Stem and Leaf Plot

The plot above is an example of a steam and leaf plot. It is very useful and displaying larger data sets in a simplistic form to view a wide range of variable at one time. The numbers to the right of the column are the first digits of the data and the numbers to the right will be placed on the end to obtain the value. For example in column 14 it would go as 144, 147 and 148.Link to map

Box Plot

The plot above is a good example of a box plot. A box blot has three areas that must be paid attention to in order to be able to successfully read them. There are three lines in a box plot that represent values the one on the far left, in the middle and on the far right. The one on the left shows the minimum value for the particular category given the one in the middle the median and the one on the right shows the maximum value. Link to map

Histogram

A histogram like the one above is a frequency distribution. It plots data that fall into various categories. Histograms are very useful when looking at data like the one displayed in this graph I believe where scores on an exam or something of the like are plotted in relationship to how frequently they occurred from the chosen sample size. Link to map

Parallel Coordinate Graph

This is an example of a parallel coordinate graph. These graphs are very useful when trying to display and understand a numerous amount of variables. Link to map

Triangular Plot

A triangular plot displays the values of three variables within the confines of a equilateral triangle. This is an example of that practice being used.Link to map

Windrose

A windrose like the one above helps meteorologists determine the wind direction and wind speed. Link to map

Climograph

A climograph is a graph that shows temperature averages and the amount of precipitation that has fallen in an area. The climograph above depicts this information for Iquitos, Peru.Link to map

Population Profile

A population profile is a graph that shows how many people belong to a particular age group. The population profile above is hard to read but the left column represents age groups and the bottom column represents percentage of population. Furthermore the lighter blue represents the female population while the darker blue represents the male population. This chart could support studies that have shown that on average women out live men.Link to map

Scatterplots

Scatterplots are a bivariate representation on a graph that shows to variables being plotted and gives there values and their correlation to one another. This is an example of a scatterplot with a very high correlation. The viewer can tell because of how close the dots are on the plot. The closer together the dots are the higher the correlation and the further away they are grouped that represents a lower correlation.Link to map

Index Value Plot

An index value plot like the one above is a graph that plots values agianst an absolute value. The index plot above shows a plot of the streamflow of one day compared to the historical streamflow for this particluar stream which I was unable to find the name for. Link to map

Accumulative Line Graph

An accumulative line graph is a is a graph that shows the distribution of a variable which is then compared to an independent variable. In other words the Lorenz curve is compared to the line of equality.Link to map

Bilateral Graph

A Bilateral Graph show to variables on a map. Usually in graph form like the bar graph above that is showing trade with CIS region including exports, imports and also they included the total trade with this graph. This is not necessary for a graph to classified as a bilateral graph. Link to map

Nominal Area Choropleth Map

This type of choropleth map is known as a nominal choropleth map. It displays variables and the data they represent nominally. This is shown by using different colors to distinguish different categories. The map above is Hispanic Population Density per square mile.Link to map

Unstandardized Choropleth Maps

Unstandardized Choropleth maps are the opposite of standardized choropleth maps. They do not standardized the variables and it makes the data presented is in a more general form Link to map

Standardized Choropleth Maps

Standardized Choropleth maps are choropleth maps that the variable is standardized to make the map easier for the viewer to read. Which makes the map less distorted.Link to map

Univariate Choropleth Maps

Univariate Choropleth maps only have one variable to be analyzed. In this map the key which will be listed below is of the percentage of Europeans by census area.Link to map Choropleth map of percent of Europeans by census area, Dark Blue = 1 -10%, Light Blue = 10 – 50%, Yellow = 50 – 90%, Orange = 90 – 99%, and Red > 99%

Bivariate Choropleth Maps

With bivariate choropleth maps there are now to variables to analyze. Usually with these types of maps they are trying to show some kind of correlation between the two variables. For example, two examples could be the correlation between chewing gum and cavities. This map is difficult to read but it is a bivariate choropleth map of Europe.Link to map

Unclassed Choropleth Maps

Unclassed Choropleth maps like the one above hardly ever use numbers in the legend just different colors and shades of those colors to represent data as shown in the map above. This map is good to give the viewer a general since of the data given it would not be a good map for someone who wanted to see the actual numbers of the data retrieved which in this case would be yes and no votes.Link to map

Range Graded Proportional Circle Map

Range Graded Proportional Circle maps like the one above use a more pronounced difference between the circles to make it easy for the viewer to clearly distinguish between different categories of information presented. An example of this shown very clearly in the map above.Link to map

Continuously Variable Proportional Circle Map

This is an example of continuously variable proportional circle map which is very similar to a proportional circle map expect in this case we have another variable involved with the values that the circles represent. There is more data to analyze in continuously variable proportional circle map than there is in a proportional circle map.Link to map

