Star plots
Star plots allow you to compare different types of data for various experiments or designs. The radius of the star or design represents different characteristics. This particular star plot is a plot of MER IDD and other various designs.

Similarity matrix
A similarity matrix is a matrix of scores which express the similarity between two data points. Similarity matrices are strongly related to their counterparts, distance matrices and substitution matrices.

Stem and leaf plot
Stem-and-leaf plots are a method for showing the frequency with which certain classes of values occur. You could make a frequency distribution table or a histogram for the values, or you can use a stem-and-leaf plot and let the numbers themselves to show pretty much the same information.

Box plot
A box plot or boxplot (also known as a box-and-whisker diagram or plot) is a convenient way of graphically depicting groups of numerical data through their five-number summaries (the smallest observation (sample minimum), lower quartile (Q1), median (Q2), upper quartile (Q3), and largest observation (sample maximum). A boxplot may also indicate which observations, if any, might be considered outliers.

Histogram
A histogram is a graphical display of tabulated frequencies, shown as bars. It shows what proportion of cases fall into each of several categories: it is a form of data binning. The categories are usually specified as non-overlapping intervals of some variable. The categories (bars) must be adjacent. The intervals (or bands, or bins) are generally of the same size.

Triangular Plot
A triangle plot is a barycentric plot on three variables which sum to a constant. It graphically depicts the ratios of the three variables as positions in an equilateral triangle

Windrose
A wind rose is a graphic tool used by meteorologists to give a succinct view of how wind speed and direction are typically distributed at a particular location. Historically, wind roses were predecessors of the compass rose on maps, as there was no differentiation between a cardinal direction and the wind which blew from such a direction.

Climograph
A climograph is a graphical depiction of the monthly precipitation and temperature conditions for a selected place. Precipitation is shown by the bar graph. A line graph depicts temperature.

Population profile
Scatterplot
A scatter plot is a type of display using Cartesian coordinates to display values for two variables for a set of data. The data is displayed as a collection of points, each having the value of one variable determining the position on the horizontal axis and the value of the other variable determining the position on the vertical axis.

Lorenz Curve
In economics, the Lorenz curve is a graphical representation of the cumulative distribution function of a probability distribution; it is a graph showing the proportion of the distribution assumed by the bottom y% of the values. It is often used to represent income distribution, where it shows for the bottom x% of households, what percentage y% of the total income they have.

Bivariate choropleth maps
A bivariate map displays two variables on a single map by combining two different sets of graphic symbols or colors. Bivariate mapping is an important technique in cartography. Given a set of geographic features, a bivariate map displays two variables on a single map by combining two different sets of graphic symbols. It is a variation of simple choropleth map that portrays two separate phenomena simultaneously.

Unclass Chorlopeth Map
This technique assigns shadings proportional to the data values so that these choropleth maps do not have to classify the data. This method of mapping has not been generally accepted because many cartographers claim that they lose the ability to direct the message of communication.

Range graded proportional circle map
Continuously variable proportional circle map
A continuously variable proportional circle map is a proportional circle map which utilizes circles to create point data. This relates the scales to the specific data. The circles are in proportion to the variable being measured.

DEM
A digital elevation model (DEM) is a digital representation of ground surface topography or terrain. It is also widely known as a digital terrain model (DTM). A DEM can be represented as a raster (a grid of squares) or as a triangular irregular network. DEMs are commonly built using remote sensing techniques, but they may also be built from land surveying. DEMs are used often in geographic information systems, and are the most common basis for digitally-produced relief maps.

DRG
A digital raster graphic (DRG) is a digital image resulting from scanning a paper USGS topographic map for use on a computer. DRGs created by USGS are typically scanned at 250 dpi and saved as a TIFF. The raster image usually includes the original border information, referred to as the "map collar". The map file is UTM projected and georeferenced to the surface of the earth. DRG's are regularly used in GIS applications.

Isopleth
An isopleth map generalizes and simplifies data with a continuous distribution. It shows the data as a third dimension on a map, thus isopleth maps are more common for mapping surface elevations, amounts of precipitation, atmospheric pressure, and numerous other measurements that can be viewed statistically as a third dimension.

Isopach
An isopach map is a map illustrating variation of thickness within a tabular unit or stratum. Isopachs are contour lines of equal thickness over an area. Isopach maps are utilized in stratigraphy, sedimentology, structural geology, petroleum geology and volcanology.

Isotachs
Isotachs are found on a weather map and are used to show different wind speeds. This map is of Mexico and the western United States. When the Isotach lines are close together, that is where the wind is the strongest.

Isobars
A line drawn on a weather map connecting points of equal pressure is called an isobar. The isobars are generated from mean sea level pressure reports and the pressure values are given in millibars.

LIDAR
LIDAR (Light Detection and Ranging) is an optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. The prevalent method to determine distance to an object or surface is to use laser pulses.

Doppler Radar
Doppler radar is radar that makes use of the doppler effect to produce data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the original signal has been altered by the object(s) that reflected it.

Infared Aerial Photo
Infrared aerial photography is a powerful tool. Not only can it be used to document changes to the environment, the health of forests, wetlands, bays and oceans, but it can also be used to document and monitor such items as damage to roofs, the tracking of dairy farm out flows, pinpointing the source of, and monitoring, insect or disease infested vineyards, or sites contaminated by toxic chemicals, and many more applications.

Statistical Map
Cartogram
A cartogram is a map in which some thematic mapping variable – such as travel time or GNP – is substituted for land area. The geometry or space of the map is distorted in order to convey the information of this alternate variable. There are two main types of cartograms: area and distance cartograms.

Choropleth Map
Choropleth are thematic maps based on predefined aerial units. Think of it as a multi-colored checkerboard map. Some maps, (ex. road maps), show many types of data while thematic maps are made to show only one specific set of data. Because each group of data is organized as a ratio value, (a zero value for comparison is present), we use what a graded color series to show least intensity to most intense (shown using a light to dark color pattern).

Planimetric Map
Planimetric maps are digital, graphic maps that portray the horizontal position of planimetric features using lines and symbols. Ground control is set for this product. Aerotriangulation is performed to determine the position and orientation of the camera for each exposure so planimetric features are shown in their true relative coordinate position.
