Choropleth Map 
Choropleth map visually shows the variety of colors in shaded or patterned differences on the map that is correlated with measurement and variability across the specific geographic region. This map of Thailand depicts the Royal Thai Army Inductees who have been tested positive of HIV/AIDS from 1991-1993. Each color represents a different percentage of Thai Army Inductees in that particular region who have been tested positive for HIV/ AIDS.  We can figure out which region tested positive for the largest amount of Thai Army Inductees by looking at this map.


                                                Isarithmic Map

The isarithmic map show allows us to see the weather and precipitation value in a smooth contour map or a three-dimensional map. They show patterns of different temperatures across that region. By having multiple isarithmic maps of that region, we can estimate the temperatures, how much precipitation it receives annually, and where are the regions that are at risk for droughts. It helps us be better prepared incase there is flooding, severe drought, or winter storms.  This map shows the state of Georgia and its average annual precipitation in different regions within the state.


Dot Density Map


The dot density map shows the presence of a theme and display a spatial pattern across the map. The dots can represent one unit or several, depending on what is shown on the map. In this map, we can see the spatial concentration of poverty and any outliers that might be present by different colors that are represented. From this map, it is safe to assume that the South region of the United States has a high percentage of poverty, with some outliers with some low poverty regions spattered across that  region. 


Proportional Map 


Proportional map shows us the relative proportion across the the region in each cities by using large circles (squares and other geometrical shapes are acceptable) as their symbols. Specifically, this map shows U.S Energy Consumption in 1999 by placing small to large circles in each state.

Environmental Sensitivity Map


The environmental sensitivity map provide an clear understanding of coastal resources that are at risk if an oil spill occurred.  We're talking about resources such as; biological, sensitive shorelines, and human-use resources. This map will show what animals would be affected, what type of vegetation life would be destroyed, and how bad the spill would affect the beaches and parks. With this map, responders are better prepared to deal with an emergency and send out proper resources to each area that are being affected.
