unclassed choropleth map
An Unclassed Choropleth map is a map that doesn't have to classify the data displayed by using colors in proportion to the values of data. This map is based on the fertiity rates of Europe.

standardized choropleth map
Standarized choropleth maps gather information about a specific topic and its a type of thematic mapping that uses color to display the areas of information that they are talking about by using ranges and graduated color. They are also to interpret and understand. This image of a choropleth map lacks clearly being able to read because its taken from the air, but you can see the different colors that represent the type of land.

classed choropleth map
These are popular thematic maps because people understand them. A Classed Choropleth map is a map that classifies data. Colors are used to show the range of statistics of the variables. This classed choropleth map displays the homocide rate and compares the numbers through out the United States. The colors represent the numbers of deaths.
A Classed Choropleth map is a map that classifies data. Colors are used to show the range of statistics of the variables.
unstandardized choropleth maps
An Unstandardized Choropleth map is a map that have data plotted and presented in numerical values (raw values). Sometimes they will just give population numbers and not take into account the amount of land that those people are spread out on.

Nominal area choropleth map
Nominal Area Choropleth map is a map that classifies data into groups in no particular order they display information based on divisions that are already set, such as county lines. This map is displayed with color to show the information in the different areas of what they represent. In this particular case they stand for different types of metals and carbons.

range graded proportional circle map
A range graded proportional circle map is a proportional circle map where the circles size is dependent on the size of the range it is providing information for.This is a Menard graduated circle map. A Range Graded Proportional Circle Map also map that uses circles based on their size to correlate directly to the quantity for that data given in the symbol key.

Star plots allow you to compare different types of data for various experiments or design and they are a graphical way to display data in a 2-Dimensional chart. The radius of the star or design represents different characteristics. This particular star plot is a plot of MER IDD and other various designs. The different designs are compared in different categories, including mass, time (task completion), trajectory completion, collision, accuracy, link deflection, and actuator saturation.

Box plot
Box plots are used to examine one or more sets of data. It is graphically depicting groups of numerical data through five different quadrants. The image below shows two related boxplots on the same scale. The lower plot, "total", shows a simple boxplot with no outliers and the upper graph, "total adj", shows a set which includes an outlier.

Scatterplot
Scatter plots are mathematical diagrams that show the diagram for two different variables and one is on the X axis and the other is on the Y axis and they are usually drawn to send the trends between the two variables. This scatter plot represents the linear relationship between the two variables indicating the regression model.

cartographic animations
A cartographic animation map is could be used to represent spatial visualization and the amount of change over a period of time and is used on a computer or video to better display it. This cartographic animation is of two locations in the test area were chosen to be the endpoints for a hypothetical path around a mountain. This method presents route cost information in animations of cost surface realizations.

Choropleth maps
This is a cloropleth map. Cloropleth maps are thematic maps that display ares that are shaded or patterned in proportion to the measurement of the data. Two choropleth map examples are population density and per-capita income. They can also be used for indicating the differences in land use. This is a map of the Czech Republic.

Light detection and ranging
LIDAR (light detection and ranging) is an optical remote sensing technology that measures properties of scattered light to find range or other information of a distant target. The range to an object is measured through transition of a pulse and then to the detected reflection of signal. The military uses this technique. The above picture is of an urban area.

Isopleth map
This type of map is ideal for showing gradual change over space and avoids the abrupt changes which boundary lines produce on choropleth maps. Temperature, for example because temperature is continous yet does not change abruptly at any point. Relief maps should always be in isopleth form for this reason.

Thematic Map
Thematic mapping is also another way to display a trend in a particular area. The map above represents the new buisnesses in the United States. There are colors are to show the creation of buisnesses in the country. White is the lowest and dark red is the highest. I like these kind of maps because they are easy to interpret and are not as cluttured as some of the other maps we have learned about. http://www.infousagov.com/thematicmap.asp
Propaganda maps
This is an example of cartographic propaganda. This particular map is based around the Cold War. Propaganda maps can be a way to show the power of countries and the area they have control over. These are usually political and many were used during the time of the Nazis in the Soviet Union.http://limpingmessenger.wordpress.com/2009/11/09/songs-and-samizdat-made-the-wall-fall-europe-against-the-current-september-1989-revisited/
Infrared aerial photo
This is a picture of an infrared aerial photograph and it is taken of the Sacramento deep water channel. The color in the aerial photos usually represent the different land types and vegetation. The red is live vegetation and the blue grey is what kind of ground it is on and the moisture content. It can also be useful for analyzing water depth. This is also a part of the USGS.http://www.aerialarchives.com/infraredcolors.htm
Black and white aerial photo
This photo is used is a picture of L.A and is a black and white aerial photos also known as remote sensing and they are a type of photos that are taken from the air or a satellite image that shows the landform, its resource, and vegetation.The US Geological survey began using these. These infrared aerial photos can be colored or like the one above which is black and white and taken at high or low altitutes. http://www.lensculture.com/webloglc/mt_files/archives/2008/05/-from-the-series-oblivion.html
Dopplar radar
This dopplar radar map has a color scheme that makes it easy to visualize what the weather is like in the area shown. In this map there is more green, blue, and yellow and hardly any pink. There is a lot of rain. In some areas its light where as other areas its heavier. This map doesnt have any pink in it which means that there isnt any freezing going on. I think this is a good dopplar radar map because the color scheme helps me understand what the weather is like in other areas. http://backyard.weatherbug.com/profiles/blogs/choosing-the-best-doppler
Flow maps
Unlike dot distribution maps flow maps are clear and not cluttered. Cartographers use these to represent and display data such as the movement of an object from one area to another. A flow chart could be used when ahttp://graphics.stanford.edu/papers/flow_map_layout/naylzing data such as where the birds migrate to during the northern months due to climate change.
Mental Map
This is a mental map. I chose this one to be my example because when I think of mental maps I think of my third grade class when my friends and I would draw our treasure maps. Mental maps are a persons own perception of how they view the world. http://designrevival24.wordpress.com/2011/06/25/understanding-place-mental-mapping/
Dot distribution map
This dot distrubution map is representing the hispanic population in the Los Angelos. These kind of maps are uses a dot to symbol a trend in a certain area. They rely on visual scatter to show spatial pattern. Another way a dot distribution map could be useful for would be displaying the outbreak of a virus or sickness in a particular area.http://krygier.owu.edu/krygier_html/geog_353/geog_353_lo/geog_353_lo08.html
