  1. Introduction to GEOGRAPHIC INFORMATION SYSTEMS ARC 383 Can Kara Faculty of Architecture 2011 c_kara77@yahoo.com Arch: 383 Introduction to GIS Week2

  2. Software Details ArcGIS Software – licenses and applications Common GIS data structures Data types supported by ArcGIS ArcCatalog and ArcMap user interfaces ArcGIS Desktop Help system

  3. ArcGIS Desktop Software Suite – Applications ArcCatalog: organize and manage GIS data ArcMap: view, edit, and analyze spatial data and create maps

  4. ArcGIS Desktop Software Suite – Applications (cont.) ArcToolbox geoprocessing data conversion defining map projections

  5. Spatial Data Types Supported by ArcGIS Vector Data ArcInfo Coverage ArcViewShapefile ArcGIS Geodatabase CAD data Microstation design files (.dgn) AutoCAD drawing files (.dwg) AutoCAD drawing interchange files (.dxf)

  6. Spatial Data TypesSupported by ArcGIS (cont.) Raster Data Images – e.g., DOQQ’s, DRG’s, (.tif, .bil, .jpg, .sid, etc.); can now be in geodatabases ArcInfo Grid – e.g., DEM’s Tabular Data Comma or tab delimited text (.txt) dBase (.dbf) file containing coordinate data (X,Y coordinate)

  7. ArcCatalog The data management application of ArcGIS Import, export, and preview datasets Drag and drop data into ArcMap Create new spatial datasets View, create, and/or edit metadata

  8. ArcCatalog Interface Viewing Modes Connect to Folder Catalog Tree Data Exploring

  9. ArcCatalog (cont.) Establish folder connections to access data

  10. ArcCatalog (cont.) Create new spatial datasets, e.g., shapefiles

  11. ArcCatalog (cont.) Preview spatial and tabular data

  12. ArcCatalog (cont.) View, create and/or manage metadata

  13. ArcCatalog (cont.) View, create and/or manage metadata

  14. ArcCatalog (cont.) Metadata Content Identification Information Data Quality Information Spatial Data Organization Information Spatial Reference Information Entity and Attribute Information Distribution Information Metadata Reference Information

  15. ArcCatalog (cont.) Launch ArcMap and open the ArcToolbox window

  16. ArcMap ArcGIS application used to display, query, edit, create, and analyze geographic data

  17. Map display Window (Data Frame) ArcMap Interface ArcCatalog Standard Toolbar Data Frame (a group of layers) Table of Contents – Lists layers (stacking order; like a legend) TOC Tabs – different display modes Data Frame display modes – “Data” or “Layout” Status Bar

  18. Map Document Fundamental component of ArcMap Collection of data layers (in data frames) and a cartographic layout Stores references to the locations of the data sources (e.g., shapefiles, coverages, image files, etc.) NOT the data themselves Has .mxd file extension

  19. Map Document

  20. Map Document (cont.) Map Document Properties Data Source Options

  21. ArcMap Toolbars ArcMap provides a number of other toolbars: Draw Editor Layout Effects, etc.

  22. ArcMap Toolbars • Standard toolbar contains buttons and tools that provide fast and easy access to many operations, e.g., Save, Add Data, etc. • Tools toolbar is always active and can be used in either the data or layout view

  23. ArcMap Table of Contents Display tab Data Frame Selection tab Source tab

  24. ArcMap Data View Browse, edit, and analyze the spatial data on a map

  25. ArcMap Layout View Prepare finished maps for reports and publications

  26. ArcMap Interface - Customized

  27. Coordinate Systems (Projections) Geographic – “lat long”, unprojected

  28. Coordinate Systems Projected – UTM, Lambert, Albers…

  29. Data Frame Properties Map units: horizontal measures in which distances are calculated in a data frame Feet, meters, etc. Display units: horizontal measures in which distances are actually displayed on the screen Feet, meters, etc.

  30. Data Frame Properties Map units are set when a coordinate system is specified for a data frame

  31. Data Frame Properties On-the-fly projection requires coordinate system definition (often stored in .prj file)

  32. Data Frame Properties • Map units can be set by user when coordinate system is not specified

  33. ArcToolbox System Tool Model Includes tools for manipulating spatial data Toolset Script

  34. Online Help Context Sensitive Help can be accessed with the “What’s This?” Button Access ArcGIS Desktop Help system under the Help menu

  35. Online Help ArcGIS Desktop Help is organized by topic and often by application

  36. Online Help Press the F1 key to access help about dialog box elements

  37. Online Help • ESRI user forums • http://support.esri.com/index.cfm?fa=forums.gateway
