Attending Press Announcement for New Google Earth

April 17, 2017

As was mentioned last week by dozens of media outlets, Google sent out press invitations to an event for April 18th to roll out a “brand new Google Earth” experience. I will be attending and will report on this long-awaited event!

New Google Earth

Google didn’t say much in their invitation, and we have yet to receive any press material. But, we believe this announcement will describe a new version of Google Earth that will work on desktop and mobile platforms. Our guess is that there will be a web based version on desktop OSes – most likely with WebGL, which is the predominant standard being used for graphics intensive web apps today. If it is browser based, it means more OS platforms will have access to Google Earth content. We’ll have to wait and see whether the new application will have new features beyond the current Google Earth, or a subset.

Google Earth VR Update?

There may also be announcements about new features/versions of the Google Earth VR application which was released last November for HTC Vive VR platform. There have been no significant updates to that application, and we expect Google is likely to release an Oculus Rift version (since they recently released a Rift Touch version of their Google Tiltbrush VR paint application for the HTC). Or, we may see a version for Google’s Daydream VR platform – although that will be a less-capable version since Daydream VR doesn’t currently support HMD tracking or full 3D controllers.

Other New Content

It’s also possible there will be an unveiling of more Google Earth 3D imagery (aireal imagery converted to 3D data using photogrammetry), and content especially geared towards the new versions. Google has a history of doing this for major updates to Google Earth. There was less 3D imagery added in 2016, but they may have been saving up for this announcement.

As long time fans of Google Earth, we are going to be watching closely to see if this new Google Earth will support popular features from the more than 12 year legacy of Google Earth desktop applications. Keep following Google Earth Blog during, and after, the event for all the latest news and analysis. We have been reporting on Google Earth applications and content for nearly 12 years now.

The New Google Earth is finally coming April 18

April 13, 2017

Google has sent press invitations announcing a first look at the “brand new” Google Earth on April 18. Just in time for Earth Day (which is April 22). Anyone reading this blog, which has been a fan blog about Google Earth since its inception in 2005, knows we have been waiting anxiously for a new version of Google Earth. It’s been five years since the last major release for Google Earth. We have been worried about the future of one of the world’s most popular applications during the past decade. But, Google has been promising us a new version is coming. They talked about it two years ago for Earth Day 2015, as the 10th anniversary of Google Earth approached. We can’t wait to see it.

Google Releases Google Earth VR for HTC Vive

November 16, 2016

Google has released a free new version of Google Earth on a totally different computing platform: Virtual Reality (VR). Google imaginatively calls it Google Earth VR. Specifically, for now, this version is for the HTC Vive which is the only consumer platform with dedicated 3D controllers for interacting in VR. Download link for GEVR (from the official Steam page). You can watch the Google Earth VR demonstration video from the Google announcement below:

Based on my reviewing it today, Google is taking great advantage of VR with the new version. You can view the Earth, and all its places, in an entirely different perspective. Because, now Google Earth’s 3D content is fully stereoscopic 3D, and immerses you in cities, valleys, mountains, etc. You can use the 3D controller to fly yourself around, or drag the sun to get a different sun angle, or see the stars at night above your chosen landscape or city. Google has chosen to give you a non-human scale, so when you are viewing places like cities – you feel like a giant who can reach out and hug a skyscraper, or give a hug to Half Dome or the Matterhorn. Since the Vive allows you to move around your room, you can literally walk around mountains, canyons, buildings, and more. [EDIT: It is possible to change setting in the menu options so you can feel more human scale sized].

Google starts the program by offering you a basic tour which flies you to several well-known locations on Earth. The first time you experience it, you will probably have a strong “Wow” feeling as the scenery is stereoscopic 3D, and you can look in any direction. I sure had that reaction myself! In addition, Google uses 3D audio and music for the tours. In some places you hear city street sounds, in one you hear the church bells of a nearby cathedral, and in nature shots you might hear some wind or car noises from a nearby highway. It definitely adds to the realism of the scenes.

After the tour, you end up with a full view of the Earth in space (an amazing experience), and are then given tips on using the controllers to drag the Earth, and fly down to see whatever place you like. You can also pop up a menu that gives you choices of other tours, and selections of cities and places you might want to visit. The controls also enable you to take screenshots. One of my favorite features is that you can point the controller at the sun and drag it across the sky, or below the horizon to make the sky switch to night (where you will see the stars and milky way in all its glory).

