The quest for the perfect map

(Cross posted from the Official Google Blog)

For the last decade we’ve obsessed over building great maps for our users—maps that are totally comprehensive (we’re shooting for literally the whole world), ever more accurate and incredibly easy to navigate.

Comprehensiveness

It’s a pretty limited search engine that only draws from a subset of sources. In the same way, it’s not much of a map that leaves you stranded the moment you step off the highway or visit a new country. Over the last few years we’ve been building a comprehensive base map of the entire globe—based on public and commercial data, imagery from every level (satellite, aerial and street level) and the collective knowledge of our millions of users.

Today, we’re taking another step forward with our Street View Trekker. You’ve seen our cars, trikes, snowmobiles and trolleys—but wheels only get you so far. There’s a whole wilderness out there that is only accessible by foot. Trekker solves that problem by enabling us to photograph beautiful places such as the Grand Canyon so anyone can explore them. All the equipment fits in this one backpack, and we’ve already taken it out on the slopes.

Accuracy

The next attribute map makers obsess over is accuracy. We still have a way to go because the world is constantly changing—with new houses, cities and parks appearing all the time—it’s a never ending job. But by cross-checking the data we have, we can significantly improve the accuracy of our maps. Turns out our users are as passionate about the quality of Google Maps as we are, and they give us great feedback on where we can do better. We make thousands of edits a day based on user feedback through our Report a Problem tool and via Map Maker, which we launched in 2008. Today we’re announcing the expansion of Map Maker to South Africa and Egypt, and to 10 more countries in the next few weeks: Australia, Austria, Belgium, Denmark, Finland, Liechtenstein, Luxembourg, New Zealand, Norway and Switzerland.

Usability

The final element of the perfect map is usability. It’s hard to remember what digital maps were like before Google Maps went live in 2005, and the huge technological breakthroughs that transformed clicking on arrows and waiting, to simply dragging a map with a mouse and watching it render smoothly and quickly. Plus, we added one single search box. Today we have thousands of data sources that feed into our maps making them a rich and interactive experience on any device—from driving directions to transit and indoor maps to restaurant reviews.

People have been asking for the ability to use our maps offline on their mobile phones. So today we’re announcing that offline Google Maps for Android are coming in the next few weeks. Users will be able to take maps offline from more than 100 countries. This means that the next time you are on the subway, or don’t have a data connection, you can still use our maps.

The next dimension

An important next step in improving all of these areas—comprehensiveness, accuracy, and usability of our maps—is the ability to model the world in 3D. Since 2006, we’ve had textured 3D buildings in Google Earth, and today we are excited to announce that we will begin adding 3D models to entire metropolitan areas to Google Earth on mobile devices. This is possible thanks to a combination of our new imagery rendering techniques and computer vision that let us automatically create 3D cityscapes, complete with buildings, terrain and even landscaping, from 45-degree aerial imagery. By the end of the year we aim to have 3D coverage for metropolitan areas with a combined population of 300 million people.

I have been working on mapping technology most of my life. We’ve made more progress, more quickly as an industry than I ever imagined possible. And we expect innovation to speed-up even more over the next few years. While we may never create the perfect map … we’re going to get much, much closer than we are today.

The smartphone growth is global

Last October, we launched Our Mobile Planet, a resource enabling anyone to visualize the ways smartphones are transforming how people connect with information, each other and the places around them.

Today, we’re releasing new 2012 research data, and the findings are clear—smartphone adoption has gone global. Today, Australia, U.K., Sweden, Norway, Saudi Arabia and UAE each have more than 50 percent of their population on smartphones. An additional seven countries—U.S., New Zealand, Denmark, Ireland, Netherlands, Spain and Switzerland—now have greater than 40 percent smartphone penetration. In the U.S., 80 percent of smartphone owners say they don’t leave home without their device—and one in three would even give up their TV before their mobile devices!

We conducted this research to help people to better understand how mobile is changing our world. You can learn about mobile-specific usage trends, use this tool to create custom visualizations of data and more. There’s plenty to discover in the latest research—to dig into new survey data about smartphone consumers in 26 countries from around the world, read our post on the Google Mobile Ads blog or visit http://thinkwithgoogle.com/mobileplanet.

A tribute to Bob Moog

In the mid-1960s, Dr. Robert Moog unleashed a new universe of sounds into musicdom with his invention of the electronic analog Moog Synthesizer. The timbre and tones of these keyboard instruments (true works of art in and of themselves) would come to define a generation of music, featuring heavily in songs by The Beatles, The Doors, Stevie Wonder, Kraftwerk and many others.

When people hear the word “synthesizer” they often think “synthetic”—fake, manufactured, unnatural. In contrast, Bob Moog’s synthesizers produce beautiful, organic and rich sounds that are, nearly 50 years later, regarded by many professional musicians as the epitome of an electronic instrument. “Synthesizer,” it turns out, refers to the synthesis embedded in Moog’s instruments: a network of electronic components working together to create a whole greater than the sum of the parts.

With his passion for high-tech toolmaking in the service of creativity, Bob Moog is something of a patron saint of the nerdy arts and a hero to many of us here. So for the next 24 hours on our homepage, you’ll find an interactive, playable logo inspired by the instruments with which Moog brought musical performance into the electronic age. You can use your mouse or computer keyboard to control the mini-synthesizer’s keys and knobs to make nearly limitless sounds. Keeping with the theme of 1960s music technology, we’ve patched the keyboard into a 4-track tape recorder so you can record, play back and share songs via short links or Google+.

Much like the musical machines Bob Moog created, this doodle was synthesized from a number of smaller components to form a unique instrument. When experienced with Google Chrome, sound is generated natively using the Web Audio API—a doodle first (for other browsers the Flash plugin is used). This doodle also takes advantage of JavaScript, Closure libraries, CSS3 and tools like Google Web Fonts, the Google+ API, the Google URL Shortener and App Engine.

Special thanks to engineers Reinaldo Aguiar and Rui Lopes and doodle team lead Ryan Germick for their work, as well as the Bob Moog Foundation and Moog Music for their blessing. Now give those knobs a spin and compose a tune that would make Dr. Moog smile!
