"Google is using a new technology to automatically generate 3D buildings from 45-degree angle aerial photography made by overlapping passes of aircraft. The aerial photos are combined to create 3D models."
Some of the nuts and bolts behind Google Earth might be difficult to replicate in the computer lab, but it is critical to conceptually understand how geospatial data is used today. This series of images shows how important remote sensing is for our modern digital mapping platforms.

"Historian Susan Schulten writes in her book Mapping the Nation: History and Cartography in Nineteenth-Century America that during the 1850s many abolitionists used maps to show slavery's historical development and to illustrate political divisions within the South. (You can see many of those maps on the book’s companion website.) Schulten writes that President Lincoln referred to this particular map often, using it to understand how the progress of emancipation might affect Union troops on the ground. The map (hi-res) even appears in the familiar Francis Bicknell Carpenter portrait First Reading of the Emancipation Proclamation of President Lincoln, visible leaning against a wall in the lower right-hand corner of the room."

I chose this scoop because it relates to slavery, and slavery has something to do with economics. It also has to do with social. This map was used by Lincoln to see the reach of slavery. TOPIC: social
Great historical map of the population density of enslaved people during the 1850s. I would like to see this map with a side by side of the poulation density of modern day african americans. I think they would be very similar due to many people not wanting to leave their culture and tradtion behind. Another little thing i found interesting on this map is where the slaves were the most populated such as along the mississippi and coastal carolinas. This is from the farms having to use massive amounts of water to run and whats better than being right on the water.
"Drawing on data from the 2010 U.S. Census, the map shows one dot per person, color-coded by race. That's 308,745,538 dots in all."
This is an incredibly gorgeous interactive map of population density in the United States. It is very reminiscent of this North American Map with two major differences. On the down side, Mexican and Canadian data are not displayed but on the bright side, the added color component is used to show ethnic categories as defined by the 2010 U.S. census. Please explore this map at a variety of scales and in distinct locales.
Questions to Ponder: Is this a map of ethnic diversity patterns or is it a map of racial segregation? How come? Is there additional information that you would need to decide? This review of the map on Wired and Atlantic Cities described this map as a map depicting segregation: why would they say that?

I recently got my hands on a fabulous atlas entitled Mapping Mormonism which shows the historical geographies of this particular Christian denomination (see a review here). I'll briefly share just this one cartogram above that is from the atlas; it displays territory not by the size of the landmass but by the LDS population living within the given territory. While we would expect to see Utah to be very large on this cartogram, are there other pockets of large LDS populations that are surprising to you? What explains the small spatial distribution patterns of limited diffusion that you see? The LDS church is well-known for its missionary program and proselytizing efforts—does that play a role in this map?
On a related side note I found a curious political/religious map of the United States (a map that is partially explained by understanding some of the patterns on the map above). The most typical religious maps show where particular religions are pre-dominant. This map shows territories marked not by the faith of the residents but by the religion of the local congressmen. This make me wonder: Is this map religious or political? Is there valuable information to glean from this maps or is it simply a fun curiosity? How does the religious geography of the United States impact political geography (or vice versa)?

The Pentagon has upset patriots by labeling the body of water between Korea and Japan in an exhibition depicting various battles fought during the 1950-53 Korean War as "Sea of Japan" rather than "East Sea."
Earlier this week I posted on whether a group of islands off the coast of Argentina should be called the Falkland Islands or Las Malvinas. There is some geopolitical significance to which name you ascribe to particular places. Does it matter if I call the sea to the east of the Korean Peninsula the "East Sea" and if someone else refers to this same body of water west of Japan the "Sea of Japan?" For many years the Sea of Japan has been the defacto name internationally and South Korean officials have lobbied (quite successfully) to bolster the legitimacy of the name within the media, publishers and cartographers and other governments. Last summer, a worker in the South Korean government's Ministry of Foreign Affairs requested that I share some resources that state South Korea's position(see also this 10 minute video), showing their commitment to this rebranding effort. Also see this GeoCurrents article on the subject in 2012, after South Korea's failed attempt to get international recognition.
Questions to Ponder: What other places have multiple names? What are the political overtones to the name distinctions? What are other tricky places on the map where distinct groups would label/draw things differently? Is the map an 'unbiased' source of information?

I agree with Peter Kim and others that are fighting to have the name changed to the East Sea. The term "Sea of Japan" was used in colonial times of South Korea. Now that those times are long gone, it I can understand why South Korea would want to get rid of anything related to that time period. This actually reminds of something that I'm going over in my colonial history class; the Pueblo Revolt (1680). During this time Indians revolted against the Spanish colonizers oppressing them and taking away their traditions, forcibly converting them to Christianity. During their revolt the Indians destroyed many of the Spanish institutions, especially those related to religion. They destroyed churches and even defaced the statues of the saints, and returned to their traditional practices.
This article also reminded of Sri Lanka changing the its colonial name on Government institutions from Ceylon to Sri Lanka. This happened not to long ago. The Island's colonial name (Ceylon) was dropped when they became their own country in 1972. However, the name Ceylon remained on many of the Government institutions (e.g. Bank of Ceylon or Ceylon Fisheries Corporation). However, in 2010 the name was dropped for good.
The Esri Thematic Atlas is a configurable web application that uses a collection of intelligent web maps with text, graphics, and images to talk about our world.
ESRI is moving towards creating a dynamic, authorative, living digital atlas and empowering users to create their own. See this great political map of 2008 U.S. presidential election that is a part of the altas; it goes far beyond simple blue and red states. StoryMaps are also democratizing the mapping process.

