Index value plot



A index value plot is a type of map that is a visualization map in which an index value is plotted on a line graph. This is used instead of an absolute value. These types of maps give caparison to to order the base of values off of. 

Lorenzo Curve Map



A Lorenzo Curve map is a graphical representation of the cumulative distribution function of the empirical probability distribution of wealth. This map is helpful for reprinting inequality on the wealth distribution in certain areas. The curve is a graph that shows the proportion of the distribution of inequality.

Bilateral graph



A bilateral graph map is a map that represents both positive and negative sets of data on one map. These sorts of maps allow a user to see more than one set of data at once. They can also be represented by line graphs, bar graph or some other kinds of maps as well. The above map shows control of assembly between master and slaves.

Nominal area choropleth map



A nominal area choropleth map is a thematic map that represents areal data. These types of maps use different colors or symbols to distinguish between certain areas and regions. Nominal data is represented meaning that there is no ranking to this information so there are usually many different colors used to represent cartographic information. These types of maps are great for comparing measurements or data between states or regions.

Unstandardized choropleth maps



Unstandardized choropleth maps are maps that contain data that have not been averaged even though it still allows comparison between variables. 

http://www.cdc.gov/pcd/issues/2007/oct/07_0091.htm

Standardized Choropleth Maps




Standardized choropleth maps are a way of representing the calculated population of an area per square mile. This is so the distributions can be compared. The shading on this map shows the relative distribution in each state.

Univariate choropleth maps




A univariate choropleth map is similar to a biunivariate map but only it displays data from only one variable. While doing this though it still falls under all the requirements of being a choropleth map even though it is much simpler than others. This map represents the estimated median household income in the United States.

Bivariate choropleth maps




Bivariate choropleth map shows two variables on a single map by combining two different sets of graphic symbols or colors. This is an important feature and technique in cartography. These types of maps are variations of simple choropleth maps that portrays two separate entities. simultaneously. The purpose of these maps are to find a simple method for accurately illustrating the relationship between two spatially distributed variables. This map is showing the percentage under the age of 18 years old.

Continuously variable proportional circle map






A continuous variable proportional circle map is similar to a dot distribution map. Continuous variable proportional circle maps show the distribution of a certain amount of variables and how they are proportioned through a land area.  This map uses different sized circles to represent American Indian Population by state in the year 1990.

Digital Elevation Model Map




A DEM map is a digital model or 3D  representation of a terrains surface to produce a terrain elevation diagnosis. A DEM can be represented as in raster or vector based TIN form. It is often a black and  white image that is hard to read but is effective at representing areas of interest in ArcGIS

Digital Line Graph Map



A DLG is a cartographic map feature represented in digital vector form that is usually disbursed by the USGS. These maps are distributed in different sized scales with up to nine different categories of features deepening on the scale.

Isopach



Isopach maps illustrate the thickness variations within a geological layer. They are contour lines of equal thickness over an area. 

http://en.wikipedia.org/wiki/Isopach_map
 

Isohyets




Isohyets are areas on a map representing points on a map with similar amounts of rainfall at a  given time.  This can help people who want to potentially visit a certain region to aid them in either avoiding these areas or showing them exactly where they want to be.

Isotachs



Isotachs are helpful in determining wind speeds on a map and in a certain region because they are lines on a map that represent wind speeds. These areas are usually areas of equal wind speeds that have been recorded over time. 

http://www4.ncsu.edu/~nwsfo/storage/cases/20030123/

Isobars





Isobars are lines on a map that connects points that have the same atmospheric pressures at a given time or period. These lines are helpful in determining weather patterns for a certain region.

Doppler Radar




A doppler radar is a special radar system that uses the doppler effect to function. This produces velocity data about objects at a distance. Pretty much, it beams a signal at an object and then listens for the frequency at which it returns that is altered due to the objects motion. This system can give incredibly accurate reads of where an object is and how fast its moving. Doppler radars are used in aviation,meteorology, and radiology along with many other things.

Black and White Aerial Photography






Aerial photography has proven to be extremely helpful to cartographers and planners. Through them they are able to take detailed measurements and then apply them to maps. Black and white maps where the first of their kind are still used to day because of the stark contrast that they implement. Aerial maps are a powerful tool in studying and understanding the surface of the Earth. 

