Google Maps Creates a Completely New Town in the UK

Wednesday, November 4th, 2009

From a Post by Matt McGee:

Google and its UK map provider, Tele Atlas, are cleaning the egg off their faces this week over the appearance of a town called Argleton in Google Maps.
…and there’s even an Argleton place page with photos and more.

Matt also points out that there is Google page with pictures of homes, ads, and links to popular places. He adds that although the British press reported the story over the weekend, the “mystery” has been going on for over a year.

As of 3am on Wednesday, November 4, 2009, you can still find Argleton in Google Maps.

Note from Gary:

Matt’s post also mentions that some have wondered if a town in Maryland named Middle Earth might also be an error, He gives me a shout out (Thanks Matt!) for determining that Middle Earth, MD does exist. My guess is that it’s a section of California, MD. What source(s) did I use to determine it was legit? After not finding Middle Earth, MD in the Getty Thesaurus of Geographic Names I checked another database, the Geographic Names Information Database (GNIS) via the USGS. Run a quick search and you’ll see that Middle Earth, MD is a populated place in St, Mary’s County, MD. It was added to the GNIS is May, 1996. Once again it illustrates that it’s always a good idea (when possible) to check more than one source.

New/Updated Imagery Added to Bing Maps Database

Tuesday, November 3rd, 2009

We’re big fans of Bing Maps around these parts (the “Bird’s Eye view always amazes us) and today Bing Maps evangelist, Chris Pendleton, announced that they’ve just added 9,460 square kilometers of imagery as part of their monthly release

Pendleton writes:

This month’s release showcases high precision imagery for the USA, Canada and the United Kingdom. The biggest drop by far was Greater Vancouver Metro.

Cool! New imagery just a few months before the Winter Olympics.

You can take a virtual tour of some of the new content using the Bing Maps World Tour app.

Note: Although the blog posts says it’s the October, 2009 update, the World Tour app reports it’s the November, 2009 update. We will try to get an answer.

Happy Touring!

More Digitization Underway: This Time Footnote.com is Digitizing the U.S. Census from 1790-1930

Tuesday, November 3rd, 2009

Footnote.com is once again partnering the National Records and Administration Agency (NARA) to digitize massive amounts of content and then make that material available, often for a fee, available online. Footnote is becoming–and for some has already become–and important resource for historians, genealogists, students, and others.

This time around, Footnote.com, is digitizing all publicly available Census materials from 1790-1930. These dates represent the period when all materials (including names) from a given census have been made publicly available. Through its partnership with NARA, Footnote.com will add more than 9.5 million pages of content when the census database project is complete. We’ve learned that Footnote.com is digitizing all of this material on their own.

From a Footnote.com Blog Post:

With over 60 million historical records already online, Footnote.com will use the U.S. Census records to tie content together, creating a pathway to discover additional records that previously have been difficult to find.

The Interactive Census Project Home Page offers much more detail and examples. You can also create email alerts when new states are added to the census database. On the lower-left side of the page you can track the progress of each census has been digitized. As you’ll see, the 1860 census is complete and the 1930 census is just about done.

Searching is free, Footnote provides numerous options to refine your search (here’s an example). Accessing the complete record is fee-based either subscribing to the database for a annually or monthly. You can also by individual documents for $2.95. Btw, Footnote.com also sells institutional access to libraries through EBSCO.

Footnote looks at the census project as a “highway” to assist the researcher in finding more information in other databases.

If you’ve been reading ResourceShelf for a while you’ve seen an increasing number of mention their services. Here’s a list of a few of them,

+ In August of 2009. we posted on the release of a joint project with the National Archives (NARA) to digitize holocaust material.

+ In December of 2008, in a partnership with NARA, Footnote released the largest interactive World War II collection online.

+ In March, 2008 we posted about Footnote.com offering an interactive version of the Vietnam Wall.

Our first post about Footnote dates back to January, 2007.

If you run this search using the ResourceShelf database, you’ll be able to see and read all of our Footnote.com posts.

But wait, there’s more. A quick review of the Footnote “press room” offers up even more projects. You can learn about them here.

