CARTOGRAM MAPS


These particular maps may differ in their size when showing geographic area. Area and distance cartograms are the two different types of cartogram maps. Spatially these maps are distorted so that they can show the alternate variable information.

This particular map is showing us population.

WIND ROSE


A wind rose is more of a graphic insturment commonly used by meteorologists to give a compact display of how direction and wind speed are usually allocated at a particular location. This image depicts wind speed measured by knots. The various colors of speed are expalined in the map legend.

STAR PLOTS



Star plots show us multivariate observations with a subjective variables. Each observation is displayed by a star-shaped design with one ray for each variable. This image is the variable assignment for the featured starplot.

CONTOUR MAPS


Contour maps are created using contour lines. These maps take separate measurements, interject between them with the intent to create a grid that is uniformed. These measurements are then shown as lines of constant values. This map shows the high temperature predictions during June 27th. The legend shows the meaning for each color temp. of each state.

FLOW MAP


At some point in our lives, we have all used a type of flow map. Flow maps depict object movement from one place to another place. These maps are mostly done by hand and a good tool to use due to the fact that they merge edges with the reduction of of optical fill. This flow map is showing how quickly satellites would spread during the year 2006 across the US.

ISOLINE MAPS


There are several examples of Isolines maps, maps that have joint lines which all have same value points. These lines are also nonstop. Different examples of an isoline map would be a contour map and thematic map. This isoline map is of annual precipitation.

MENTAL MAP


Mental maps shows us inside the human mind, tracking the places that they have been visually. Each person has their own and no two maps are the same. This mental map is a little difficult to see, but it is of a center. It was drawn from a person's memory of what the area looks like.
