Cool! New Online Map Draws on Population

Friday, October 2nd, 2009

From the Article:

A new world atlas which concentrates on population rather than land mass has been published.

Researchers from the University of Sheffield created the online atlas of 200 maps that have been redrawn to show, at a glance, which cities are the largest, how all urban areas compare, and whether many or few people live in the countryside.

The images, which were created as part of a Leverhulme Trust project to remap the world and extend the Worldmapper project, have been created using population distribution data so viewers can understand how many people make up each nation.

The new world guides break with the 500-year tradition of conventional cartography which shows compass directions as straight lines.

We added a new series of maps which show grid-based cartograms showing each territory shape according to its population distribution. Those can be found at our new Country Cartograms. The territories can be selected via an interactive map or over a list of the new maps.

Spend some time here, plenty of interesting and potentially useful resources.

From the “About” Worldmapper Page (Worth Reading)

This website contains 696 maps, with associated information and PDF ‘poster’ file. Each map relates to a particular subject. Click on the ‘Thumbnail Index’ which gives thumbnail previews of the maps, ‘Map Categories’ which is classified to see the choice, or a new option ‘A-Z Map Index’, and view a map and associated information. There is also a Site Map and Help page. The country cartograms contain 171 maps showing a population grid for each covered territory/region projected on a cartogram. More information on the country cartograms are explained on this info page.

Google Earth Application Maps Carbon’s Course

Friday, October 2nd, 2009

From the Article:

Google Earth — the digital globe on which computer users can fly around the planet and zoom in on key features — is attracting attention in scientific communities and aiding public communication about carbon dioxide. Recently Google held a contest to present scientific results using KML, a data format used by Google Earth.

“I tried to think of a complex data set that would have public relevance,” said Tyler Erickson, a geospatial researcher at the Michigan Tech Research Institute in Ann Arbor.

The application is designed to educate the public and even scientists about how carbon dioxide emissions can be traced. A network of 1,000-foot towers across the United States is equipped with instruments by NOAA to measure the carbon dioxide content of parcels of air at single locations.

At the bottom of the article (in the related resources section) you’ll find more information including the actual Google KML file and a few videos.

New from Google: “Place Pages”

Thursday, September 24th, 2009

Another day and more new/updated resources from Google. Yesterday, it was a video project with the Wharton School of Business and Sidewiki.

Today, Greg Sterling at Search Engine Land introduces a change to Google Maps named “Place Pages” that replace the “info window” that previously appeared when doing some map searches. Sterling says the changes present the information “much more effectively.”

Sterling writes:

The new “Place Pages” offer a more user friendly presentation of the same information. Also launching today are Place Pages that cover cities, neighborhoods, points of interest and transit stops, in addition to business locations. (The Place Pages are accessible from the “more info” link associated with the listing or result.)

Greg’s post is full of screenshots that illustrate the changes.

The idea behind Place Pages, according to Google is to “give you all the info about a place, in one place.”

Online Digital Maps: Getting Ready for 3-D Street Maps from Tele Atlas

Monday, August 17th, 2009

A very interesting read. The article focuses on a company named Tele Atlas.

From the Article:

Meet the people at Tele Atlas, the company that provides so-called “base maps” to such high-profile clients as Google, MapQuest and RIM, the maker of the BlackBerry. Tele Atlas also provides digital-mapping services for its corporate owner, the portable-navigation company TomTom.

It goes on…

Images collected by the vans’ cameras don’t make it to the public because Tele Atlas doesn’t have an application like Google Street View. But it soon may have something that’s arguably even better.

That brings us to the vans’ side-sweeping lasers. As the vans drive, their lasers constantly scan the road and everything around it, recording information that Tele Atlas calls the “first reflective surface.” This includes the width, height and contours of every building the van passes.

This data, when combined with the images captured by the cameras, will help Tele Atlas create a 3-D world.

Three-dimensional digital maps already are common in Japan and Western Europe. But 3-D maps are still in their primitive stages in the U.S., where their quality depends on the type of device they’re displayed on.

Within 18 months, Tele Atlas hopes to develop a powerful navigation system whose images will look almost identical to the surroundings through which we travel.

U.S. Holocaust Memorial Museum Adds New Data To Google Earth

Thursday, July 30th, 2009

From the Announcement:

The United States Holocaust Memorial Museum announced today the update of its Google Earth initiative, Crisis in Darfur, with U.S. Department of State data that shed new light on the extent of the genocide in Darfur.

The new data show that more than 3300 villages have been damaged or destroyed in the Darfur region of Sudan, primarily between 2003 – 2005. This is more than twice the number that were identified in previous U.S. government assessments, and strengthens the evidence of a vast, targeted campaign of destruction against civilians in the region. The updated data come from recent analysis of high resolution satellite imagery, released by the Humanitarian Information Unit of the U.S. Department of State in July 2009.
[Snip]
For the first time, the data in Google Earth also include hundreds of “before and after” satellite images of villages throughout Darfur.
[Snip]
Crisis in Darfur, a Google Earth layer tracking the path of destruction in Darfur, was launched in April 2007. The following year the Museum launched its second Google Earth initiative, World Is Witness, which brings together testimonies, photographs, videos, and other first-hand data documenting the lives of people affected by contemporary genocide. Both of these layers can be found in Google Earth’s Global Awareness folder under the heading “USHMM,” or at the Museum’s Web site, www.ushmm.org/maps/.

