Google Earth A to Z: Street View, Sharing, and Smoots | Google Earth Blog | Digital Cartography | Scoop.it

Google first added Street View imagery to Google Earth in 2008, and gave it a substantial upgrade in 2010 with the release of Google Earth 6. Rather than having a separate layer for Street View, they added a "pegman" icon to the controls on the right side of the screen, very similar to how it works in Google Maps. Here's a quick video on how to use it::.....

Per Square Mile: If the world’s population lived like… | Digital Cartography | Scoop.it
Shortly after I started Per Square Mile, I produced an infographic that showed how big a city would have to be to house the world’s 7 billion people. There was a wrinkle, though—the city’s limits changed drastically depending on which real city it was modeled after. If we all lived like New Yorkers, for example, 7 billion people could fit into Texas. If we lived like Houstonians, though, we’d occupy much of the conterminous United States.

 

Here’s that infographic one more time, in case you haven’t seen it:....

Before and After 1940: Change in Population Density

Before and After 1940: Change in Population Density | Digital Cartography | Scoop.it
This week's visualization from the U.S. Census Bureau looks at county-level changes in population density for the 1930-40 decade, comparing and contrasting it with the 1920s and the 1940s.

 

County-level population change for the 1930s differed from the 1920s or the 1940s, as shown in this set of three maps. In the 1920s, a number of predominantly rural counties in the nation's eastern half saw declines in population and population density, often reflecting outmigration to cities. During the 1930-1940 decade the pattern reversed, with population and population density declines primarily located in the Great Plains. Between 1935 and 1940, 12 percent of the population moved to another county or state. This represented a lull in population movement that changed during and after WWII as geographic mobility increased in the U.S. For instance, between 1940 and 1947, 21.5 percent of civilians moved to different counties or states. In the 1940-1950 period, population density increased for the more urban and populous counties in the Northeast and Midwest, but declines were widespread in predominantly rural counties.

 

SOURCE: Maps are based on decennial census data 1930 to 1950. National migration figures quoted in the text are from the 1940 decennial census and the 1947 Current Population Survey.

 

NOTE: County boundaries are based on 2010 geography, to ensure comparability between decades. For counties in which there have been changes in extent between 1920 and 2010, decennial census data are used as the basis for estimates of historical populations. Data values were rounded to the nearest whole number before classing.

Mapping the Olympic Medals – An Esri Story Map

Loads of companies and online publications are mapping the Olympic metal count, including most of the large online news outlets and now Esri via their popular story map resource (http://mapstories.esri.com). The latest Esri story map is called Mapping the Metals and provides a simple to use map UI (think ArcGIS Online) to share real time (almost) updates of the geographic distribution of the Olympic medals via data derived from heroku.com. Click on a country’s medal count icon and you’ll be taken to that country’s official page on the 2012 Olympics website for more info on the athletes. The story map also provides users with quick sharing to facebook and Twitter although no apprent embed map option is provided – if it is then it’s hidden pretty well! Check out this latest story map at http://storymaps.esri.com/stories/olympicmedals/

Businessman claims city of Chicago stole his maps, threatens to sue

Businessman claims city of Chicago stole his maps, threatens to sue | Digital Cartography | Scoop.it
The last thing you want to do in Chicago is cross City Hall.
But a local mapmaker says he's fed up and preparing to sue Mayor Rahm Emanuel's government after the city allegedly "stole" his maps nearly a decade ago and has refused to pay him royalties.
Christopher Devane, founder of Big Stick/Neighborhood Ties, told FoxNews.com that the city repeatedly has rebuffed his appeals. Though maps might seem a matter of public domain at first blush, Devane claims that the city -- and subsequently other companies -- have gradually plucked away at his work.
"They just refuse to acknowledge the fact that they plagiarized my map," he said.
A cursory glance at the map Devane produced and the map used on the city's Geographic Information Systems website shows striking similarities. Though the color scheme and design is different, each map contains similar neighborhood boundaries and labels.

Google Maps Mania: African Elephant Populations on Google Maps

Google Maps Mania: African Elephant Populations on Google Maps | Digital Cartography | Scoop.it

The Save the Elephants charity has created the Elephants in Peril website with the help of a Google Earth Outreach Development Grant.

