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 50 25 0 50 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
2 Base Maps and Digitizing Digitizing in ArcMap. Legend Trees Streams Structures Feb 8 0 2550 100 150 200 250 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
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
4 Choropleth Mapping European Nations Cell Phone Use in 2006 Subscriptions per 100 people 0.00-42.27 42.28-68.74 68.75-100.46 100.47-114.51 114.52-146.87 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
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

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
Number of Farms in Texas Number of Farms 10 100 1,000 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
