The seafloor in Google Earth

More than two-thirds of Earth is covered by oceans. If you drained all of that water away, you’d see huge basins that have never been explored, an undiscovered planet in our own backyard.

Today is the three year anniversary of an explorable ocean seafloor in Google Earth. We just released a major update to our global underwater terrain dataset, called bathymetry, from the Scripps Institution of Oceanography, in partnership with NOAA, the US Navy, NGA, and GEBCO (with major contributions from IFREMER and IBCAO).

The update covers ocean topography from all over the globe and reveals our most accurate view of the seafloor to date. This new detail comes from spacecraft measurements of bumps and dips in the ocean surface as well as shipboard soundings from surveys carried out by over 40 countries. With this update to ocean terrain data in Google Earth, 15 percent of the seafloor is now available at 1 km resolution.

You may remember a Sun article reporting the discovery of a street grid where it’s believed the lost city of Atlantis would have been located off the West Coast of Africa. The discovery turned out to be a data artifact related to the way data was collected from a ship sailing back and forth to survey an unknown area. This recent seafloor update has been improved to blend better, and “Atlantis” has again disappeared into legend.

Previous terrain data showed what appeared to be a city grid on the ocean floor (left), which was confused for the lost city of Atlantis. Updated data more accurately reflects the seafloor terrain (right).

Another place you’ll notice an improvement in the ocean terrain data is the Mediterranean Sea, particularly south of Cyprus, where the boundary between the Eurasian and Arabian plates is now more clearly defined.

Our last example shows improvements to the land-sea mask along the coastline of Guam. You’ll notice a dramatic improvement in the resolution of both the coastline and neighboring Mariana’s Trench, the deepest trench in the world.

In order to make this update possible, our partners at the Scripps Institution of Oceanography at UCSD have curated 30 years of data from more than 8,000 ship cruises and 135 different institutions. If you’d like to get a closer look at these changes, watch our video tour of this new terrain.

We hope you enjoy diving deeper than ever in Google Earth!

Very important update for SketchUp 8

In the world of software, the designation “M2” refers to “Maintenance Release #2”. Maintenance releases are mini-versions that come out between major updates. They aren’t really about flashy new features; they’re more like tune-ups for your car; squeaks and rattles get fixes, tires are rotated, fluids are changed. You get the picture.

It’s been a few months since we released M1; since then, we’ve collected a fresh batch of performance tweaks and bug fixes—over 150 of them, in fact. M2 is a free update for all users of SketchUp 8 and SketchUp Pro 8 in all 12 languages. The best way to get it is to open SketchUp and do this:

Windows: Choose Help > Check for Update
Mac: Choose SketchUp > Check Web for Update

Having stated that maintenance releases aren’t always flashy, we couldn’t resist adding a few shiny, new things that we think you’ll appreciate:

Better Ruby Script Installation

We’ve had a way for other folks to build SketchUp plugins and extensions for years. Anyone with coding skills can use the Ruby API (application programming interface) to whip up new tools that they can distribute any way they like. People have created thousands of great scripts—we consider the API one of the most useful things we’ve done.

The tricky part has always been teaching SketchUp modelers how to install and access the Ruby scripts (Rubies) that they want to use. Adding a sophisticated Ruby used to involve finding a specific folder on your system and putting a bunch of files in all the right places. Try explaining how to do that to your boss.

The Extensions panel in SketchUp Preferences has a new button…

 

In SketchUp 8 M2, we’ve added two features that should make using Rubies a whole lot easier: The first is a new button on the Extensions panel in SketchUp Preferences. Clicking it lets you install any properly-configured “.RBZ” (ruby zip) file, which puts the needed files into the correct spot, without having to dig around in your computer’s file system. It’s simple, but huge. We’ve also added a lightweight set of “hooks” in the API that should help scripters build their own script-management tools.

Better COLLADA

All versions of SketchUp 8 can read and write COLLADA, a 3D file format that works with lots of other 3D software. It’s managed by the Khronos Group, an industry consortium that decides which features COLLADA should support. As of M2, SketchUp’s import/export support for COLLADA is now compliant with over 90% of the official Khronos compatibility test suite, only leaving out support for animations and shaders—neither of which can be authored in SketchUp anyway.