There’s more to learn about the interfaces than you might first realize. One surprise I got is that if you point at the controller in one of your hands (the one which shows a globe with the current position) with the other controller, the globe grows to a larger version of the Earth with a pin showing your current position. You can then use the other controller to rotate the earth, and point at a rough position on the globe and drop a new pin to fly to that location. This is a very cool feature and immediately reminded me of the scene in the book “Snow Crash” by Neal Stephenson, that one of the original developers of Google Earth said was originally an inspiration for the first version of our favorite program.

It’s great to see Google finally release something new and exciting for Google Earth. A new version of Google Earth has been rumored for over two years for the desktop/mobile platforms that will be a complete re-write. But, we have yet to see even a test version in the wild for the new Google Earth. So, we are still waiting.

Since I’ve been spending the last year working with VR technologies, I’m particularly glad to see Google Earth for this new exciting immersive platform. They have released the program for the HTC Vive via the Steam gaming platform (the Vive was largely developed by the makers of Steam at Valve Corporation), which is the biggest platform for VR content. Considering the cost for HTC Vive ($800 – not including a beefy PC and graphics card), and it having been released less than a year ago, there are estimated to be fewer than 300,000 Vive owners at this point. Still, for Google to release now is a big statement about the future of VR. I suspect versions for Oculus Rift and Sony Playstation VR, and quite probably for Google’s new Daydream View VR platform.

Some other observations about Google Earth VR:

1) They use a “comfort mode” technique (dwhich you can turn off in the menus) which shrinks your view while you are “flying” in Google Earth. This minimizes your peripheral vision and thereby helps lower visual-induced motion sickness. It’s actually quite effective. I tried turning it off in the menu and definitely felt less comfortable when flying inside VR. Once you stop moving, you get the full 360 panorama back, and you can still swivel your view while flying.

2) If you are looking to buy the Vive, HTC is now bundling Google Earth VR with it. Which is kind of silly when you consider its a free app, so it’s not exactly a value add.

3) ~~An important note is that the Google Earth 3D terrain is simplified in in detail for GEVR compared to what’s available in the desktop version of Google Earth.~~ [EDIT: Turns out GEVR made me realize Google at some point reduced 3D terrain fidelity for some places where formerly they had higher resolution data. After checking the desktop I found both GEVR and desktop GE now have lower resolution in formerly higher resolution locations.]

4) If you are standing in your room with your Vive (as most Vive users do), then you will notice you never are lower than about 50 meters off the ground. If you want to look closer at the ground, you can get your head closer to the ground (where you are standing) and look closer. This might not be obvious at first, so I thought I would mention it.

Space Engine – to Infinity and Beyond

February 17, 2016

I still remember the first time I used Google Earth and how my sense of wonder grew as I realized the amazing capabilities of the program to portray our planet Earth at new levels of detail with a huge source of data both in aerial imagery, but also in 3D. It has been a long time since I found a program which generated the same sense of wonder. Until now.

I recently ran across an application called Space Engine which was reported to produce amazing visualizations of space and let you tour not only our solar system and nearby stars, but also stars throughout the Milky Way. Even better, the developer uses an algorithm to create planets, moons, asteroids and comets for as many star systems as astronomers currently believe exist, throughout our galaxy. Beyond that, Space Engine generates them for galaxies throughout the universe as we know it. So, you can literally visit trillions upon trillions of stars and planets (if you had enough time!) for endless galaxies. When you visit a planet, moon or asteroid’s surface, the program procedurally creates 3D terrain and textures to make the surface appear more realistic. To put this in perspective, this program lets you have an entire Universe to explore inside your own computer. Wow! However, it does require a relatively powerful desktop computer (or gaming laptop) with a beefy video card to run well (see the minimum specs in the download link at his web site).

My feeling was just as enthusiastic viewing Space Engine as the first time I saw Google Earth. What really amazed me was seeing the beauty of our universe when portrayed using more current graphics technology, and the endless sense of exploration to discover new worlds. Space Engine allows you to experience the awe and wonder of the Universe and capture your memories to share with others.

Space Engine uses data from dozens of astronomical databases to accurately portray the physical characteristics for all the known systems. It also extrapolates the characteristics for stars and planets beyond to fill our galaxy and other galaxies based on theoretical compositions. You can easily see the physical characteristics (size, mass, gravity, atmosphere, temperature extremes, and whether a planet could support life). In a sense it is more of a sandbox simulation, or a game, than a mirror of our universe.