The Complete Archive of National Geographic Magazine on Six DVD’s

Sunday, November 1st, 2009

Every now and then a fee-based product comes around that we believe deserves your attention. The following is one of them.

Chris Pendleton on the Bing Blog reminds us that a major digitization project, every issue ever published of National Geographic from 1887-2008, is now available (it was officially released yesterday according to this media announcement) on 6 DVD’s or an external hard drive. That’s right, all of the writing, the legendary imagery, the supplement , even the advertisements are included. For many topics, Nat Geo magazine is a resource that documents people, places, and events, on a global scale. In other words, for all of the reasons just mentioned and many others, makes the magazine an important part of the historical record.

By the way, the reason it was mentioned on the Bing Blog is because Bing is providing some the technology that powers the digitized version this recently released collection.

From the Blog Post

Nat Geo uses Bing Maps in their Geobrowse functionality which allows you to browse a map anywhere in the world to find locations where relevant articles are referenced using geographic metadata.

Yes, we still love paper and those massive collections of past issues of the print version of National Geographic Magazine many people own (where are yours)? They’re also important.

That said, we also hear and read that for today’s student, it’s all about digital access. Yes, of course, that’s rather sad. However, a digitized archive of this size and scope can truly demonstrate the power of digital info technology for people of all ages and turn 120 years of content into important research and learning resources.

Another digitized archive of the magazine was released seven years abut this 120 year collection is the most complete version ever published with more content, more search options, saving/sharing tools, interactive maps, and more. One thing we noticed right of the bat is the that the new version is available for both PC and Mac. The “112 year version” was PC only.

Here are a few fast facts about the new collection. They were gleaned from Nat Geo site (including the video overview) and news release.

+ All Issues from October, 1888-December, 2008 are included

+ Six DVD’s include more than 200,000 pages; 300 wall map supplements, more than 8,400 articles; more than 250,000 photographs

+ All images scanned in high-resolution

+ Flip one page at a time, zoom, print

+ Geobrowse

A new Geobrowse function powered by Bing Maps that allows users with Internet access to search nearly 5,000 locations on a globe that are featured in the magazine’s archive of articles and maps.

+ Search by keyword, date, contributor, and topic; refine by date or content type

+ Browse by month or year

+ Create personalized reading lists; share these lists with other users in the Nat Geo community

+ Pre-loaded “favorite article lists” compiled by experts

National Geographic is selling the DVD’s for $69.95/US and the hard drive version for $199.95/US.

The lowest price we found as of Sunday November 1st was $42.78 from an Amazon.com Merchant. The DVD’s directly from Amazon.com are $44.99/US.

We’ve ordered a copy of the DVD’s and after spending some time with them we will report back.

Digital Globe Annonces Deal with Microsoft to Provide High-Resolution Aerial Imagery to Bing Maps

Sunday, November 1st, 2009

From the Announcement:

DigitalGlobe, [has] announced it has signed an agreement with Microsoft Corp. to launch the Clear30 program, an initiative to distribute high-resolution, 30-cm aerial imagery of contiguous landscapes, initially in the U.S. and Western Europe. These orthophoto mosaics will be available through Bing Maps and through DigitalGlobe channels. The Clear30 imagery will be exclusive to Bing and DigitalGlobe.

[Snip]

The Clear30 initiative is a new agreement that expands the current relationship between Microsoft and DigitalGlobe and reflects a commitment to increase accessibility and use of high-resolution digital imagery. To collect the first ever multicontinental aerial imagery from 30 cm, the companies will use the UltraCamG, a large format digital aerial camera manufactured by Vexcel Imaging GmbH,, a wholly owned subsidiary of Microsoft.

[Snip]

“We’re excited about the launch of the Clear30 program and our continued relationship with DigitalGlobe,” said Steve Stanzel, general manager of Bing Maps at Microsoft Corp. “By providing DigitalGlobe exclusive access to our advanced UltraCamG imagery, we can provide our mutual customers easy access and integration of high-resolution digital aerial orthophotos for vast landscapes around the world.”

Digital Globe provides imagery to many organizations and is also used at Google. Note the Digital Eye copyright at the bottom of this image.

