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, however, 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.

Isopleths
Isopleths , or contour line, is a feature of meteorological charts, connecting points which have an equal value of some variable at a given time and spatial area. The particular variables shown on a given chart may include values such as pressure, temperature, wind speed, etc. They are used to assist in visualizing the general features of a meteorological "field".

Lorenz curve
Triangular plot
A ternary plot, ternary graph, triangle plot, simplex plot, or de Finetti diagram 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. It is used in petrology, mineralogy, metallurgy, and other physical sciences to show the compositions of systems composed of three species. In population genetics, it is often called a de Finetti diagram.
http://www.tfhrc.gov/pavement/pubs/03060/appa.htmA parallel coordinate graph is used to plot large multivariate datasets. Each variable in the data plot is represented as its own Y Axis on the graph. A maximum point for each Y axis is selected, and they are scaled relatively to each other so that each variable takes up the same area in the graph space.

Box plot
Box plot: s a convenient way of graphically depicting groups of numerical data through their five-number summaries (the smallest observation, lower quartile (Q1), median (Q2), upper quartile (Q3), and largest observation). A boxplot may also indicate which observations, if any, might be considered outliers. The boxplot was invented in 1977 by the American statistician John Tukey.

Stem and leaf plot
A stemplot (or stem-and-leaf plot), in statistics, is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution. They evolved from Arthur Bowley's work in the early 1900s, and are useful tools in exploratory data analysis.http://math.arizona.edu/~cossey/statistics
Star plot
The star plot or Irregular polygon, or polar chart is a graphical method of displaying multivariate data. Each star represents a single observation. Starplots allow you to compare multiple variables for each observation. Starplots allows for easy visualization of many variables. This illustrates the use of light hydrocarbon ratios to assess oil similarities or differences, which is especially important when dealing with condensates (after Halpern, 1995).
Windrose
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. This is a plot or Fresno, ca.
Climograph
Climograph: A graph of monthly average temperature plotted against average humidity. The monthly points are joined by a line. The shape and location of line thus drawn indicates the nature of climate in terms of heat and humidity.

Scatterplot
Scatterplot is a type of display using Cartesian coordinates to display values for two variables for a set of data. The above shows the amount and legnht of each eruptions at Old Faithful.
Bilateral graph
Continuously variable proportional circle map
Isotachs: A line along which the speed of the wind is constant. Isotachs are customarily represented on surfaces of constant elevation or atmospheric pressure, or in vertical cross sections.
Doppler radar: A radar system used to measure the relative velocity of the system and the radar target. The operation of these systems is based on the fact that the Doppler frequency shift in the target echo is proportional to the radial component of target velocity. This type of imaging is seen quite often in Florida during hurricane season. The above image is of Hurricane Frances as it passed through South Florida.

LIDAR
LIDAR: (Laser Radar) Lidar systems employ intense pulses of light, typically generated by lasers, and large telescopes and sensitive optical detectors to receive the reflected pulses. A method of detecting distant objects and determining their position, velocity, or other characteristics by analysis of pulsed laser light reflected from their surfaces.

Black and white aerial photo
Infrared aerial photo can 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. This photo shows ground zero days after the drastic attack.
Cartograms: Broadly defined as a map using statistical symbols, a more specialist usage defines a cartogram as a type of map transformation based on a scale other than a true scale. For example, a voting map of Britain may show the size of counties in relation to the numbers of voters in each electoral unit, or an economic cartogram of the world may show countries drawn in proportion to their per capita GNP. This map shows the countries that mostly contribute to global warming.
Flow maps in cartography are a mix of maps and flow charts, that show the movement of objects from one location to another, such as the number of people in a migration, the amount of goods being traded, or the number of packets in a network.[1] One of the most common examples are the maps on airplanes showing where the airline travels to and from. This map shows the spread of a Christianity.
Isoline maps: A line on a map, chart, or graph connecting points of equal value. Also called isogram. Map with continuous lines joining points of the same value. Examples would be equal altitude (contour lines), temperature (isotherms), barometric pressure (isobars), wind speed (isotachs), wind direction (isogon), wind shear (isoshear), etc. Isoline mapping is used to interpret the information on some thematic maps.
Proportional circle maps
Proprganda maps used to cause propoganda, just as it is named for. this map is of Albania. "Albanians were Brainwashed in the communist era that they were Illyrians in a way that included Thracians,Greeks(Macedons,Epirotes & others) into one thing, Albanians.This happened to justify territorial claims against neigbouring states and it continues to this day creating problems in the Balkans."
The Public Land Survey System (PLSS) is a method used in the United States to survey and identify land parcels, particularly for titles and deeds of rural, wild or undeveloped land.

Cadastral Map: A legal map for recording ownership of property. The map describes boundaries and ownership.Example: Tax assessors in some jurisdictions use a cadastral map to be certain that no property escapes taxation. These type of maps are used quite often with the property appraisers in Florida counties.

Planimetric map: A map indicating only the horizontal positions of features, without regard to elevation, in contrast with a topographic map, which indicates both horizontal and vertical positions. Also known as line map.