Resource of the Week: Historical Aerials

Monday, June 29th, 2009

Resource of the Week: Historical Aerials
By Shirl Kennedy, Senior Editor

Here’s another time-sink for you. How could you not love this site?

HistoricAerials.com provides free online access to historic and current aerial photography. You can view aerial photography from the 1930s through today. Use our multi-year comparison tools to detect changes in property.

If you just want to look at cool aerial pictures, scroll down to the bottom of the page, to Points of Interest. Click on the Show Categories link. Those who regularly follow us on ResourceShelf know that we kind of got lost looking at aerial pictures of sports stadiums old and new, such as:

(We were, however, less than crazy about the fact that after choosing a category to browse and clicking on an image, we were basically bounced out of that category when the large-size image was displayed, and we had to go back and start all over again.)

Of course you’ll want to click on the Oddities category, although right now, there are only four images available — Michael Jackson’s Neverland Ranch (2005), a blimp and its shadow (1957), Airliner in Flight (2002), and the ever-popular “Boneyard” of mothballed aircraft at Davis-Monthan Air Force Base (2004)

Other imagery categories include: airports, American cities, amusement parks, construction, landmarks, mansions, military, states, Texas, zoos. Some categories have only a few images. Others are stocked with more.

If this was just a collection of static aerial imagery, it wouldn’t be much different from other, similar sites like Bird’s Eye Tourist, for example. But Historical Aerials has a variety of tools that allow you to search for a geographic area, manipulate the images, extract more information from them, and look at images from the same location over a number of different years. A detailed FAQ describes how to do such things as pan, zoom, find latitude/longitude, measure distance, etc. You can choose to overlay roads, counties and cities.

Note from the U.S. map on the home page that historical imagery (back to 1930, in some cases) is available only from certain limited geographic areas — indicated in dark green. “Modern” imagery of the light green areas covers the years 2003-2008. When you initially display an image, labels on the right side indicate which years are available. You can use a slider tool to compare images from two different years.

Note also that the images have the Historical Aerials logo on them. You can purchase logo-free images, which may then be used for publications, etc.

Historical Aerials comes to you from Nationwide Environmental Title Research, LLC (NETR). You may already be familiar with their excellent directory of links to free online public records searches. (They also offer a variety of fee-based public records searches and information.)

Google Maps Let’s You Discover “What’s Here”

Monday, June 22nd, 2009

From a Blog Post:

On Google Maps, we try to label important places directly on the map tiles. But sometimes, it seems more helpful to just click on a point and ask “What’s here?”. Now you can do exactly that with an option we’ve added under the right-click menu. When you click on “What’s here?”, we give you the most relevant result representing that location, whether it’s a specific address, a natural entity, or a place name.

This feature takes into account the zoom level you’re looking at, and gives you the most appropriate geographical entity at that point. For example, if you’re zoomed in closely on Manhattan, you can get the full address of a point by clicking on “What’s here?”. Additionally, by combining this with the “At this address” feature that you may have seen in the left-hand panel, you can also see a list of the businesses located at that place.

Google Updates Satellite Imagery of Tehran

Saturday, June 20th, 2009

Word from Google today alerting us that they have just updated their satellite imagery database with new images of Tehran taken on Thursday, June 18th at approximately 11:15 A.M. local time.

You can get a preview via this blog post or view all of the new images using this KML file with Google Earth. The imagery come via the company’s partnership with GeoEye.

The images…were taken from GeoEye’s IKONOS satellite, which images at roughly 1-meter per pixel. We are continuing to work with GeoEye to see if we can provide a higher resolution update from the GeoEye-1 satellite, which would be at 0.5-meters per pixel, but this is subject to weather constraints

You can also find satellite imagery of Tehran via Yahoo Maps (via i-cubed and GeoEye) and Bing Maps (via DigitalGlobe)

Cool Feature! Landmarks to Be on the Lookout For When Using Bing Maps & Directions

Saturday, June 13th, 2009

Today, we noticed what might be a new feature (at least to us) from Bing Maps. We’ll call it “landmarks to lookout for” while driving. In other words, as you drive the selected route, Bing offers not only offers directions but also selected locations you’ll pass during your drive to help you stay on course. They’ll also tell you if you’ve driven past your destination.

Here are three examples.

1) A drive from Zip Code 10036 (New York City) to Suffern, New York.
Note event #7 on the route. It states that you’ll pass a Pizza Hut in 5.6 miles. Event #12 tells you that if you make it to a specific location, you’ve gone to far.

2) A drive from 60091 (Suburban Chicago) to Downtown Chicago.
Note event #5. It says that an Embassy Suites Hotel is on the corner. And again, the final event tells you if you’ve gone to far.

3) A drive from Orange County, CA to Beverly Hills, CA.
Event #1 says that you’ll pass a Carl’s Jr. restaurant in 1.1 miles. Event #5 notes that a Travelodge Motel is on the right in less than a mile.