It’s important to note that your movement in Space Engine isn’t limited by silly physical laws like the speed of light, so you are able to travel to other systems throughout the Universe in very reasonable amounts of time. If you were limited to our current technological and scientific abilities, and our understanding of physics (not being able to travel faster than the speed of light), it would take decades or centuries to even reach the nearest star systems to Earth.

I had plans for creating my own video demonstration of this application. But, I keep getting engrossed in the program. So, I’m sharing one of several YouTube videos about Space Engine to give you a taste of the experience. If you have dreamed of space flight, like I have, then you will most likely have the same reaction of awe and wonder that I do every time I use Space Engine. Watch this video demonstration by a gamer called Obsidian Ant who is just as amazed:

To make Space Engine more like a game, the developer has chosen to allow its users to add space ships and controls so you can fly through space as if you were an explorer and visit places. You can really get a sense of dimension when you compare objects next to a spaceship. The developer has even added support for virtual reality by supporting the Oculus Rift – so you can really immerse yourself in this universe.

Like with Google Earth, Space Engine lets you click at a place (a star or other object you see in the background) and see information about it. Then, you can click a button and choose to simply fly to that location and get a closer view. Using various controls (including that Space Navigator, mouse, keyboard, joystick or even flight sim controls) you can easily move around the various astronomical objects and get better views. You can even land on them. I find myself regularly taking screenshots (like photographs) of the amazing views I see in this program! I have long used space art as a desktop background on my computers, and now I have an endless supply of views that are as good or better than those I’ve used before. If you search Google Images, you can find many thousands of screenshots from this program on the Internet.

Also like Google Earth, you can save a place you are viewing like a placemark and visit again at a later time, or share it with your friends. So, in many ways, Space Engine has abilities like Google Earth, but extrapolates its range to the whole universe, not just our home planet. But, Google Earth remains the king when it comes to portraying our home planet (both in terms of realism, but also in terms of the amount of data about Earth). Google Earth’s Mars and Moon modes also have far more data than Space Engine about those bodies. Space Engine has prettier views though, because it uses more recent graphics technologies and isn’t limited to near-surface viewing like Google Earth.

What’s really amazing about Space Engine, is that it was created, and continues to be developed, by a single person. Vladimir Romanyuk is a software engineer who lives in Russia. He has not only developed this application, but also architected his own universe using his knowledge of software and astrophysics. He does get help from an active community for space ship models, feedback, and contributions towards planetary models and textures. His software is not officially released yet – latest beta version is 0.9.7.4. But, judging by his fans, and my experiences, this freely available program is getting close to ready for broader use. According to his community forums he is planning to release a version of Space Engine for the Steam game platform soon which will greatly increase its exposure.

I should mention that there are some comparable commercial space games out there which already have a more robust gaming architecture for space travel with thousands of active users. The most popular and comparable one I’ve seen is Elite: Dangerous. Space Engine exists, in part, because of the much older pioneer in this genre of a free program called Celestia which also let you explore space and even allows people to create educational tours. I used Celestia many years ago as well and mentioned it in early days of Google Earth Blog posts, but the application has not been worked on for a long time. If you don’t have a fast enough computer for Space Engine, you can probably download and run Celestia (Windows, Mac, and Linux) and enjoy its more limited capabilities.

Many thanks to Vladimir for his fantastic work with Space Engine. He has done something I always thought would be the next step after Google Earth and even discussed with Google. I wish Vladimir the best success as he introduces his universe to a wider audience and continues to astound us with future features and data. His application right now is a real joy to experience. It may be a little tricky to learn the more advanced features, but the Space Engine forums can help you figure things out. Space Engine only runs on Windows right now, but he’s asking for donations to help him add new features and versions for Mac and Linux. He has recently uploaded his latest version to 0.9.7.4 RC1 (release candidate 1). Download here (note the file size shown on the page).

All of the screenshots in this post came from Space Engine with permission from it’s developer.

New Google Earth Flight Simulator Tips and Video 2015

December 15, 2015

Did you know Google Earth has a free built in flight simulator and you can fly all over the world? It has been there since 2007, and in the meantime computers have gotten way faster and the data has gotten better. In some ways, its the best simulator you can fly!

