Black and white aerial photo

www3.shropshire-cc.gov.uk/.../lan/lan_f02.htm

This map is a black and white aerial photo and it is similar to the infrared aerial in some ways, but also has its own unique perspective and differences from other maps and photos. In this map, it is important to see the trend that the black and white photo is able to over more of a finner scale and gradient to the overall larger picture. In this photo, unlike the infrared, there is only a black and white scale so it gives the map and geographical features more texture and pattern and therefore the interpreter of the map is able to see differences in detail of the landscape, which might have been missed if there were simply color differences.

Infrared aerial photo


This is a photo known as an infrared aerial photo that is also considered a very different type of map because it is able to show the land in a way that provides different coloring through the natural changes in the landscape. This map is one taken from the natural preserve on Grover Island and it is really important and useful because they kinds of maps and photos are usually taken from the air, allowing a somewhat larger section to be photographed, in order to have a bigger frame of reference, and to have this large area mapped in less time than it would to walk through and map it by foot. Finally, the colors of infrared aerial photos are able to portray the sharp natural boundaries among the land as well as provide useful geographical features.

Statistical map


The map shown here is an example of a statistical map because it shows the relative rates of success in science of white students across he United States. This is a great example of a statistical mp because there are no absolute values, such as Florida is 100 I.Q. points lower than students in Idaho, it simply states that in reference to Idaho, Florida is lower. This map proves its usefulness in many situations but most importantly when strictly "fact" data is not necessary, but simply relative relationships are most important.

Cartogram


This is a map known as a cartogram because it takes information and displays it on a "normal" map, or one that most people are use to encountering, bu than changes the area so that it is a more visual representation of how certain characteristics affect different areas. In this specific example, a Mercator Projection is taken and then has the statistics of poverty across the world applied to it, and then is "distorted" to show the percentages in area, not simply by shading, coloring, or patterns. I think that most bizarre part of this map is that, living in America, we are use to seeing the US as a huge country, however, in this map the United States is barely even visible. Although this is a reassuring thing, its a little hard to think about when referenced to places like India and China.

Flow map

This map of the Florida Everglades and the flow of water in the past, the natural flow, the present, our man-made flow, and the future, a return to a somewhat natural flow, takes the type of map it is, a flow map, and uses it in its literal terms. The above map tracks the flow of water that is released from the everglades and shows how its man-made changes in the past has severely changed the wildlife and even geography of the land in South Florida. This map is specifically a flow map because it shows how this water flows throughout Florida and, in this case, as in most flow maps, is very important because it is not contained and conformed by boundaries and therefore is able to show the effects of one factor over a much larger scale.

Isoline map


The above map is an example of an isoline map because displays a map of a small portion of Nova Scotia in which the consideration of a new "mega" mall is being built and the costs and benefits are trying to be assessed. This map is important because it shows the trends in increased patronage as one gets closer to the actual mall and by placing lines around similar levels of anticipated shopping, it is much easier to see the biggest area of impact. This map is helpful because if the highest level of patronage had a circle that bulged on one side, then he cartographers could help the builders of the mall to perhaps move the location of the mall more to the center of the actual circle.

Proportional circle map

http://scienceblogs.com/grrlscientist/2007/12/giraffe_species.php

The above map is a very unique type of map because it is a proportional circle map, but it is one that relates to science and genetics. I think this is one of the best maps that I have found because the most important thing that I have learned in this class is that all things can be maps, if they explain or help the unknown become known, something that this map does well. This particular map represents different phenotypes of giraffes and by the size of their circle, their relative abundance in the world, helping to determine their relationship to one another and their ancestral placement.
