  10. Population under 14 by NeighborhoodCity of Pittsburgh Data obtained from U.S Census, 2000

  11. Injury Rate by NeighborhoodCity of Pittsburgh Data obtained from Children’s Hospital of Pittsburgh, 2000-2005

  12. Map Layouts

  13. Map Layouts • Includes all of the elements of a stand alone map • Make the map the largest and most prominent element of the layout • Put a rectangular boundary around the map (called a neat line by cartographers) to help draw attention to it as the central element • Include a map title • The title needs to include information minimally answering the three questions what, where, and when.

  14. Map Layouts (Continued) • Include a legend for symbols placed in the lower-right or left of the layout • No need to label it Legend. Everyone will know what it is (this eliminates “chart junk”) • Include data sources • Ensure legibility • Include a graphic map scale if your audience is not familiar with the area shown • Do not include a north arrow unless the top of your map is not north

  15. Map Layouts (Continued) • Occasionally include other components as needed such as a data table listing, a frequency bar chart for the attribute of a choropleth map, or a photograph

  16. ArcView Layouts

  17. Other Map Elements Neatline, Scale, Additional Text, Photos

  18. Example of a bad map...

  19. A better map…

  20. Map Scales

  21. Dimensionless Map Scales • ratio that relates a unit of measure on a map to some number of the same units of measure on the earth's surface • 1:25,000 • tells us that 1 unit of measure = 25,000 of the same units on the earth's surface • 1” on the map = 25,000 inches on the earth's surface • one meter or one yard or one kilometer or one mile would represent 25,000 meters or yards or kilometers or miles, respectively, on the earth's surface.

  22. Small Scale Map Large Scale Map Large and Small Scale Maps 1:5,000 is largescale 1:50,000,000 is small scale

  23. Commonly Used Map Scales http://id.water.usgs.gov/reference/map_scales.html

  24. USGS Scales http://www.carolinamapdistributors.com/products/topo/mapscales.htm

  25. Map Units Feet or meter is the map unit for many local government GIS applications

  26. Map Units Inch is the map unit for CAD applications

  27. Scale 1:100,000 Scale

  28. Scale 1:24,000

  29. Scale 1:10,000

  30. Scale 1:2,000

  31. Multiple Maps, Reports, and Graphs

  32. Multiple Maps – Comparing Data

  33. Reports and Graphs

  34. Reports on a Layout Select records to include

  35. Reports on a Layout Generate a report

  36. Reports on a Layout Add report to the layout

  37. Graphs on a Layout Select records to include Create a graph and include on layout

  38. Importing Charts Create graph in excel Copy and Paste object to layout

  39. Exporting Maps

  40. Exporting Maps Export Images

  41. Exporting Maps Export Images
