Unclassified choropleth maps use the technique of assigning color shadings in proportion to the data values. Many cartographers dislike these types of maps because they are unable to classify the information and they feel as if they're losing the ability to communicate the message to the viewer. This map shows the number of internet users in the eastern hemisphere. The colors are assigned to dictate number.

Infrared Aerial Photo



http://images.google.com/imgres?imgurl=http://www.nature.com/nbt/journal/v23/n2/images/nbt0205-165-I1.jpg&imgrefurl=http://www.nature.com/nbt/journal/v23/n2/full/nbt0205-165.html&usg=__lCQafxggNiSeC2JM6N16gvmQRxU=&h=311&w=440&sz=58&hl=en&start=9&um=1&itbs=1&tbnid=ocvPpGgNiiuNSM:&tbnh=90&tbnw=127&prev=/images%3Fq%3Dinfrared%2Baerial%2Bphoto%2Bof%2Bnature%26um%3D1%26hl%3Den%26rls%3Dcom.microsoft:*%26tbs%3Disch:1

Infrared aerial photography is able to show wavelengths that fall outside the range of human vision. IR film is commonly used to produce color-infrared photos since we can't see the wavelengths recorded on infrared film. Furthermore, this infrared aerial photo illustrates a picture of a forest taken from above. The red color in the picture represents the shapes and forms of the trees that we wouldn't normally be able to see.

Black and White Aerial Photo

Aerial photos are another type of remote sensing. Aerial photography is a type of photography in which you take pictures of the ground from an elevated position. Black and white emulsion is sensitive to approximately the same wavelengths as the human eye and therefore, false color isn't necessary since we can already see the wavelengths recorded. This black and aerial photo illustrates Cassat Ave in Jacksonville, Florida (my hometown) which is a suburb, as you can see the houses, trees, roads, and neighborhoods from above.

Lidar Remote Sensing

Lidar remote sensing uses a laser (light amplification by stimulated emission of radiation) instead of radio or microwave radiation. A lidar sensor is associated with the highest features in the landscape. In this specific map's case, the highest feature is the tops of buildings. Lidar is used used to generate elevation maps and identify other landscape characteristics.

PLSS Map

A PLSS map, which stands for Public Land Survey System, is a type of map that facilitates ownership. It is a way to subdivide and describe land in the United States systematically and fairly. The original PLSS surveys were often marked by wooden stakes or posts, marked trees, pits, or piles of rock, or other less-permanent markers, and therefore were not systematic. A PLSS map begins at an initial point and the north-south line that passes through it is called the prime meridian and the east-west line that passes through it is called the base line.

Choropleth Map




http://images.google.com/imgres?imgurl=http://www.bsu.edu/ibb/US/Map/Rug/gmap2.gif&imgrefurl=http://www.bsu.edu/ibb/US/Map/Rug/index.htm&usg=__sCQzuiY3FIB7-LTwR-r3gE1nQ94=&h=400&w=400&sz=6&hl=en&start=1&um=1&itbs=1&tbnid=j4wYeNWPMPNziM:&tbnh=124&tbnw=124&prev=/images%3Fq%3Dchoropleth%2Bmap%2Bstate%2Bunemployment%2Brates%26um%3D1%26hl%3Den%26rls%3Dcom.microsoft:*%26tbs%3Disch:1

Choropleth maps display areal data. A common way to areally average choropleth map data is to either use percentages, which is shown in this map, or denisty (persons per square mile). As shown in this choropleth map, the yellow states' unemployment rate is less than 7.4%, the green states' rate is 7.4%-9.0%, the blue states' rate is 9.0%-10.9%, and the red states' rate is over 10.9%.

A histogram is a graphical display of frequencies, shown as bars, that shows what proportion falls into each category. It is different from a bar graph because the bars are not separated from one another. In this histogram students' test scores are displayed. The height of the bars display how many students fit into each category. As shown, 4 students made a test score of 50-59, 6 made a score of 60-69,10 made a score of 70-79, 8 made a score of 80-89, and 2 made a score of 90-99.

A box plot is a convenient way of graphically depicting groups of numerical data through their five number summaries. This box plot depicts the annual snow depth a Mathsville Ski Resort. The five number summary consists of the minimum value, so in this case it would be 25, the lower quartile (55), the median (78), the higher quartile (101), and the maximum value (130). Therefore, the median snow depth would be around 78.

A correlation matrix is a matrix displaying the relationship between a pair of data sets and serves as a general term to describe the fact that two (or more) variables are related. This correlation matrix displays the data that correlates the bahavior between protein and phage T7. The highest correlation is represented by the color red and the lowest correlation is represented by blue. According to the matrix, there is a correlation between the two, which is shown by the straight line of red blocks.

This is a mental map that a child created to describe their neighborhood. As you can see, the map is not drawn to scale and there definitely was not a certain projection used to display an accurate map of the shape, area, or distance of his or her neighborhood. There is obvious distortion in the size of the houses and buildings, and distance between each of them however; it is the child's personal perception of his or her neighborhood of Coal City, Illinois in the 1940s.

Stem and leaf plots convey the frequency of students' weights in a class according to kilograms. The numbers to the left (the "stems") represent the ten's place and the numbers to the right (the "leaves") represent the one's place. The map displays that 15 kilograms is the most frequent weight in this given class and the majority of the students' weight is under 20 kilograms.