Google Releasing Free and Robust Mobile Navigation Tool

Wednesday, October 28th, 2009

Lately, it seems like each day brings another new product announcement from Mountain View. Today, is no different.

Google is getting into the mobile navigation/turn-by-turn directions business and making the product available for free.

On launch day (November 6th), users will be able to access the service from only one phone, a new phone, the “DROID” from Motorola, and from one carrier, Verizon.

Obviously, more Android-based phones running Android 2.0 from Verizon as well as other carriers will soon begin to hit the streets along with users who can* upgrade their current Android phone.

* “Google is not sure whether Google Maps Navigation will work on older Android phones that will get upgraded to Android 2.0. That depends on the carrier and phone maker, [vice president of engineering at Google for mobile and developers. Vic] Gundotra said.” (CNET)
Greg Sterling from SEL guesses most pre 2.0 phones will be upgradable.

Google is also interested in the iPhone as well as other smartphone platforms but made no commitment as to when the navigation program might be available.

Using the official blog announcement as well as articles from Greg Sterling at Search Engine Land (SEL) and Tom Krazit at CNET, let’s compile some fast facts about the product and its many features:

+ Google Maps for Mobile Has Been Very Successful
Over 50 million global users (SEL).

+ Most Requested Feature Was Was Turn-by-Turn Navigation (SEL)

+ Products Official Name is Google Maps Navigation (Beta)

+ Seven Key Features
1) Automatically updates with new and updated maps. Google now provides their own data for maps in the US.

2) Search by entering text, even just a small amount, and then focus your results.

3) Search by voice (e.g. drive to San Francisco International Airport).

4) Current traffic conditions.

5) Search along a route (e.g. on your current route find the nearest drug store). You can also search by business name.

6) Satellite View provides a 3-D view of the route.

7) Street View. See what the street looks like (landmarks, etc.) before you get there.

This page provides a video overview of Google Maps Navigation as well as separate videos demonstrating each feature.

Refining the Look of Google Maps

Saturday, October 24th, 2009

From a Blog Post:

Today’s changes are intended to keep the same information-rich map while making it easier to pick out the information that is most useful. The changes affect both the ‘Map’ and ‘Hybrid’ styles, and include numerous refinements to color, density, typography, and road styling worldwide. For example, in map view, local and arterial roads have been narrowed at medium zooms to improve legibility, and the overall colours have been optimized to be easier on the eye and conflict less with other things (such as traffic, transit lines and search results) that we overlay onto the map. Hybrid roads have gained a crisp outline to make them easier to follow, and the overall look is now closer to an augmented satellite view instead of a simple overlay.

In some areas the changes are obvious, while in others they are quite subtle. But overall we hope you’ll agree they’re a nice improvement.

The blog post continues with examples of some of the changes.

Online Satellite Imagery: An Interview with Dr. Walter Scott from DigitalGlobe

Sunday, October 18th, 2009

One of the big players in commercial (as opposed to government) satellite imagery is DigitalGlobe of Longmont, CO. They provide images to Google, Bing, and many other companies. They also provide images to the government and military.

In an extremely interesting 7.5 minute (we wish it was longer) audio interview, Joshua-Michéle Ross from O’Reilly Radar talks with Dr. Walter Scott, Executive Vice President and Chief Technical Officer of DigitalGlobe.

Some of the topics discussed include:

+ Uncommon uses of DigitalGlobe satellite imagery
+ Competitive advantages in the satellite imagery business
+ Tools to get imagery in the hands of users
+ Augmented reality

Better Directions: Bringing Maps and Video Together

Friday, October 16th, 2009

From the Article:

A novel navigation system under development at Microsoft aims to tweak users’ visual memory with carefully chosen video clips of a route. Developed with researchers from the University of Konstanz in Germany, the software creates video using 360-degree panoramic images of the street that are strung together. Such images have already been gathered by several different mapping companies for many roads around the world. The navigation system, called Videomap, adjusts the speed of the video and the picture to highlight key areas along the route.