Classed choropleth maps

The map above is an example of a classed choropleth map of east Africa. According to our notes classed chloropleth maps often display data for states, counties, etc. is combined into a smaller number of groups and portrayed in intervals. I think the map of above is a good representation of this defention.Link to map

DOQQ

A DOQQ map like the one above is an aerial photo that has the distortion taken out through a techinque called orthorectification which allow the once aerial photo to be viewed as a map. The DOQQ above is of lake named Lake Travis in Texas.Link to map

DEM

The map above is an example of a DEM map or digital elevation model. These map display changes in elevation. Futhermore, according to our notes DEM is a digital file cosisting of terrain elevations for ground positions at regularly spaced horizontal intervals.Link to map

DLG Maps

The map above is an example of DLG map or Digital Line Graph. According to our notes DLGs contain a wide variety of information such as boundaries, roads and utility lines. Also from our notes DLG is digital vector data the data about map features are stored as lines, points and areas.Link to map

DRG Map

DRG maps or DigitalRraster Graphics are scans of USGS maps and are turned into digital maps. This is an example of DRG map of a portion of Utah.Link to map

Isopleths

An Isopleth map like the one above is a map that contain lines that connect anything of equal value. The map above the lines are connecting snowfall amounts. Another example of an isopleth map are topographic maps that use contour lines as mentioned in previous posts. Also isobars, isopach and isohyets are all examples of an Isopleth map.Link to map

Isopach

Like the last couple posts isopach maps use contour lines to display data on a map. In this case isopach lines are used to indicate differing rock thickness. The map above the contour lines are representing isopach which are the red dotted lines and are giving rock thickness for a reservoir.Link to map

Isohyets

Isohyet maps are yet another way of using lines on a map to represent data. In this case isohyets are used to show the amount of rainfall in a given period of time. This is map of west Africa and the amount of rainfall is given in millimeters. Link to map

Isotachs

Isotach maps are similar to Isobar maps expect the lines used to connect change in meaning from atmospheric pressures to wind speeds. Link to map

Isobars

This is an isobar map and on the map are lines connecting equal atmospheric pressures that are called isobars.Link to map

Cartographic Animations

This is a good example of a cartographic animation which has most if not all of the characteristics of a cartographic animation. One of those characteristics is having animation on a map. This would classify as a map of southern Florida and even though this is just a picture this would be able to be animated and show one what the track of this Hurricane had done in the past and what it is predicted to do in the future and obviously where it is at present time.

Statistical Maps

Statistical maps can be a very broad range of maps. It is a map that displays statistical data by displaying it on a map. The map above would classify as a statistical map because it shows the statistics on places in the world and how well connected to the Internet they are if they are connected to it at all and this information is displayed in a map.

http://www.google.com/imgres?q=Statistical+maps&hl=en&sa=G&biw=1366&bih=532&gbv=2&tbm=isch&tbnid=8zkjRi3C-jMGjM:&imgrefurl=http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/census.html&docid=EboCysSAvh1o7M&imgurl=http://personalpages.manchester.ac.uk/staff/m.dodge/cybergeography/atlas/landweber_version_16.gif&w=719&h=503&ei=yJLCTsWQDoLctwea46H-BQ&zoom=1&iact=hc&vpx=610&vpy=162&dur=3931&hovh=188&hovw=269&tx=48&ty=142&sig=107395654614239701683&page=1&tbnh=158&tbnw=226&start=0&ndsp=10&ved=1t:429,r:2,s:0

Cartograms

Cartograms are maps that change or distort geographic properties to relate with statistical data or populations. In the Cartogram above you can see that the true geography has been distorted to represent the percentages of endangered species around the world.

Flow Maps

Flow maps show movement of data or people from one area to another. The flow map above shows the immigration of people to the U.S. from different countries and how they compare to one another numerically.

Isoline Maps

Isoline maps are maps that use continuous lines that connect data with equal value. The lines can be called isolines or contour lines.
http://www.google.com/imgres?q=%22Isoline+maps%22&hl=en&gbv=2&biw=1366&bih=532&tbm=isch&tbnid=htbwrmZw7kX_TM:&imgrefurl=http://giscommons.org/%3Fpage_id%3D18&docid=pA982qCYSbAw_M&imgurl=http://giscommons.org/files/2009/08/6.41.gif&w=406&h=276&ei=PIjCTsCcLce2tgfEo82pDQ&zoom=1&iact=hc&vpx=511&vpy=243&dur=94&hovh=185&hovw=272&tx=174&ty=96&sig=107395654614239701683&page=2&tbnh=122&tbnw=180&start=12&ndsp=12&ved=1t:429,r:2,s:12

Proportional Circle Maps

Proportional Circle Maps represent data by showing them in relation to the size or proportion of circles on a map. The map above illustrates the different populations in state capitals around the U.S. by the size of the circle which is connected to the map key in this case the bigger the circle the larger the population.