We think you’ll like SketchUp 8 M2’s ability to seamlessly import and export clean and compliant COLLADA geometry. One particular thing to note: SketchUp now preserves texture names in exported files. This makes it easier to work with COLLADA files in 3rd party rendering tools.

Advanced Camera Tools included in Pro

Back in March, we announced the Advanced Camera Tools for SketchUp Pro 8. The ACTs let set designers, cinematographers, storyboard artists and other people in the entertainment industry work with simulated real-world cameras in their SketchUp models. Until now, the ACTs were a separate plugin that you had to install. In M2, they’re built right into every copy of SketchUp Pro 8.

More Straightforward Pro Trials

After you download and install SketchUp Pro, you can try all of the Pro features for 8 hours (of use) before deciding to buy a license. Up until now, we’ve simply switched off the Pro stuff if you don’t enter a license after the trial period. Effectively, Pro reverted to being just like regular ol’ SketchUp.

The problem was that lots of people didn’t realize that they weren’t actually running Pro anymore. Even worse, folks who had bought Pro licenses and had forgotten (or otherwise been unable) to activate those licenses were missing out on all the great stuff they’d paid for. Our Pro Support team has been fielding dozens of “Why can’t I import a CAD file?” questions per day. It’s been a bit of a mess.

Starting with SketchUp 8 M2, the SketchUp Pro Trial will no longer revert to “free mode” when the trial period expires. A separate version of SketchUp will still be available to download for free, but SketchUp Pro will require a valid license file to run after your trial period has expired.

Mac OS 10.7 Compatibility

Users of Apple’s latest operating system, take note: SketchUp 8 is fully compatible with your hardware. And I ain’t lion. Rawr.

Google Plugin for Eclipse 2.5

Since Google added SQL support to App Engine in the form of Google Cloud SQL, the Google Plugin for Eclipse (GPE) team has been working hard on improving the developer experience for developing App Engine apps that can use a Cloud SQL instance as the backing database.

They are pleased to announce the availability of Google Plugin for Eclipse 2.5. GPE 2.5 simplifies app development by eliminating the need for manual tasks like copying Cloud JDBC drivers, setting classpaths, typing in JDBC URLs or filling in JVM arguments for connecting to local/remote database instances.

GPE 2.5 provides support for:

  • Configuring Cloud SQL/MySQL instances
  • Auto-completion for JDBC URLs
  • Creating database connections in Eclipse database development perspective
  • OAuth 2.0 for authentication.

Configuring Cloud SQL/MySQL instances
App Engine provides a local development environment in which you can develop and test your application before deploying to App Engine. With GPE 2.5, you now have the ability to configure your local development server to use a local MySQL instance or a Cloud SQL instance for testing. When you choose to deploy your app, it will use the configured Cloud SQL instance for App Engine.

Auto-completion for JDBC URLs
GPE 2.5 supports auto-completion for JDBC URLs, and quick-fix suggestions for incorrect JDBC URLs.

Creating database connections in Eclipse database development perspective
The Eclipse database development perspective can be used to configure database connections, browse the schema and execute SQL statements on your database.

Using GPE 2.5, database connections are automatically configured in the Eclipse database development perspective for the Development SQL instance and the App Engine SQL instance.

You can also choose to manually create a new database connection for a Cloud SQL instance. In GPE 2.5, we have added a new connection profile for Cloud SQL.

GPE 2.5 now uses OAuth 2.0 (earlier versions were using OAuth 1.0)  to securely access Google services (including Cloud SQL) from GPE. OAuth 2.0 is the latest version of the OAuth protocol focussing on simplicity of client development.

Can’t wait to get started?
Download GPE here and write your first App Engine and Cloud SQL application using GPE by following the instructions here.

Google hope GPE 2.5 will make cloud application development using App Engine and Cloud SQL a breeze. We always love to hear your feedback and the GPE group is a great place to share your thoughts.
