Flying Through Google Earth at Macworld

This year for Macworld I decided to create a program that allows people to "surf" any region on the Earth's surface using a Nintendo Wii Balance Board and the Google Earth API.  To do this, I used the Google Earth Browser Plug-in with a Javascript API.  The Wii Balance Board transmits the your movements to the Earth Surfer application using Bluetooth and allows you to maneuver a virtual milktruck by shifting your balance as if you were on a surfboard.

Check out the following video to see it in action:


While it's fun to use Earth Surfer, I really wrote it to inspire others to write their own programs. It's all open source using the Apache License, so you can use the code in your own programs, even commercial ones.

It is based on Thatcher Ulrich's terrific Javascript Monster Milktruck demo, which is an open source program on a webpage. I wrapped it as a Macintosh application program so I could add Objective-C.  Objective-C uses the Macintosh Bluetooth support to decode the Bluetooth packets from the Wii Balance Board. The Balance Board support is my work. I based that on DarwiinRemote, open source decoders for the Wii Remote.

Earth Surfer and its source code will be available next week on the Google Mac Developer Playground.

Google Street View helps find kidnapped Mass. child

[Cross-posted with the Public Policy Blog]

An interesting first (at least as far as we're aware): Google's Street View imagery was used by police officers to help successfully locate a kidnapped child in rural Virginia.  Nine year old Natalie Maltais, from Athol, Massachusetts, was found safely at a motel on Tuesday.  You can read more in the Worcester Telegram & Gazette.

Geotagging blog posts

As part of the Lat Long blog team, I'm naturally a big fan of both maps and blogs. Recently, the Blogger team launched a feature that combines both of these -- geotagging for your blog posts.

When you use Blogger in draft, you'll see an option below the post editor to "add location". If you know the exact location, you can simply enter the address, city, or zip code; if you're blogging about the view from the top of a mountain you just hiked or don't have a precise location, you can browse the map or turn on satellite mode and put a marker at the right spot (and the reverse geocoder will label the location for you). The geotag will appear below your published post as a link, which will open up Google Maps. The location will also be included in your blog's RSS and Atom feeds using GeoRSS.

Building a bridge in Google Earth

More than 250,000 vehicles a day zip past the largest construction project in California history. That project – the new San Francisco-Oakland Bay Bridge – is now on Google Earth, the first time a construction project has been featured. You'll be able to do things on Google Earth's Bay Bridge that would get you arrested in real life – like climbing to the top of the Self-Anchored Suspension Span's single tower, which offers breathtaking views of the Bay Area. To view the model, turn on the 3D Buildings layer in Google Earth.

The bridge is scheduled to be completed in 2013, so visitors are getting a sneak peak of this new Bay Area landmark. The solid sections of the bridge are already complete, while the transparent sections are under construction, and we will continue to update the model as the construction progresses. Now you can be among the first to "drive" across the new bridge and see a world class icon come to life.

Tracking Santa: the backstory

[Cross-posted with the Official Google Blog]

When I look back on four years of tracking Old St. Nick on Christmas Eve, I can't help but smile. The Santa tracker has really come a long way. I always thought NORAD's Santa Tracker was a great holiday tradition, but I felt like it could have been even better if people could visualize exactly where Santa was on Christmas Eve. So in 2004, shortly after Keyhole was acquired by Google, we followed Santa in the 'Keyhole Earth Viewer' — Google Earth's original name — and we called it the 'Keyhole Santa Radar.' The audience was relatively small since Keyhole was still a for-pay service at that point, and we hosted everything on a single machine shared with the Keyhole Community BBS server. We probably should have had 3 separate servers to host the Santa tracker - that first year, we had only a portion of a single machine. That night, about 25,000 people kept tabs on Santa and, needless to say, wreaked some havoc on our servers!

Over the next two years, our Santa-tracking efforts improved dramatically. By December 2005, Keyhole had become Google Earth and our audience had become much, much larger. Our 'Santa Radar' team also grew: we used greatly improved icons from Dennis Hwang, the Google Doodler, and set up 20 machines to serve the tracking information. My colleague Michael Ashbridge took over the software and more than 250,000 people tracked Santa on Google Earth that Christmas Eve. In 2006, Google acquired SketchUp, a 3D modeling software that enabled us to include models of Santa's North Pole workshop and sleigh. We also incorporated a tracking feed directly from NORAD's headquarters, and we were now displaying NORAD's information in Google Earth. That night, more than a million people tracked Santa.

In 2007, Google became NORAD's official Santa Tracking technology partner and hosted www.noradsanta.org. In addition to tracking Santa in Google Earth, we added a Google Maps tracker and integrated YouTube videos into the journey as well. Now, we had Santa on the map and on 'Santa Cam' arriving in several different locations around the world, with commentary in six different languages. The heavy traffic — several millions of users — put Google's infrastructure to the test, but with some heroic work by our system reliability engineers, the Santa Tracker worked continuously.