[Snip]

Videomap still provides written directions and a map with a highlighted route. But unlike existing software, such as Google Maps or MapQuest, the system also allows users to watch a video of their drive.

[Snip]

When given Videomap directions, drivers made the correct turn 80 percent of the time. With a map and text directions, the drivers made the correct turn only 60 percent of the time.

[Snip]

Arzu Coltekin, a senior researcher at the University of Zurich who works in the Geographic Information Visualization and Analysis Division, finds the work interesting. Some might say that a system such as Videomap isn’t necessary because of the proliferation of GPS receivers in cars, but Coltekin notes that it would still be useful for those who bike or walk, which “is quite common in Europe. And when you are walking or biking, often you don’t have a GPS.” But she says the team needs to come up with a way to automatically identify landmarks.

[Billy] Chen, [a researcher in the MSN Advanced Engineering group], says that Microsoft could use a list of landmarks that is already in its geospatial database, or such a list could perhaps be compiled by users.

Access to Information: California County Hoarding Map Data Ordered to Pay $500,000

Friday, October 16th, 2009

From the Article:

A California county’s three-year battle to prevent a nonprofit group from obtaining public mapping data has ended disastrously for the county after it was ordered by a court to pay the group $500,000 in legal costs.

Last February, Santa Clara County, the heart of California’s Silicon Valley, was ordered to hand over the public records to the California First Amendment Coalition for a minimal duplication fee after initially trying to charge $250,000 for the data and then appealing to the federal government to designate the data a national security secret that couldn’t be released. This week the county paid out to the coalition twice the amount in legal fees that it had once hoped to rake in as profit for the data.

[Snip]

In 2006, the coalition used the state’s sunshine law to ask for a digital, data-rich map compiled by the county. Called a geographic information system, or GIS, parcel basemap database, the map shows the boundaries of 450,000 real estate parcels in Silicon Valley, along with overlaid aerial photos, street addresses and other data.

The county demanded $250,000 for the information, along with a signed nondisclosure agreement asserting that the coalition wouldn’t redistribute it, even though other California counties provide the same data for free or charge a minimal duplication fee.

Atlanta Prepares for “Mapathon”

Thursday, October 15th, 2009

From the Article:

Atlanta, the capital of the US state of Georgia will soon be the world’s most digitally mapped city, according to organisers of a massive “mapathon”.

OpenStreetMap, or OSM, is behind the effort to produce a map more accurate than anything else on the market. In addition, all the data will be given away free for others to use. “We aim to map everything from bike paths to emergency phones and police precincts,” said Frank Howell from the Office of Research and Policy Analysis.

Online Maps + Crowdsourcing: Just How Good is Your Cell Signal?

Monday, October 12th, 2009

From the Article:

Until now, cell phone users have had no detailed and impartial way to assess and compare which network offers the best data and voice service where they use their phones.

Root Wireless Inc., a Bellevue, Wash., startup, aims to change that. Root’s colorful online map, which debuted last week on CNET.com and is currently usable only by consumers living in the eight U.S. markets analyzed so far, shows voice and data signal strength for each of the four major U.S. carriers. An intriguing plan calls for building out map coverage through 200,000 volunteers nationwide, all armed with a data-gathering app on their smartphones.

[Snip]

Initially, the Root map is accessible only through CNET.com, as part of its library of cell phone reviews. CNET isn’t promoting the map, but it’s available by clicking “check coverage” directly under the reviewed phone’s name. Checking it out is difficult, because it is currently available only within selected cell-phone reviews, and only to CNET visitors in the eight markets — Chicago, Dallas, Los Angeles, New York, Orange County, San Francisco, Seattle and Washington, D.C. — where Root has done its own mapping.

Another 12 [metro] markets are slated to be mapped by year-end: Atlanta, Baltimore, Boston, Denver, Houston, Miami/Ft. Lauderdale, Minneapolis, Philadelphia, Phoenix, San Diego, St. Louis and Tampa/St. Petersburg.

Source: MSNBC

The map provides data for AT&T, Sprint, T-Mobile and Verizon Wireless. It’s easy to move from one provider to another.

