A new infographic uses GPS to map out the world's shipping routes over a year's time. A new infographic uses GPS to map out the world's shipping routes over a year's time. Courtesy of German researchers at Carl von Ossietzky Universitat, the map is based on the data for a year's worth of itineraries from actual cargo ships -- 16,693 of them, actually -- gathered from LLoyd’s Register Fairplay and the Automatic Identification System, which tracks vessels partly by using GPS. It's from a paper entitled, "The complex network of global cargo ship movements” (.pdf) by Pablo Kaluza, Andrea Kölzsch, Michael T.

Axis Maps was formed in 2006 by 3 graduate students finishing their advanced degrees in Geography at the University of Wisconsin-Madison. Having originally entered grad school to study traditional print cartography and GIS, we quickly became engaged with the rapidly changing field of interactive mapping. Google Maps had launched the previous spring, while more and more internet users were growing accustomed to having interactive maps as a part of their online lives.
However, we were surprised to see that the cartographic fundamentals and traditions we had been studying were falling by the wayside. Instead, these new maps focused on the technical aspects of delivering geographic content over the web rather than clear communication through cartographic design. We formed Axis Maps to bring Cartography to what was becoming a technical field. Our work has been written about and featured in: The Boston Globe, The Atlantic, Gizmodo, Fast Company, and Directions Magazine. Dafont.com.

Figure 3 An example screen from ColorBrewer.org, an online tool offering color specifications for each color in schemes suited for thematic maps. Color schemes are grouped into sequential, diverging, and qualitative sets. Figure 4 Example diverging schemes.
Diverging data may have an obvious structure, such as positive and negative values diverging from zero (Figure 4Figure 4c). Internet users (per 100 people) | Data | Map. Subtleties of Color: The “Perfect” Palette. About a year ago, we published a blog post framed as a letter to NASA , asking them to stop using rainbow color scales. The post was written out of a general frustration with rainbow color scales, but especially out of seeing field experts and leaders, like NASA, using a perceptually incorrect color scale. We weren’t alone. Robert Simmon from NASA’s Earth Observatory has been crusading for the same changes. He’s made great progress, and as a continuation of that, he’s responding to our “letter” with a brilliant series of blog posts on proper use of colors and color scales.
Despite the near-ubiquity of the rainbow palette—which distorts patterns in the underlying data—the basics of using color to represent numerical data are well-established. This 1823 map by W. By the mid-1960s cartographers had already established guidelines for the appropriate use of color in map-making. Of the three components of color—hue, saturation, and lightness— lightness is the strongest. Color Blindness Article. By Dr Alex Wade, Research Fellow at Stanford University (this article appeared in Planet Medica, April 2000) The next time you go strawberry picking, imagine how much harder it would be if the fruit were the same colour as the leaves. If you are a man, there is a 10% chance that they are! So is this a problem you need to worry about? Roughly 1 in 10 men are fully or partly colour blind.
Colour blindness is not a particularly serious condition. The effects of colour blindness are so mild that many boys only realise that they have it at a relatively late age. It is important to remember that people with colour blindness generally can see most colours; they just have trouble distinguishing between some shades of red and green. Clever ways to compensate for colour blindness If you are colour blind, there are some strategies that can help. On the positive side, there is some evidence that colour-blind people are much better than average at certain jobs. Footnote: What Is Color Blindness? - Eye M.D.-approved information from EyeSmart. In the retina (the light-sensitive tissue lining the back of the eye), there are two types of cells that detect light: rods and cones. Rods detect only light and dark and are very sensitive to low light levels. Cone cells detect color and are concentrated near the center of your vision. There are three types of cones that see color: red, green and blue.
The brain uses input from these three color cone cells to determine our color perception. Color blindness can occur when one or more of the color cone cells are absent, nonfunctioning, or detect a different color than normal. Severe color blindness occurs when all three cone cells are absent, and mild color blindness occurs when all three cone cells are present, but one cone cell functions abnormally to detect a different color than normal.
There are different degrees of color blindness. Color blindness is usually something that you have from birth but it can be acquired later in life. Next Page: Color Blindness Symptoms.

It wasn't until 1854 that Cholera struck England once again, that Snow was able to legitimate his argument that Cholera was spread through contaminated food or water. Snow, in investigating the epidemic, began plotting the location of deaths related to Cholera (see illustration).
At the time, London was supplied its water by two water companies. One of these companies pulled its water out of the Thames River upstream of the main city while the second pulled its water from the river downstream from the city. A higher concentration of Cholera was found in the region of town supplied by the water company that drew its water form the downstream location. Water from this source could have been contaminated by the city's sewage. After the panic-stricken officials followed Snow's advice to remove the handle of the Broad Street Pump that supplied the water to this neighborhood, the epidemic was contained.

An Open Geospatial Textbook David DiBiase with contributions by James L. Sloan II, Ryan Baxter, Wesley Stroh, Beth Fletcher King, and many students The Pennsylvania State University The purpose of this text is to promote understanding of the Geographic Information Science and Technology enterprise (GIS&T, also known as "geospatial"). Since I began writing in 1997, it has been a vehicle for me to understand the field better and to help my students do the same. Originally, my students were undergraduates enrolled in the Penn State course GEOG 121 (now 160): Mapping Our Changing World.
Later, I developed an online text for students in our Postbaccalaureate Certificate Program in GIS and Master of GIS (MGIS) degree program (link is external), both offered to adult professionals across the country and around the world through the University's "World Campus. " GIS&T is the intersection of professions, institutions, and technologies that produce geographic data and render information from it. Geospatial Education Portfolio.