Infrared Aerial Photos




Infrared photographs are used by using special film that captures parts of the light spectrum that is not entirely visible to the human eye. Infrared photography is a combination of wavelengths that gives scientists a better understanding of whats happening on the Earth's surface. Infrared technology can be useful in assessing the health of plants because depending on what color their leaves are will reflect different shades of light. Unlike water that absorbs all the infrared wavelengths and appears black on film. Another helpful quality to these types of photographs are the ability to penetrate atmospheric haze. This therefore results in clear and crisp images of a particular areas suffering from haze. In general, infrared aerial photographs make it easier to collect accurate satellite images and high altitude aerial photographs.

Cartographic animations






Animation in maps has been happening as old as maps themselves. This is because movement is apart of the environment. Animation in cartography is defined as a graphic art that occurs in time, animation is a dynamic visual statements that evolves through the change of the display. This sort of animation is not generally used though because it is expensive to make. There are mathematical computation software that crunches numbers to turn weather systems into moving maps though. It almost looks like what a Doppler radar maps put off only it is been computed by a machine.

Cartogram Maps





A cartogram is a map that illustrates some type of thematic mapping variable such as population or travel time. For these types of maps the geometry or space of the map is distorted in order to correctly depict the information that one is trying ti display. There are two main types of cartograms, area and distance cartograms.

Flow Maps





Flow maps are maps that represent a mix of maps and flow charts, hence the name. The show the movement of objects from one location to another. This particular flow map is showing Charles Minard's visualization of French wine imports around the world in 1864. As you can see from the map above, flow maps can be used to represent almost anything.

Choropleth Map



A choropleth map is a thematic map that represents a statistical variable on a map by using shaded or patterned areas. An example of what a map like this would be population density or per-capita income. The use of choropleth maps are a easy way to visualize how a measurement varies across a geographic area that shows variability of a region.

Dot distribution maps




Dot distribution maps aka dot density maps are maps that use a dot as a symbol to represent the presences of certain features. These sorts of maps rely on visual scatter of the dots to show a pattern. There are two different types of dot distribution maps: One to one and one to many.

Propaganda maps







Propaganda Maps are maps that are made out to be straight up falsified through cartographic maps, much like traditional propaganda. These sorts of maps can also be created with the goal of persuasion in mind. All maps are subjective and therefore can be manipulated. These maps can lie and can represent completely distorted views of reality.

Hypsometric maps






Hypsometric maps are maps that are related to using contour lines.  They can be used to depict ranges of elevation as bands of color, usually in a graduated scheme, or applied to contour lines themselves. Hypsometric tinting of maps and globes are often accompanied by a similar method of bathymetric tinting to convey depth of oceans.

PLSS Map



A PLSS map of Public Land Survey System is a way of describing and dividing land in the United States. The Bureau of Land Management is responsible for regulating the land in the US. All lands in the public domain are subject to division. This happens by a system of rectangular system of surveys that usually divides lands into 6-mile long townships which are then further divided into 1-mile long square sections. The PLSS is the standard for most land transfers and ownership in the US today.

Cadastral Map






Cadastral maps display the spatial descriptions of land-parcel boundaries that define the location, shape and size of land parcels within the context of a regional or national geodetic positioning system. They also contain a unique parcel identifier to establish the link to the land-ownership information. When maintained in a real-time manner, cadastral maps can serve as the base for a reliable property rights system. 

This Particular map that I have included is a hybrid of a cadastral map and a topographic map. All of the same characteristics stated above regard this hybrid map.

Thematic Map


This is a thematic map representing population density by state. Thematic maps are types of maps specially designed to show a particular theme connected with a specific geographical area. These types of maps can portray specific aspects of a city, state. region or continent. 


Topographic Map


This is a topographic map. Topographic maps are representations of a three dimensional surface on a flat piece of paper. The shaded relief portions on this maps are to represent elevation. Most maps are laid out in rectangular blocks with sides parallel to latitude and longitude lines. Topographic quadrangle maps west of the Mississippi River are laid out in township, range and section as well as latitude and longitude. Topographic maps can be helpful locating certain lines of an area. 


Planimetric Map of Tallahassee, FL



Planimetric maps are distinguished by being a "surface map" and most well recognized as street maps. The horizontal features are depicted and the vertical are not included in planimetric maps.This is a road map of Tallahassee, Florida and is a form of planimetric mapping because there are no contours or relief features. The map is purely two dimensional to give the reader a picture image of the location of each major road in the city of Tallahassee. In using a road map such as this one the reader does not need to know information such as defaults in the surface or elevations of land. The knowledge that is needed is the location of the placement of streets in order to get from place to place as well as a scale in order to estimate time of travel.
