Proportional Circle Map


Proportional Circle Map


Proportional Circle Maps are popular because circle scaling is less difficult than with other symbol forms and they are more visually stable, and so they result in images that cause little eye irritation to map readers.

Isoline Map


Isoline Map

Isolines are extremely important in weather mapping because they are easily understood and quickly demonstrate temperature differences on a map. Most often, red indicates the hottest areas, and blue represents cold areas.

Flow Map


Flow Map

Flow maps sequence thought processes. They can explain the order of events and identify relationships between the even stages.

Cartogram


Cartogram


This example of a cartogram is depicting the allotment of electoral votes in the US. Electoral votes are awarded to each state according to the size of the population. This example details that Wyoming, Montana, North Dakota, and Washington D.C. have the same land mass size although in reality the first 3 states are hundreds of times larger than D.C.

Statistical Map

LIDAR


LIDAR

LIDAR, which stands for Light Detection and Ranging, is a type of remote sensing technology that uses laser pulses and scattered light to measure distance and ranges of a distant object. In this example, LIDAR was used to display the aftermath of the September 11th attacks on the World Trade Center.

Isotach

An isotach map is a map whose line in a given surface connects points with equal wind speeds.

Isohyet

An isohyet map is one who's contour lines on a map connect areas of equal rainfall during a given time period or for a particular weather pattern, such as a thunderstorm.

Isopach

Isopach

An isopach map is a map that shows contour lines of equal thicknesses over a particular area.

Isopleth


Isopleth

An isopleth map is a map that generalizes and simplifies data with a continuous distribution, like elevations, pressures, and precipitation. Isopleths never cross or divide one another and always form enclosed circles.

DRG


DRG


A digital raster graphic (DRG) is a scanned image of a USGS topographic map. The scanned image includes all map collar information.

DLG


DLG

DLG stands for Digital Line Graph and is a form of digital map developed by the United States Geological Survey. It supplies digital information from topographical quadrangle maps.

DEM


DEM

Digital Elevation Models are data files containing information about the elevation of an area.

DOQQ


DOQQ

"DOQQs are color infrared images with one meter per pixel resolution. DOQQs are provided in the UTM coordinate system."

Continuously Variable Proportional Circle Map


Continuously Variable Proportional Circle Map

A continuously variable proportional circle map is a map that uses circle of representing different values to represent point data.

Range Graded Proportional Circle Map


Range Graded Proportional Circle Map

In this map, the cartographer applies a formula to control the area of circles and then applies precise expansion factors, creating proportional circle maps in which the circle area reflects the population of Mexicans in the Western US.

Classed Choropleth Map


Classed Choropleth Map

In this map, the 6 classes are distinguished by 6 colors. The proportions of males per 100 females are not exactly the same in every state that is the same color, but they can be attributed to the same class.

Unclassed Choropleth Maps


Unclasped Choropleth Maps


This type of choropleth map assigns shadings proportional to the data displayed so that the maps do not have to classify the data.

Bivariate Choropleth Map


Bivariate Choropleth Map

Bivariate maps map two variables using graduated color symbols.

Univariate Choropleth Maps


Univariate Choropleth Map

This choropleth map is using crime propensity by block to distinguish each class marking. It is univariate because each block is it's own isolated geographic area.

Standardized Choropleth Map


Standardized Choropleth Map

This Choropleth map is an example of a standardized choropleth map because it is demonstrating each pixelated unit, a certain area (in m, km, mi, etc.), as a function of the population interaction index. This is more accurate than a map according to political boundaries.

UNstandardized Choropleth Map


Unstandardized Choropleth Map

This is an example of an unstandardized choropleth map because it is describing the change in population for a state as a whole, while it is not clearly representing the change in each county. Shifts at more localized levels are not displayed which in fact may be more relevant to the data requested.

Nominal Area Choropleth Map

Nominal Area Choropleth Map

A nominal area choropleth map uses nominal data (such as % of population per square kilometer) and displays it on a map using specific colors or patterns to represent the differences in percentage. This example uses varying degrees of red tones to distinguish between high percentages and low percentages of hispanic populations in the United States.

Bilateral Graph

Bilateral Graph

A bilateral graph is an example of a visualizing map. Two related variables, in this graph, longer term mortgage assets, and construction and development loans are graphed according to time (year).

Lorenz Curve



Lorenz Curve

A Lorenz Curve is a probability curve. In this graph, it is demonstrating the unequal distribution of income. The farther it is from the line of equality, the more unevenly the % of income is distributed.

Index Value Plot


Index Value Plot

An index value plot shows the ratio of all items being compared against one another in a specific period of time. This particular example is comparing the genome maps of particular organisms.

Scatter Plot


Scatter Plot

This plot maps out a linear relationship between wives ages as a function of their husbands. This distribution shows that as a wife gets older, her husband does as well.

Population Profile



Population Profile

This population profile represents a city's current age distribution and the projected age distribution in 2026. It demonstrates it's current status and pending growth.

Climograph


Climograph

In a climograph, the bar graph represents precipitation over time, and the line represents the temperature. In this climograph, the months of June, July, August, and September in Memphis, TN had the highest temperatures as well as the most rain.

Wind Rose


Wind Rose

This wind rose is located in St. Peter's Square. This structure uses compass points (N, S, E, W, NE, etc.) to show wind directions. Each marker in the square labels the wind from that direction

Triangular Plot

A triangular plot graphically depicts the ratios of three variables as positions in an equilateral triangle. (definition)

This particular map is comparing 4 types of soils and the organisms living within them.

Histogram


Histogram


This histogram represents collected data in columns. The categories represent a continuous measure. In this example, it is age in years.

Box Plot


Box Plot

A box plot is a range of data, with the inside "box" containing the data information called the IQR and the lines extending from that box the most extreme values.

Stem and Leaf Plot


Stem and Leaf Plot


A stem and leaf plot is a way to organize random data. In this example, the data is organized in a tabular way, to make it easier to see relationships, how many "leafs" there are to the "stem" or number values in increments of 10.

Similarity Matrix


Similarity Matrix

This similarity matrix is cartographically representing the song "Hey, Jude" by The Beatles. Dark blue squares represent lines of similarity, or repeating parts. Google defines a similarity matrix as, "a matrix of scores which expresses the similarity between 2 data points."

Correlation Matrix


Correlation Matrix

This is a correlation matrix because it is estimating the relationship between multiple variables.

Star Plot



Star Plot

This star plot represents the position of the stars over Ireland. It is interesting to read in the article accompanying this map that the Monks of early Christianity realized the Earth was indeed round, and that the Earth had a gravitational "wobble"which explained the shift in positions of the stars.

Choropleth Map


Choropleth Map

This map shows the percent of people living in Florida who are of Hispanic decent by county. This map is 10 years old, and has some skips in the natural breaks, but is overall a decent representation of the greater Hispanic populations in FL.

Mental Map



Mental Map

This map represents a mental map of a child from Gaza. She is recalling from memory her home, friends, and an airplane. The placement of these features is important. She is orienting these pictures as they are in her life, and as she seems them . Her home and airplane are much bigger than she is, the plane is flying overhead, and there are clouds above the plane.
