Where next after the Google Earth API?

December 2, 2015

With the end of the Google Earth API imminent we are having a look at what various sites that depend, or used to depend on the Google Earth API are doing about it. Earlier this year we did a showcase of sites that use the Google Earth API and we will have a look at a selection of those sites.

The first is Rally Navigator. It is a comprehensive online application for creating rally road books, which are a set of instructions used by rally drivers and their co-pilots to map out a course and know what is coming next at each turn of the road. Knowing that the Google Earth API was coming to an end, the developers of Rally Navigator redesigned it to use Google Maps instead. Although it now lacks 3D effects we do not believe it has lost any essential features as a result of the conversion and has gained more features with time. So if you are a rally driver (or co-pilot) then you should definitely check it out. It has both free and paid for versions.

Next up is GETeach. This site was converted to use Google Maps even before we reviewed it earlier this year, but they left the Google Earth version online and it can still be found here. GETeach is designed to use as much screen space as possible for the maps, which leaves very little space for menus or other information telling you what it does. So the first thing you should do is view the help page to get an idea of its features and how to access them.

We do feel that the loss of the Google Earth API in this case does mean the loss of a lot of useful features that simply cannot be replaced by Google Maps, notably the loss of historical imagery and 3D imagery. Although Google Maps does have 3D imagery, it is not accessible via the Google Maps API as is used for this site. Even with the loss of the Google Earth API, however, it is still a great site and would be very useful in the classroom, so be sure to check it out.

Next is Flightradar24, a flight tracking website that shows the live locations of flights around the globe. It used to have a 3D view, which used the Google Earth plugin to show a model of an aircraft in the correct location on its route. They currently have a message stating that due to the demise of the Google Earth plugin, they are currently working on a replacement 3D experience. We will have to wait till they are done to see how it compares to the old Google Earth API experience.

Last but not least is GEFS Online, a popular flight simulator based on the Google Earth API. As far as we can tell, no significant development work has been done on the site for quite some time, with the last blog entry being nearly two years old. We can only guess that there are no current plans to move to an alternative platform and that the site will die along with the Google Earth API.

Google Earth plugin showcase: FlightRadar 24

February 18, 2015

This is the tenth in our series showcasing the Google earth plugin. Today we are looking at FlightRadar24, a website that shows live air traffic around the world.

FlightRadar24 uses a number of different data sources to track aircraft. One of the main sources, ADS-B, requires special equipment on board the aircraft as well as detectors on the ground. Only about 65% of commercial passenger aircraft have the necessary equipment, so do not expect to see all air traffic on the map. To learn more about how it works, see their ‘How it works’ page.

The main interface uses Google Maps. To see the Google Earth plugin in action, select an aircraft, then click the ‘3D’ button on the left hand side of the screen below the picture of the aircraft. The ‘3D’ button opens ‘Cockpit View’, which uses the Google Earth plugin to show the view from the aircraft. It includes a basic instrument panel and will also display the locations of any other aircraft in the vicinity. It can also show a model aircraft, although it is a generic gray model that does not correspond to the specific aircraft you are tracking.

Coming in to land, Vancouver, Canada.

Most of the time, aircraft will be flying too high to see much of Google Earth’s 3D imagery. Even if you pick an aircraft that is landing, you may find it is flying too fast to load all the 3D imagery before you have gone past. We also discovered that the positioning is not always accurate, as the aircraft we tracked missed the runway by over a hundred metres.

You will need to have the Google Earth plugin installed, a browser that supports it, and in most cases, you will have to allow the plugin to run on the flightradar24.com site.

Several times we experienced glitches with the graphics, we think because the view is constantly moving and the Google Earth plugin can’t keep up. Reloading the page usually fixed it, however.

The flight of Asiana #214 in Google Earth

December 30, 2013

Back in July, Asiana Airlines Flight 214 crash landed on final approach to San Francisco International Airport. While three were killed in the crash, the other 304 passengers thankfully survived. The folks at Flightradar24 have taken the data from the plane’s transponder and analyzed the final 2-1/2 minutes of data from it.

In their words:

We have analyzed the last 150 seconds of data from flight ‎#OZ214. It looks like the ADS-B transponder continued to transmit data for about 10 seconds after the first impact. You can also see that the altitude increased after the first impact, when the aircraft bounced up in the air. The ground speed in the last seconds of the flight was only 112 knots.

Updpate: Sent in by a GEB reader, you can also download this KMZ file that adds the “ideal flight path” to the file and tweaked the track so that viewers can ‘fly’ along both flight paths using the Touring feature of Google Earth.
