Univariate Choropleth Map

A univariate choropleth map, maps one specific variable and breaks the values up into color coded classes to portray the population or percentage in each area. In this map they are looking at the hispanic or latino population in Florida. Most of the hispanics live in South Florida and as you travel north the population gets less and less.

Sonar Map

Sonar Maps are used to show depths of water and can be used to show what is located on the bed of the body of water. This is a map of a lake and inside the contour lines they show the level of the water. You can see that it is almost a reverse cliff because if all of the contour lines were going up it would make a cliff, but because each circle goes deeper and deeper, there is no cliff. The deepest part of this lake is in toward the top of the map.

Mercator Projection

A mercator projection is a head on from the side projection of the blog. It would be as if you cut a slice down the middle of the globe from the north to the south pole and rolled the map out as if it were a cylinder. This is a mercator projection of the whole earth and you can see that it is a dead on view as if you are looking ath the globe from the side.

Continuously Variable Proportional Circle Map

This is a Continuously Variable proportional circle map. In this map the provide a key and estimate circles inbetween the key. No circle is the same size on this map unless they have the exaxt same value. This is opposite from the range graded proportional circle map becasue they have specific circle sized that represent a range. In this map you can see the mexican population is biggest in Texas, California, Nevada, and Arizona. That is becasue those are all the states on the Mexican border.

bivariate choropleth map

A bivariate Choropleth map shows two different sets of variables on the same choropleth map. In this map each color represents two different sets of numbers. For each color there is a smaller set of numbers which is the population of 1997 and a larger set of numbers which is the median value.

Resource Map

This resource map is a planimetric map that exposes where resources are on the land. These maps are helpful to lock at when you are lookign for a specific resource. Different pictures and the map legend are used to show where specfic resources are. There are lots of different available spots on this map for mining which is what is most likely done often on this land.

Star Plot

A star plot is used to show many observations on one chart. In this star plot they examined different types of cars and each piece of the star represents either price, mileage, repair record, head room, seat room, trunk space, weight, and length. From looking at the stars you can compare 16 different types of cars and decide which one sounds most appealing to you.