First unit is based on maps and atlases. Want to build a range of resources.
The Atlas of True Names reveals the etymological roots, or original meanings, of the familiar terms on today's maps of the World, Europe, the British Isles and the United States. For instance, where you would normally expect to see the Sahara indicated, the Atlas gives you "The Tawny One", derived from Arab. es-sahra “the fawn coloured, desert”.
This is a fun set of maps that forces us to reexamine the historical linguistic roots of place names. Many toponyms have a complicated histories so the actual root of the name is not always a single straightforward translation as shown in these maps. As you explore these maps, most readers will find something the they would dispute, correct, or want to see contextualized more but all in all, it is a fun set of maps.

Great to see what the original names where! Especially for those that are similar to its current name and those that are completely irrelevant!

Welcome, Metafilter visitors! How can you map a sphere unto the plane? well you can't if you want to keep size, shape and proportions. Here are the alternatives... Learn more about the different projections.
We are accustomed to spatial distortion in maps; when we see that same distortion on a picture, it gives us an alternative perspective on the level of spatial distortion that we see on maps. The Azimuthal projections (circular) are my favorite for this photographic project.

This is a rich and fascinating angle on history enhanced by a bounty of beautiful reproductions. Rare is a book this aesthetically pleasing and intellectually original.
"Maps are not merely distilled representations of geographic realities. Over time, they come to represent an organic bundling of history: reconstructed, imagined, and manipulated. Historically, they have been the tools with which expanding empires have legitimized their conquests, imposed identities, and created administrative order, and with which victims have constructed alternative narratives and salvaged their own national memories. Never was this truer than in the period in the eighteenth and nineteenth centuries when a burgeoning Romanov empire joined Austria and Prussia in wiping Poland-Lithuania from the map and absorbing it into their swelling realms. Seegel intricately analyzes the cartography of imperial Russia and Poland-Lithuania as the science evolved and historical demands were placed on it. This is a rich and fascinating angle on history enhanced by a bounty of beautiful reproductions. Rare is a book this aesthetically pleasing and intellectually original. Seegel should be congratulated for creating it, and the University of Chicago Press, for producing it." You may also see this title on Amazon.

On three different occasions, the candidate with the most votes didn't become President of the United States. We call this "The Electoral College Problem." Here a solution. Simple. Mathematical. Rational.
As a disclaimer, I'm not endorsing the removal of all current state borders, but I think that this is a great thought exercise that involves some serious spatial thinking and geography knowledge to create this map (or even to critique and discuss it). This map represents an attempt to restructure the states so that each state would have equal value in the electoral college with roughly equal populations (county borders remained firm). What about the physical and human geography would make some of these "states" better (or worse) than the current configuration of the 50 states? How would this 'redistricting' impact your local region?

"As a kid, I grew up watching the Rocky movies, shadow boxing with my brothers and doing push-ups during the workout montages. One on my favorite scenes was in Rocky II when Rocky runs through the whole city of Philadelphia, thronged by adoring fans as he runs to the top of the stairs to the Philadelphia Museum of Art (and yes, of course I re-enacted that scene when I was there)."
I was thrilled to read an article in the Philly Post by Dan McQuade entitled “How Far did Rocky Go is His Training run in Rocky II?“ This article identifies the locations in movie that were used to capture such a strong sense of place; earlier versions of this article did not have a map, and I wanted to see the images and a map together. That was enough reason to make both an online map on arcgis.com and an interactive web mapping application with an ESRI storymap template.