This year, Googler Bruno Bowden is in charge of the Santa software, and we have further upgraded our server capacity. We're hoping this version of the tracker will be the best yet. In addition to our Santa Cam footage, geo-located photos from Panoramio will be viewable in Google Maps for each of Santa's stops without a video. We've also included a few new ways to track Santa. With Google Maps for mobile, anyone can keep tabs on him from their mobile phones (just activate GMM and search for 'norad santa'). You can also receive updates from 'Bitz the Elf' on Twitter by following @noradsanta. And of course, be sure to visit www.noradsanta.org tomorrow morning at 6:00 am EST when Santa's journey begins.

Snow conditions of Alpine skiing resorts in Google Earth

It is undeniable: winter has arrived here in Europe. Piles of snow line the roads, white roofs and snowmen call for your attention. I can't help but start thinking about skiing and snowboarding.

A very easy and visual way of checking the latest snowfalls in ski resorts in the Alp regions of Austria, Germany, Italy, and Switzerland is the new "Ski resorts in the Alps" layer in Google Earth. You can find it in the Gallery folder of the layers panel under "Travel and Tourism".

All information on the ski resorts are provided by bergfex who aggregates the data from the ski resorts to make sure that you get the latest data in this layer. The icons represent the average snow depth of that area; the whiter the icon, the more snow you can expect. Check back often, as these snow depth readings are updated four times a day.

Every balloons displays useful information such as the fresh snow depth from within the last 24 hours (on the mountain and also in the valley), the altitude of the skiing area, the length of the slopes, useful phone numbers, and much more!

Now use Google Earth to get the latest info and then get outside to enjoy the snow, the real stuff, on-site!

Where does our oil come from?

[Cross-posted with the Google.org Blog]

There’s a great deal of talk about the high cost of oil and the billions of dollars that the US and other oil-importing nations spend each year to buy oil. As part of the Google.org Geo Challenge Grants Program, Rocky Mountain Institute (RMI) has created a map of US oil imports by country since 1973. By clicking on the green light to play, you can see the countries supplying oil to the U.S. (either in terms of barrels or dollar value) and how our imports have changed over the last 35 years. The thicker the line in the map, the more oil produced or imported. While this map highlights data on United States oil imports, the picture is similar for every oil-importing country in the world.

The map highlights 5 eras of oil consumption, from the oil shocks of the 1970s to the price collapse in the 1980s to recent events including Hurricane Katrina and gas approaching $5 per gallon before retreating rapidly recently. (You can see these selections by clicking on the buttons below the map on the RMI website.) One interesting time period is from 1982 to 1985, when low prices caused oil imports from the Middle East to decline to very low levels.

The map also looks at potential oil from offshore drilling and exploration of the Alaska National Wildlife Refuge (ANWR). The screenshot below illustrates the impact of off-shore drilling. With the map zoomed or ‘drilled’ 3-5 levels down and centered near Alabama (and the map pushpin that represents offshore), check out the very thin line that shows the potential peak production of 220,000 barrels per day. The lines represent estimates of production in 20-30 years, and even with this very long timeline, the amount of oil that could be generated from offshore drilling is miniscule compared to our oil needs today.

Both Google and RMI are working hard to help create a future where we are not reliant on daily imports of millions of barrels of oil that pollute our atmosphere and risk our national security.

Today, along with the Brookings Institution, RMI is hosting “The Oil Solutions Initiative” a summit to identify solutions to break America’s dependence on oil, with Google in attendance. In 2004, RMI’s Chief Scientist, Chairman and Co-founder Amory Lovins and a team of RMI collaborators drafted Winning the Oil Endgame (PDF of the book) - a roadmap for the United States to get completely off oil by 2050.

Google.org’s RechargeIT initiative is driving toward the commercialization of plug-in vehicles that can wean the US off gasoline. In our Clean Energy 2030 Plan we show that increasing conventional automobile mileage, deploying millions of plug-in hybrids and accelerating the turnover of the fleet would reduce oil consumption by 51% by 2030. That decrease would have an even larger effect on oil imports because we produce about one-third of our oil in the US. Google and RMI have worked together on a number of projects including RMI’s “Smart Garage” Charrette, a summit to identify the barriers and breakthroughs needed to electrify the U.S. auto fleet.

While oil prices have declined rapidly over the past five months, most people expect oil prices to remain high into the near future. When asked whether or not the drop in oil prices reduces the need to act, President-Elect Barack Obama responded that we go from “shock to trance” and as a result “never make any progress.”

If you are a non-profit with a great idea like this one, please consider applying for funding to develop your project. We are currently accepting applications for the December 22, 2008 deadline.
