Between 1965 and 1975, the United States and its allies dropped over 7.5 million tons of bombs on Vietnam, Laos, and Cambodia. In December 2016, the Department of Defense released digital records of bombing missions carried out during the Vietnam War. Because the records include the geographic coordinates of most strikes, they can be spatially visualized by the public for the first time—as long as somebody maps them.
In these lessons, your goal is to create a visually-striking, information-dense, print-ready map that will clearly convey the Vietnam War bombing missions that have available geographic data. First, you'll use a CSV file to create a one-to-one dot density map of every bombing mission during the Vietnam War—over a million individual points. Then, you'll search ArcGIS Living Atlas of the World for appropriate reference data and symbolize it appropriately. To enhance your map with more information, you'll also create a time series chart to illustrate the temporal distribution of missions over the course of the war. Additionally, you'll create an inset map that emphasizes bombing patterns and density with hexagon bins. Lastly, you'll arrange your maps and charts in a print layout and add text annotations to provide historical context and highlight areas of interest. Your final map will look good enough for a professional magazine and inform users about the Vietnam War.
