcEditor Network ArcGIS Server ArcIMS ArcSDE ArcView ArcReader ArcPad WebBrowser 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)

  28. GIS software
