"These jarring moments expose how Google Earth works, focusing our attention on the software. They reveal a new model of representation: not through indexical photographs but through automated data collection from a myriad of different sources constantly updated and endlessly combined to create a seamless illusion; Google Earth is a database disguised as a photographic representation. These uncanny images focus our attention on that process itself, and the network of algorithms, computers, storage systems, automated cameras, maps, pilots, engineers, photographers, surveyors and map-makers that generate them.”
"[This map's] an unabashedly generalized interactive population density map inspired/stolen from a map by William Bunge entitled Islands of Mankind that I came across on John Krygier‘s blog. I thought Bunge’s map was a novel way to look at population density, and I’ve tried to stay close to the spirit of the original."
The green dots on this map representing Starbucks locations which are obviously clustered in major metropolitan centers. Cross-referencing this Starbucks address location with population data, Davenport explains his mapping technique: "By counting the number of people who live within a given distance to each Starbucks, we can measure how well centered Frappuccinos are to the US citizenry. In other words: draw a 1-mile circle around every store, then add up the % of the population living within the circles. Repeat for 2, 3, 4....100 miles." The result of this data is a fabulous logrithmic S-curve which explains much about the American population distribution.
This is another old classic image that I might have shared earlier but it merits repeating. As Salvatore Natoli (a leader in geography education) once said, "In our society we unconsciously equate size with importance and even power." This is one reason why many people have underestimated the true size of Africa relative to places that they view as more important or more powerful.
This is a clip from the TV show West Wing (Season 2-Episode 16) where cartography plays a key role in the plot. In this episode the fictitious (but still on Facebook) group named "the Organization of Cartographers for Social Justice" is campaigning to have the President officially endorse the Gall-Peters Projection in schools and denounce the Mercator projection. The argument being that children will grow up thinking some places are not as important because they are minimized by the map projection. While a bit comical, the cartographic debate is quite informative even if it was designed to appear as though the issue was trivial.
Questions to Ponder: Why do map projections matter? Is one global map projection inherently better than the rest?
I found these cartograms from an article in the Telegraph and was immediately impressed. The cartograms originated here and use data from the Global Rural-Urban Mapping Project as to create the int...
This series of cartograms shows some imbalanced populations (such as the pictured Australia) by highlighting countries that have established forward capitals. Question to ponder: Do forward capitals change the demographic regions of a country significantly enough to justify moving the capital?
" A new online tool released by the Department of the Interior this week allows users to select any major stream and trace it up to its sources or down to its watershed. The above map, exported from the tool, highlights all the major tributaries that feed into the Mississippi River, illustrating the river’s huge catchment area of approximately 1.15 million square miles, or 37 percent of the land area of the continental U.S. Use the tool to see where the streams around you are getting their water (and pollution)."
"David Greene talks to writer Jeremy Miller about the American Centroid. That's the place where an imaginary, flat, weightless and rigid map of the U.S. would balance perfectly if all 300 million of us weighed the exact same."
I'm sure most of you have seen the 2008 version of these fantastic maps and cartograms and they've been a go-to reference for me since the last election. The typical red state/blue state map conceals much concerning the spatial voting patterns in the United States and fails to account for the population densities of these distributions. That's what makes this county level voting maps and cartograms so valuable.
Questions to Ponder: What new patterns can you see in the county map that you couldn't see in the state map? What do the cartograms tell you about the United States population?
Not every state is equally impacted by migration, and the demographic profile of migrants is different for every state. This is an online mapping tool to search a large database that can give the user state specific information about the impact of economics and politics based on migration from Latin America and Asia on any given state.

Excellent electoral geography maps from the U.S. presidential election of 2008. What are the major patterns you see? What do these patterns in say about the politics, culture and demographics about these places?
"The WomanStats Project is the most comprehensive compilation of information on the status of women in the world. The Project facilitates understanding the linkage between the situation of women and the security of nation-states. We comb the extant literature and conduct expert interviews to find qualitative and quantitative information on over 310 indicators of women's status in 174 countries. Our Database expands daily, and access to it is free of charge."
With assistance from the Geography Dept. at Brigham Young University, the WomanStats Project provides important data and maps regarding issues of gender, access and equity with a spatial perspective.
More than 10 million Americans moved from one county to another during 2008. The map below visualizes those moves. Click on any county to see comings and goings: black lines indicate net inward movement, red lines net outward movement.
Ever since my first visit to to Disneyland, I was intrigued by the the ride 'It's a Small World After All." As a youngster, it was an opportunity to get in cool boat ride that I always regretted half way into the ride once the song was firmly chiseled into my mind. This blog post explores the curious and fascinating geographical imaginations, the visions of folk cultures and global harmony behind this Disneyland ride. This fabulous map charts that vision.