 

The website includes two Google Maps to show the location of where elephants are being illegally killed in Africa and the current African elephant population density. The maps were created with the help of Fusion Tables and Google Maps Engine.

 

By creating and maintaining these two maps Elephants in Peril hope to bring together public data sets and to reveal the complete story of elephant populations over time and understand what trends can be seen.

MAPS: People Used To Think California Was An Island

MAPS: People Used To Think California Was An Island | Digital Cartography | Scoop.it
The maps come from a new collection of 800 "California as an island" maps at the Stanford Libraries. They collected by Glen McLaughlin, one of the nation's top map collectors.
"To my knowledge, it is the largest collection featuring California as an island in private hands in the world," said McLaughlin. "The collection was built over a 40-year time period, from 1971 to last year."

 

"California and the Northwest coast of America was one of the unexplored places on Earth, along with Antarctica and Australia," McLaughlin said in a statement from Stanford University.
Here's how it started, from the Stanford release:
The earliest Spanish maps from the 16th century show a continuous coastline, but a Carmelite friar, Antonio de la Ascensíon, accompanied Sebastian Vizcaíno on his West Coast expedition of 1602-03 and apparently drew a map depicting California as an island around 1620.

 

Plunder was commonplace, and Spanish maps were a hot commodity. They were also a state secret. It's generally accepted that the Dutch captured a ship en route, and the charts were waylaid to Amsterdam. What we know for sure is that the maps were widely copied.

 

Perhaps it's just what the Spanish wanted, suggested [says Stanford Library fellow Rebecca] Solnit. "I've been told that Spain knew it wasn't an island, but it was politically expedient for others to think it was. They weren't going to share what they knew with everybody else."

 

Enough was enough in 1747, when King Ferdinand VI of Spain issued a royal decree proclaiming, "California is not an island."
The representation of California as an island was present on a few Asian maps even into the 1860s. Here are several of the maps showing California as an Island that Glen McLaughli picked out as iconic maps from the collection.

Cartograms of State Populations in 1890, 1950, and 2010

Cartograms of State Populations in 1890, 1950, and 2010 | Digital Cartography | Scoop.it

The size and overall distribution of the U.S. population has changed over time, as some states--especially those in the South and West--have grown faster than others. This series of cartograms shows the distribution of the population in 1890, 1950, and 2010. A cartogram is a map that represents the size of geographic units by a statistic such as population count instead of by actual land area. In each cartogram below, one square represents 50,000 people.

 

SOURCE: Census 2010 tables showing historical populations for states based on current boundaries.

 

NOTE: Population counts for 1890 do not include "Indians not taxed." The number of squares per state was calculated by dividing the state population by 50,000 and then rounding to the nearest whole number.

Mapping the future of climate change in Africa

Mapping the future of climate change in Africa | Digital Cartography | Scoop.it

Our planet's changing climate is devastating communities in Africa through droughts, floods and myriad other disasters.


Using detailed regional climate models and geographic information systems, researchers with the Climate Change and African Political Stability (CCAPS) program developed an online mapping tool that analyzes how climate and other forces interact to threaten the security of African communities.


The program was piloted by the Robert S. Strauss Center for International Security and Law at The University of Texas at Austin in 2009 after receiving a $7.6 million five-year grant from the Minerva Initiative with the Department of Defense, according to Francis J. Gavin, professor of international affairs and director of the Strauss Center......

The Explanatory Power of Data Points | eagereyes

The Explanatory Power of Data Points | eagereyes | Digital Cartography | Scoop.it

As newspaper graphics go, scatterplots are a fairly advanced technique. They tend to show a reasonably large amount of data as single points, and they require the reader to have an idea what to look for. Most newspapers never bother using scatterplots for that reason, which is really too bad. With some explanation, a scatterplot can be a very effective means of displaying data, and in particular to allow the user to drill into the data a little bit.

 

In 2010, The New York Times’ Hannah Fairfield and Graham Roberts created a wonderful interactive visualization of the pay gap between men and women (requires Flash). While at first it seems like a straightforward scatterplot, there are some simple yet clever additions that make it much more approachable.