My family and I have watched the Rocky series a handful of times, and a month or two ago, my grandmother called our house all frantically to let us know that "Rocky" was on TV, in case we wanted to watch it. I used to be big into going for long walks across a few towns every night, and this article reminded me of some of the walks that I had been on, and have actually mapped out. The expression "walking around in circles" does not fully apply to many places, because they have semi-straight roads and often have 90 degree intersections with other roads, which would make it walking in rectangular patterns. I have walked well over 20 miles in a single night, and found myself exploring side roads and looking them up later on an online map of the area. In this article, Rocky runs in a "circular" pattern, but from his house to the final steps that he runs up at a museum, rather than returning to his house. In this map with the article, Rocky is shown as covering a large area on his run, without overlapping the same areas all that often. "Rocky" is a series about achieving dreams and defying odds- actions that are different with different characters and different outcomes in every movie. It makes sense that Rocky covers a little bit of the same ground twice, metaphorically in the movies, and literally on the map, but also that he achieves his destination after going the long and difficult distance rather than a bee-line to the destination, that would defeat the depth of the story. Rocky's run is symbolic as a journey mentally, physically, and spiritually, and is enforced by the route that he was found to have run, as analyzed by this article and its links. While I found myself walking 15 miles to a place, and back in the same night, I was merely part of a cycle. Rocky is a hero because he went the distance.
I too loved this movie growing up. Everytime Rocky was brought up you always remebered the part when Rocky ran up the stairs to the statue after his long training run. Just from his run you see the type of community they lived in. His town was very rundown, but you still got a sense of community by the way people yelled and cheered for Rocky as he ran by. They may not have had much as a community, but they supported each other and took pride in their city. You were able to get all of this just from the different landmarks you saw Rocky pass by on his run. You may not think about it at the time, but the location and scenary really paints a picture of the type of lifestlye and culture Rocky grew up in, and what makes him the man that he is. That is all just from simply paying attention to the landmarks that he runs by. Location really effects a person and you can see that in this movie. Rocky was a fighter who never gave up. His community was the same way. And looking at the map I don't think I was would ever want to run that far. It appeared a lot shorter in the movie than it actually is!
" The Smithsonian Magazine recently dipped into David Rumsey's collection of over 150,000 maps to find some of the best representations of American cities over the past couple hundred years.

"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.”
The quote above from Clement Valla shows some of the problems with trusting too completely in a form of technology if you are not sure how it works or what its limitations are. What does he mean when he says "Google Earth is a database disguised as a photographic representation?" What does this have to do with the term metadata?

This post represents a "sub-issue" which underlies many of today's decisions: How much "information" is really a composite of items that may or may not be related? And how many of our decisions are based on those constructs? As a result, are we liviing in a "house of cards", a fantasy world that is sure to collapse around us one day? It's a scary thought.
I understand that this article mostly depicts the inherent limitations with our current technology within GIS systems but I mostly just found these images to be eerily and awkwardly beautiful. Art made accidentely. Thank-you flawed technology.
Today we take it for granted that through GPS technology we can instantaneously determine our latitude and longitude. This video documents how for centuries it was fairly easy to determine latitude at sea by measuring the height of the sun in the sky, but longitude (determined by the difference in time between local noon and the noon of a fixed point) could only be estimated. The British Empire saw solving the "longitude problem" as the key to solidifying their economic dominance at sea and they established the Board of Longitude in this 18th century "race to the moon." Today the University of Cambridge has digitized the Board of Longitude's archives with a series of five shorter video clips.

Though he never actually crossed it, the Greek mathematician Pythagoras is sometimes credited with having first conceived of the Equator, calculating its location on the Earth’s sphere more than four centuries before the birth of Christ.
This is an interesting article on some Earth-Sun relationships that challenges the dominant north-centered normative view of how to think about our planet. My favorite tidbit of information: "The velocity of the Earth’s rotation varies depending on where you stand: 1,000 mph at the Equator versus almost zero at the poles. That means that the fastest sunrises and sunsets on the planet occur on the Equator, and centrifugal and inertial forces are also much greater there. "
This is a very thought provoking article. I like seeing the established conventions challanged. I also like the conversations around the sense of superiority possed by the Northern Hemisphere. Enjoy!
Definitly changed my way of thinking. also this brings up the many flaws with pre geospatial desinged maps. cartographers could push their own agenda to make their country or area look more promient than it actually is. also another prime example of something that has been taken as fact for many years (nobody questions a world map) and turns out to have some flaws

This fabulous collection of African maps from 1535-1897 represents an historical geographic vision of both Africa and colonial visions of an imagined Africa. I chose this particular map to display because it beautifully highlights the Mountains of Kong. For generations, European cartographers erroneously believed that this long mountain range extended north of the West African coast and across the continent. Currently this map collection is at Plymouth State, NH, but much of it is archive online here.

It is always informative to look at old maps. They show how the cartographers saw the world and how the passage of the map makers revealed the passage of settlements in this case of colonel Europeans.
This collection of maps are interesting as they show how mysterious the African continent was to Europeans. With deep expeditions into the continent expensive, difficult, and dangerous, central Africa remained very much a mystery into the 20th century. The Mountains of the Moon and the Mountains of Kong, the supposed sources of the Niger and Nile river, were completely fabricated guesswork which remained on maps until the 20th century. For central Africa, rather than make guesses as to the terrain, cartographers frequently left the area blank or with scant details.

When I was a graduate student at Penn State, I was introduced to some great people and programs and I'm glad to see that the institution has continued to excel and be a leader. You have probably heard of MOOCs (Massive Open Online Course) and been interested in seeing how this might change higher education in the future. This MOOC is a free 5-week course designed to be an introduction to mapping, GIS and geospatial technologies so you don't need to be a specialists with a mapping background: it's for beginners. I know that many geography teachers tell their students about GIS, but are afraid to teach with GIS because they are worried that it will be too hard. This is an easy on-ramp to 21st century geospatial tools and any geography teacher hoping to modernize their skillset would do well to take this summer course fromthe Program of Online Geospatial Education at Penn State, taught by Dr. Anthony Robinson.
