3 1 Political and Locator Maps Arizona Counties Mohave Coconino Navajo Apache Yavapai La Paz Gila Maricopa Greenlee Yuma Pinal Graham Pima ² Santa Cruz Cochise Miles Map Projection: UTM, Zone 12 Feb 1, 2016 Figure 1: A map of Arizona counties. In this lab, we added map layers to a map project in ArcMap. Then we changed the data layer symbol properties, created a map layout, created a locator (inset) map. Finally, we added a title, scale bar, and north arrow. 3

4 2 Base Maps and Digitizing Digitizing in ArcMap. Legend Trees Streams Structures Feb Feet Figure 2: Digitized map In this lab, we digitized an air photo of a neighborhood in southeast Macomb, Illinois. We created a polygon shapefile for Structures, a polyline shapefile for Streams, and a point shapefile called trees. Using these polygons, polylines, and points, we digitized the map. 4

5 3 Data Entry Report Figure 3: Data entry for Wyoming counties In this lab, we worked with data for thematic mapping that came from a variety of sources. In particular, we added a field to an attribute table, sort records in an attribute table, and joined data tables. Finally, we created a table report. 5

6 4 Choropleth Mapping European Nations Cell Phone Use in 2006 Subscriptions per 100 people Data for Albania, Andorra, Italy, Liechtenstein, Monaco, Netherlands, Sweden are from 2005 February 29, 2016 Figure 4: Choropleth map showing the cell phone use in European nations in 2006 In this lab we visualized the cell phone use in European nations with a choropleth map. We classified the data (subscription per 100 people) in five classes using Natural Breaks (Jenks). 6

7 5 Dot Density Mapping Contiguous United States Sheep and Lamb Based on 2002 Data Legend ± States Agriculture County Agriculture 1 Dot = 1,000 SheepLambs One Dot Represents 1000 Sheep and Lambs Dot placement is random using county-level data March 7, 2016 Data Source: USDA National Agricultural Statistics Service, 2002 Figure 5: Dot density map showing the number of sheep and lamb in USA In this lab we visualized the number of sheeps and lambs in the US using a dot density map. 7

8 6 Graduated and Proportional Symbol Maps Storm categories Hurricane Katrina and Hurricane Emily Tropical Depression 110 0'0"W 100 0'0"W 90 0'0"W 80 0'0"W 70 0'0"W 60 0'0"W Tropical Storm Canada Hurricane, Category 1 Hurricane, Category '0"N 40 0'0"N Hurricane, Category 3 United States Hurricane, Category 4 Bermuda 30 0'0"N 30 0'0"N Hurricane, Category 5 1,000 Miles 20 0'0"N HURRICANE KATRINA Formed August 23, 2005 Dissipated August 31, 2005 Highest wind speed: 175 mph (152 kts) Fatalities: 1,836 Damage: $81.2 billion The costliest Atlantic Hurricane in history The sixth strongest Atlantic hurricane on record The third strongest hurricane to make landfall in the United States HURRICANE EMILY 10 0'0"N Formed July 10, 2005 Dissipated July 21, 2005 Highest wind speed: 160 mph (139 kts) Fatalities: 15 Damage: $550 million The strongest hurricane ever to form before August The earliest Category 5 hurricane ever recorded in the Atlantic Basin Mexico Hurricane Katrina Cuba 20 0'0"N Cayman Is. HaitiDominican Republic Jamaica Puerto RicoAnguilla Belize Guatemala Guadeloupe Honduras Martinique El Salvador Nicaragua Hurricane Emily Barbados Aruba Grenada Costa Rica Panama The Bahamas Turks & Caicos Is. Colombia Trinidad & Tobago Venezuela Guyana 10 0'0"N March 21, '0" Ecuador Brazil 0 0'0" 110 0'0"W 100 0'0"W 90 0'0"W 80 0'0"W 70 0'0"W 60 0'0"W Figure 6: Graduate symbol map showing the path and intensity of two hurricanes The purpose of this experiment was to demonstrate the path and intensity of two notable hurricanes Katrina and Emily. The size and color represent the intensity of the hurricane. The duration of the hurricanes, damages cost by them are given in the legend. 8

9 Number of Farms in Texas Number of Farms ,000 March 21, 2016 Figure 7: Proportional symbol map showing number of farms in Texas. In this lab we visualized the number of farms in Texas using a proportional symbol map. The legend on the left indicates that the larger the size of the dot, the higher the number of farms. 9

10 7 Flow Maps Flow Map for Flights for Boise, Jackson and Syracuse in 2007 Reno San Francisco Seattle Portland o Los Angeles San Diego Spokane Boise Las Vegas Salt Lake City Phoenix Denver Dallas Minneapolis o Detroit Chicago Memphis Cleveland Jackson o Cincinnati Atlanta Charlotte Syracuse New York Philadelphia Baltimore Washington Flights 100 Ü 500 1,000 Data source: Federal Aviation Administration Houston ,040 Miles Orlando March 28, 2016 Figure 8: Flow map for 2007 flights. The purpose of the lab was to show the routes of flights in three airports using a flow map. 10
