Abstract or Description

This map shows the distribution of cell phone towers across the state of Maine, as well the service areas that they serve. This map was created using an elevation map as a base map. On top of this map is a hillshade file that accentuates the perception of height in the mountains. On top of these layers are vector files showing the location of each cell phone tower in Maine, along with the corresponding service area. I found this map to be particularly interesting because it is able to show population density in an indirect way. Additionally, it highlights how difficult it is to have cell phone coverage in the mountainous central and western parts of the state. This map is projected in NAD1983 UTM Zone 19N.