Choropleth Maps

Choropleth maps are maps that use colors, shading and the insertion of symbols to represent sets of data like the map above. In the choropleth map above it takes advantage of using different colors and a key to what the different colors mean to show the difference in population densities in countries around the world during the period that this map was created.

Dot Distribution Maps

Dot distribution maps like the one shown above are maps that use dots as a way to represent a population. A population could be anything from people, wildlife or vegetation or anything else that one wants to represent in a map. The one above is representing the Hispanic Population by using red dots and also a scale to let the viewer know what the dots represent on a numerical scale as well.

Propaganda Maps

The maps above is a propaganda map from Nazi Germany during World War II. This was an era in history where I think that propaganda maps were widely used in both Germany and the U.S. as well as other countries I'm sure. Propaganda maps are basically maps that can generalize the entire truth or but more emphasis on particular side of an issue like Nazi Germany has done in the map above.

https://www.msu.edu/~wandless/NaziPropaganda1.html

Hypsometric Maps

Hypsomertric maps are topographic maps that show differing elevations in multiple ways that include shading with colors and the use of contour lines. These are the most common ways to show elevation changes in hypsomertric maps and both these techniques illustrated in the map above.

PLSS Maps

PLSS Maps or Public Land Survey System is maps used to subdivide the United States. This is done by subdividing the land in to rectangular areas as can be seen in the PLSS map above.

Cadastral Maps

Cadastral maps are used for both public and professional references. They are in a basic definition a survey map. They can be used by companies such as real estate and shows how towns or villages could or will be laid out.
http://www.google.com/imgres?q=cadastral+maps&hl=en&gbv=2&biw=1366&bih=532&tbm=isch&tbnid=GM6RsG5B15oxpM:&imgrefurl=http://www.earobinson.com/pages/contextual_history.html&docid=HGUnBVDHOBBStM&imgurl=http://www.earobinson.com/images/SupportImages/Image_20.jpg&w=673&h=548&ei=ZpS-TqemGdOK2QXN4Y2zBQ&zoom=1&iact=hc&vpx=602&vpy=208&dur=3572&hovh=203&hovw=249&tx=170&ty=124&sig=107395654614239701683&page=5&tbnh=143&tbnw=176&start=49&ndsp=12&ved=1t:429,r:8,s:49

Thematic Maps

Thematic maps are maps that show relationships of different categories of for example people. In the map above this thematic map shows the party of control in each governor's office in the contiguous 48 states in the U.S. It does this by using state boundaries lines to distinguish categories as well as using color codes being red for Republican and blue for Democratic. Another distinction of Thematic maps is that they do don't show any physical features of the land they are portraying they are simply used to help viewers distinguish between categories.

Topographic Map

The map above is an example of Topographic map or a contour map which differs from a planimertic map because it projects relief features through the use of contour lines. These lines are illustrated in the map above showing varying elevations. Topographic maps are a good resource for someone who is going to try to travel on foot through an unknown territory because it gives them an idea of what to expect in the upcoming territory that they intend to travel over.

Planimetric Map

This has the correct characteristics to qualify as a planimertric map for multiple reasons. The first being that it shows no relief features. Meaning the map does not contain information about different elevations of the contents contained inside the map. The next reason it qualifies is it maps out many features that are generally found when looking at a planimertic map for example, it shows roads going through the area along with many features located off these roads that can best be described as houses, bus stations and different areas normally found within a city.

Mental Map

I think this is a good representation of a mental map. It shows someone's perception of Africa from prior knowledge. Then it shows the new perception of Africa after learning more about it in a unit study. The first mental map that is drawn here I think is an excellent example of how your perception of a place you have never been to or learned about can be very different from the real thing once you have seen or learned about that place. http://www.google.com/imgres?q=mental+map&hl=en&sa=G&biw=1525&bih=594&gbv=2&tbm=isch&tbnid=SHm49qE5laTFEM:&imgrefurl=http://manciasmaps.blogspot.com/2010/07/mental-map.html&docid=emzHCFka-HAdDM&imgurl=https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi6-Ahssrp3z4DzLvkLpdA9SHyz-5gFPiuAVmdjA4-SuZ_OvKpik6VUTFvoMz7DsiDQJx_c5ntb2QZ6LDjxW90vmJGtgjOtVPOTUFkTbsPkvxm2H8l1dXp8nIHcmAkM6Zf5T0gARN0YCw5P/s1600/Mental.gif&w=540&h=518&ei=z1q5TuawN9L82gWDm73LBw&zoom=1&iact=rc&dur=16&sig=107395654614239701683&page=2&tbnh=118&tbnw=127&start=28&ndsp=26&ved=1t:429,r:24,s:28&tx=66&ty=42
