Recently we sent our Street View cars driving through the historic seaport town of Kaliningrad (the modern name for Königsberg) in Russia as part of our quest to keep Google Maps comprehensive, accurate and useful. While there, we were reminded of a classic mathematical problem: the Seven Bridges of Königsberg.

The mathematical problem posed an interesting challenge: find a route through Kaliningrad—which was once separated by the Pregel River—by crossing each of the seven bridges in town. The catch? One could only cross each bridge exactly once.

In 1735, Leonhard Euler, one of the most prolific mathematicians of all time and our recent Doodle subject, concluded that there was no solution to the problem because it was impossible to find a route that would cross each bridge only once. This famous problem and Leonhard Euler’s non-resolution paved the way for important discoveries in the field of mathematics including graph theory and topology.

Fast forward 278 years to today where we still rely on Euler’s findings to calculate optimal driving routes for our Street View cars. We use sophisticated algorithms, based on graph theory, to determine the best route through a city or town—helping us capture all the images we need in the shortest amount of time. Though these algorithms are complex, in simple terms, it’s equivalent to solving the problem of drawing a house without lifting your pen and never going over the same segment twice. Like this:

While the bridges of Königsberg may be one of Kaliningrad’s most famous landmarks, you can also explore other parts of this historic town with Street View—including the oldest building in the city, the Juditten Church, which was built before 1288, and King’s Gate, one of the city’s original six gates built during the 19th century.

In other words, leave the mathematics to the mathematicians and just enjoy the scenery with Street View!

Today is International Dance Day, a celebration of a universal art form that spans cultures and countries. But dancing isn’t just limited to holidays. Since 2003, Matt Harding has famously been dancing his way across the globe with people from all walks of life and sharing to millions on his YouTube channel. His mission is simple: Dance. Dance with everyone. Dance everywhere. Dance to spread joy.

Matt’s journey began with a serendipitous, single dance step in Hanoi. While traveling through Southeast Asia, his friend encouraged him to dance for the camera—and he just kept dancing. At first, he was amused by the idea of capturing himself dancing in front of famous landmarks and in famous cities around the world. Since then, Matt’s videos have evolved beyond a single man dancing; his videos now focus on individuals that gather together to share in the fun of dance, as you can see in his 2012 YouTube film.

The joy that goes into Matt’s work is apparent—and well documented. However, there’s also a fair amount of planning involved to choreograph his efforts. Matt relies on Google Maps for comprehensive, accurate and useful tools to execute and track his steps.

Before he sets off on each adventure, Matt uses Google Maps to scout various locations. Using Street View and photos in Google Maps, he finds landmarks and points of interest around the globe that are prefect dance spots. For instance, he came across Piazza del Popolo while exploring Rome with Street View. These tools come in handy to help Matt choose a backdrop to highlight his assembly of exuberant, local dancers.

Scouting is only part of the process. Once Matt has coordinated a group in a city, he helps everyone get to the designated destination by creating a customized My Map and sharing it with the participants so they can easily navigate to the planned meetup location. The end result is something everyone around the world can relate to.

Keep dancing!

Have you ever found yourself standing on the western bank of the Chao Phraya river in Bangkok, looking for a way to get across to the Grand Palace and the Temple of the Emerald Buddha? Or perhaps you’ve spent time scouring a map of Jakarta to find Indonesia’s famous National Monument. In order to make it easier for locals and visitors alike to find what they need and get to where they want to go, today we are publishing more comprehensive and accurate maps for Thailand and Indonesia.

These updated maps are part of a project called Ground Truth that began in 2008 as part of our ongoing quest to provide people everywhere with the most comprehensive and accurate maps. Through this project, we use high-quality map data from authoritative sources around the world and then apply a mix of advanced algorithms, supplemental data (including satellite, aerial and Street View imagery), and human input to help create a map that mirrors the real world as closely as possible.

For example, the updated map for Thailand now provides more comprehensive information about the Bangkok city center shown below.  So next time you happen to find yourself needing to cross the Chao Phraya River, you’ll be able to see that many ferry routes across the river are now mapped in greater detail, with route names shown and piers clearly marked. You can also pinpoint nearby points of interest, such as the Grand Palace and other sites like Wat Pho (the Temple of the Reclining Buddha).

We’ve also added many other kinds of new information to the map, including improved local-language labels and detailed coverage for prominent places like universities and hospitals. For example, the new map shows building outlines, department labels, and colored highlighting for campus grounds at the Gadjah Mada University, one of Indonesia’s largest universities.

Today’s update also makes our maps more comprehensive by bringing more of Thailand and Indonesia’s natural geography online for everyone to see. The country of Indonesia spans more than 17,000 islands; with today’s update, many of these islands — including Komodo Island, home to some world-famous dragons — are appearing on Google Maps for the first time.

Of course, the world is always changing, and we want Google Maps to change with it. If you happen to notice something on the map that needs updating, you can let us know by clicking the “Report a problem” link, which is visible today  in the lower right corner of your screen when you’re browsing the map of Thailand or Indonesia.  We’ll review your comments and make the appropriate changes to the map; you’ll often see the updates take effect within just a few minutes or hours of the time we verify your feedback!

Today’s updated maps are just another milestone on our never-ending journey to bring you the most accurate and comprehensive maps of the entire world. We hope Google Maps will help you explore your way through Bangkok, Bali, Bandung, and more!

Whether you’re planning a summer vacation to visit the Colosseum or exploring potential neighborhoods for your next move, Street View gives you instant access to the places you want to see — even before you leave the house. We launched Street View in 2007 in five U.S. cities to give you what we called a “feet on the ground” experience and have since been growing the program to make it more comprehensive, accurate and useful for everyone.

Today, we’ve reached 50 countries with the launch of Street View in Hungary and Lesotho and are significantly expanding our coverage in Poland and Romania, among other locations around the world. This is also the largest single update of Street View imagery we’ve ever pushed, including new and updated imagery for nearly 350,000 miles of roads across 14 countries.

Now you can take a virtual stroll through the historic center of Budapest, right along the Danube (the river that carves the city in two). See the Hungarian Parliament building or the famous Chain bridge.