Shortly after the flight simulator mode was first released as a surprise easter-egg by Google, I produced a video for this blog showing off the feature and how you could fly in Google Earth. But, it wasn’t possible to do an HD resolution video at that time and the content for the city I flew over was much lower resolution compared to today’s new Google Earth 3D imagery. I’ve been meaning to do an HD video for a long time. Check out this super HD video below – and make sure you view it FULL-SCREEN. You’ll be amazed Google Earth can do this! The video will give you all the basics on how to fly, but I’m sharing more details and tips below the video. This video was captured at 2560×1440 at 60FPS, so it really shows off the awesome 3D data Google has been putting in Google Earth the last few years.

GE Flight Simulator Tips

Inside Google Earth, look for the menu choice under the Tools menu called Enter Flight Simulator…. A window will appear (see below) which lets you choose which plane you want to fly and where you want to start. To quit the simulator hit the Exit Flight Simuator button, or the ESC key on the keyboard. There’s also a keyboard shortcut “CTRL-ALT-a” that will start the mode immediately.

Flight Sim Requester Window in Google Earth

Tips for beginners – You should first read the Help on the startup window, or simply go to this Google web page to learn the basic controls for flying. More keyboard shortcuts can be found on this site.
1. Start up the flight simulator as described above. I recommend you choose the SR-22 plane to start (it is a much slower plane than the F-16, and will help you learn the controls). Choose an airport, but be aware most of the provided airport choices have changed in the years since the simulator was added. Better to put yourself on a runway as shown in the video. If you don’t have a joystick, you can’t select one. Don’t worry, you can use the mouse/trackpad to fly. Next hit Start flight.
2. You will see the HUD (Head Up Display) in green (click here for a guide to the HUD indicators). Make your window dimension roughly square (otherwise you may not see all of the HUD display elements, although this problem was fixed in later versions of GE).
3. To get started, hold down the Page Up key briefly (this will add power to your plane). The throttle indicator is on the lower left (triangle should be at the top for full throttle).
4. To control your direction on the ground, use the comma and period keys on your keyboard to apply left and right brakes. Just touch them briefly to change direction left and right. Holding them down will slow you down and that is used for landing.
5. Important tip – mouse control – it’s best to use the mouse to control the plane (unless you have a joy stick). I wouldn’t bother with trying to fly with the keyboard. Simply click the mouse once in the center of the view and you should see your cursor change to a “+” sign. Don’t move your cursor outside the window or you will lose control! The mouse will only control your plane in the air, and if the cursor is inside the Google Earth window.
6. Taking off – Once your plane is going faster down the runway, try moving the mouse back slightly from center. If you’re going fast enough you should take off. Remember: just make small motions with the mouse close to the center of the screen. Once you have the wings level, put the mouse in the center. A lot of first time fliers have a tendency to over correct.
7. To make a turn – move the mouse slightly to the right or left and when your plane is banked, pull back slightly. When you’ve made the turn you want, push the mouse back to the center then the other direction to tilt the plane back to level. Then re-center the mouse cursor.
8. Pausing – If you want to stop for a moment, simply hit the SPACE key on the keyboard and it will pause the simulator. Hit SPACE again to resume. You can look around with the CTRL and arrow keys. Re-center your view with the V key.
9. 3D Buildings – Turn on the 3D Buildings layer before you start the simulator to see the 3D city data.
10. Start higher – Position your view in Google Earth in the normal mode so you are at a high altitude above ground. Tilt your view so you are looking at the horizon. Then restart the flight simulator mode (use Tools->Enter Flight Simulator… menu, or the keyboard shortcut CTRL-ALT-A) so you can choose what plane to use, and other options. Choose Select your start position->Current view in the window, and then choose Start flight. You should add power by hitting the Page Up key after starting it up. Now you can practice flying a while before you hit the ground!
11. Landing – it is possible to land the plane. You can watch the video above for ideas and tips on landing the SR22. For landing with the F16 jet, here’s a recent video a reader shared showing him landing it.

Get out there and try flying around! You’ll be amazed to find out how smooth Google Earth can be for exploring the world. I recommend you try areas like the Swiss Alps, the Rocky Mountains of the US, or the New Zealand mountains for some really nice terrain. All of these areas have high resolution terrain available in Google Earth. And Google Earth has added many cities with detailed 3D data, it’s definitely worth exploring to see your favorite cities.

The skies are always clear in Google Earth – so, have fun!

If you are a flying enthusiast, you might want to buy a real flight simulator. My current favorite is Microsoft Flight Simulator X (or FSX) only available now through Steam online. It works quite well on current desktops/laptops. You can find out more here (click on the image):
