An introductory tutorial for Esri's ArcGIS version 10.1. This tutorial covers some basic concepts and tasks.

Published in: Technology

Introduction to ArcGIS

  1. 1. Intro to ArcGIS Kate Dougherty, Geosciences & Maps LibrarianTutorial created for version 10.1 in February 2013
  2. 2. Overview• What is GIS? • Select features by• Common uses attribute• Software • Select features by• Interface & navigation location• Adding layers • Buffer features tool• Customizing & • Layout view displaying layers • Datums & projections • File management • Data sources
  3. 3. What is GIS?• Geographic Information Systems (GIS) is a computer-based methodology for collecting, managing, analyzing, modeling, and presenting geographic or spatial data.• Allows you to overlay datasets and query them in terms of their spatial relation to each other
  4. 4. Two Types of Spatial Data• Raster - continuous data – E.G., air photos, scanned maps, elevation layers – Most remote sensing data is raster data• Vector - discrete features – A layer comprised of individual points, lines or polygons (e.g., roads or states) – This presentation focuses on vector data
  5. 5. Common Uses• Analyzing potential environmental hazards• Emergency services planning and routing• Siting new facilities: – wind farms – power plants – vineyards• Identifying food deserts in urban areas• Much more!
  6. 6. Esri• Environmental Systems Research Institute• ESRI is now Esri• Industry leader for GIS software• Program is ArcGIS/ArcMap – Now up to version 10.1. – (This presentation done with V. 10)
  7. 7. Table ofcontents that The “data frame” that displays the spatial data.shows thedoc’s layers.
  8. 8. IdentifyGo to full Go to Go to Select featuremap previous next featuresextent extent extent (by hand) Select elements Clear (to move selected or edit) features Add data
  9. 9. Project:Identify Washington County Parcels Near Perennial Streams
  10. 10. Add Layers• States (Census Bureau)• Counties (Census Bureau)• Hydrography (Area - National Hydrography Dataset)• Parcels (Washington County – Wash_Co_Data_Month_Year.zip)• Public lands (GeoStor)
  11. 11. Click to add data
  12. 12. Coordinate Systems• All your layers may not necessarily use the same coordinate system. – OK to draw and display – Not OK for detailed analysis (need to reproject layers – advanced step)• Data frame will use the coordinate system of the first layer that’s added – (displays feet, meters, or decimal degrees/lat/long of cursor location in bottom-right corner, depending on coordinate system)
  13. 13. View With All Layers Added
  14. 14. Zoomed to Washington County
  15. 15. Rename States LayerState layerrenamed
  16. 16. Open the Attribute Table
  17. 17. Customizing LayersSelect by Attribute Tool
  18. 18. Selection is Highlighted
  19. 19. New Layer is Added to Map
  20. 20. Arkansas Only Remaining State
  21. 21. Changing the Display of Layers• Change symbology/colors• Turn individual layers on or off• Change the display order – Layers on map display according to their order in the table of contents – Top layers may hide features in layers under them – Click & drag a layer in the table of contents to change its display order on the map
  22. 22. Change the Display Order
  23. 23. Change Symbology of Layers
  24. 24. Change Color of Streams
  25. 25. New Symbologies Displayed
  26. 26. Clip Streams to Washington County Clip Tool
  27. 27. Access Clip in Geoprocessing Menu
  28. 28. Clip Tool Dialog Box
  29. 29. Clip Tool Progress Indicator
  30. 30. Clip Completed Indicator
  31. 31. Change Symbology of New Clipped Hydro Layer
  32. 32. New Clipped File Looks Great!
  33. 33. Analysis• We will find parcels that: – Contain perennial streams And note their status in the parcel layer’s attribute table.
  34. 34. Add New Columns to Attribute Table
  35. 35. Field TypesWhole Numbers Decimals• Short Integer • Double (integers from -32,768 (up to 6 decimal places) to 32,767) • Float• Long Integer (unlimited # of decimal (integers from - places) 2,147,483,648 to 2,147,483,647)
  36. 36. Task: Select Parcels with a Perennial Stream
  37. 37. View Selected in Attribute Table
  38. 38. View Selected Records Only
  39. 39. Task: Select Parcels in a “flood Zone”Within a Distance of Perennial Streams• Use the buffer tool to draw a “buffer zone” around specified features
  40. 40. Manage Files with ArcCatalog• File manager for files used in ArcMap• Best to manage moving pieces this way, instead of Windows Explorer
  41. 41. ArcCatalog Window
  42. 42. Use ArcCatalog to View Metadata
  43. 43. Share Maps and Layers with Packages• Package up all the information used to create a layer or map document for easy sharing by email, a shared drive on the LAN, etc.• Right-click a layer in the TOC and select “Create Layer Package”
  44. 44. Share a Map Package• To package up an entire map document for sharing, use File | Create Map Package
  45. 45. ArcMap will force you to create some limited metadata before creating asharable package. Click OK.
  46. 46. Creating Packages• Save the package as a file and share as you usually would• You must “validate” your package before saving – Detects any errors that would impede sharing
  47. 47. Validation• Any errors need to be corrected. Click on any error messages to see a help document.• Warnings are warnings only – can go ahead and publish.• If no problems, the share button will become active.
  48. 48. What Else Can You Do with GIS?• Join stats based on • Analyze viewsheds and geography (i.e., states) shadows to a states GIS layer and view the data spatially • Use web map services – Excel, CSV, text formats for mashups in your own applications• Create/digitize your own data • Much more!• import GPS data
  49. 49. GIS Software at University of Arkansas• Reference desk machine (version 10.1)• Campus-wide license – administered by the Center for Advanced Spatial Technologies (CAST)• Free software
  50. 50. Sources of GIS Data• Search for selected base layers (reference maps) from right within the application• GeoStor (Arkansas state portal)• geo.data.gov (federal portal)• National Map (USGS)• TIGER/Census Shapefiles (reference layers – boundaries, roads)
  51. 51. LibGuide• The Maps, GIS and Remote Sensing LibGuide can point you to: – Information on how to get Esri software through the campus license – Resources for learning GIS – Sources of GIS data (spatial and attribute)
  52. 52. Good luck! Thank you!