To access the map which is a beta release (remember only eight markets are currently available) head to the cell phone review section of CNET and select a smartphone. ) Smartphones are the only phones that will trigger a map link during the beta period. We’re selecting the iPhone 3GS 32GB (in white) from AT&T. Finally, look in the right hand column below the first two boxes for the clickable link, “Check your coverage area.” You should now be viewing a map. The default region on the map is Metro Seattle but simply enter a street address and/or Zip Code for one of the available metro areas and the map will change to that location. At the bottom of the map you can learn more about data collection and methodology and report descriptions.

The MSNBC article also points out that when the beta period is over (sometime in January) you’ll be able to access maps for all phones.

Finally, if you’re interested in helping Root Wireless crowd source other areas, this page is where you register.

Google Drops Tele Atlas As Provider of U.S. Maps, Company Now Creating Their Own Maps with the Help of Crowdsourcing

Monday, October 12th, 2009

Greg Sterling at Search Engine Land does a great job discussing the big news that Google’s primary map provider, TeleAtlas, has been dropped and the company is now using their own maps that were created (and will be maintained) using crowdsourcing and other sources (e.g. U.S. Census data) along with StreetView data.

We’re wondering if other data sources like Sandborn Maps will continue to be used by Google.

Tele Atlas will continue to provide maps to Google for many other countries.

On the Directions Magazine web site, Michael Jones from Google, list and discusses the large number of Google tools and services that have a geographic component.

He Writes:

I’ve been saying in keynote talks for years that users are the local experts and that a rich and accurate map of the world must therefore reflect user’s knowledge.

He Adds:

I know that users are now better served with an easily correctable, rapidly updatable, widely usable base-map built from the synthesis of hundreds of data feeds, hundreds of thousands of individual contributors, and potentially, hundreds of millions of local-expert users.

Jones continues and briefly explains how Google got the U.S. maps project started.

UPDATE (10/13): Map/GIS data experts, Joe Francica and Adena Schutzberg, from Directions Magazine have recorded an excellent podcast that discusses the changes with Google Maps in the United States. Below the podcast box, you’ll also find links to several articles. Several point out that parcel data (we don’t know the provider) is now available via Google Maps for several locations in the U.S. Be careful using the parcel data. As of today (this could change at any time), it isn’t as robust as what you find with databases that specialize in this type of data. For example, you can’t click on a parcel and find out the owner of the property and it’s impossible to determine how current it is.

Online Database: Mapping Languages in the United States and More Research Tools

Saturday, October 3rd, 2009

From the Introduction:

The MLA [Modern Language Association] Language Map is intended for use by students, teachers, and anyone interested in learning about the linguistic and cultural composition of the United States. The MLA Language Map uses data from the 2000 United States census to display the locations and numbers of speakers of thirty languages and three groups of less commonly spoken languages in the United States. The census data are based on responses to the question, “Does this person speak a language other than English at home?” The Language Map illustrates the concentration of language speakers in zip codes and counties. The Language Map Data Center provides data from Census 2000 about over three hundred languages spoken in the United States, including actual numbers and percentages of speakers. Data from the 2005 American Community Survey about the thirty languages most commonly spoken in the United States provide a snapshot of recent changes in American language communities.

This web tool allows users to map and illustrate what languages are spoken in the United States.

Begin by selecting a language and then selecting a state. A national map is also available.

Then, select one of three data points to view on the map:

+ Percentage by County
+ Number by County
+ Number by Zip Code

Users can zoom in/out and add extra data layers (e.g. county names) to the map.

At the bottom of the map there is a numerical or alphabetical listing of all languages spoken in area you’ve selected.

The Modern Language Association also provides the MLA Language Map Data Center

Here, users will find specific numbers of language speakers by:

+ US, State, Region, or Division (Pie Chart)
+ Languages by State (Ranking)
+ Languages by County (Ranking)
Researchers can also enter a city name, Zip Code or county subdivision and get back rankings.

Finally, MLA provides a map comparison tool where users can view two maps side by side.

Like the primary mapping tool, it’s possible to choose one of three data points to view on the map:

+ Percentage by County
+ Number by County
+ Number by Zip Code
