Damocles, take 2

Remember the Damocles Arctic sea ice project I blogged last week? The page associated with the Google Earth network link (KMZ) is now looking a whole lot more informative — explaining precisely what all the data types portrayed are.

While you’re playing with the network link, be sure to turn on the AMSR-E total ice concentration layer for a very colorful and informative take on the effect of the Gulf Stream on the sea ice. All this is of course screaming out for time lapse motion. (Thanks to Pierre-Philippe Mathieu at ESA for the original heads up. Is ESA’s EOMD planning anything with Google Earth, BTW? Can’t let NASA have all the fun:-)

The Oz Report, now via Google Earth

loopdeloop.pngThe Oz Report, a website fanatically dedicated to all things hang gliding and paragliding, has been implementing Google Earth functionality in some very interesting ways.

First, the site maintains an exhaustive library of global hang gliding sites, viewable both in Maps and as a network link (KMZ). Most locations have a link to information about the site.

Second, the Sportavia International Open hang gliding competition is currently underway in Australia, and each day, The Oz Report adds the flight paths of competitors to this network link (KMZ). While we’ve seen Google Earth used for something similar before (the XAlps), the paths drawn by The Oz Report in Google Earth are a big improvement in terms of visualization, and very pretty to boot. (You can even fly along the paths of individual hang gliders. Instructions are here.)

RoboGEO gets an update

RoboGEO really has quite a few tricks up its sleeve when it comes to georeferencing photographs. It aready provides Flickr users with Flickr2Map, a free service that links geotagged Flickr images to their location in Google Earth, Maps, and other apps.

RoboGEO also makes a standalone PC application that lets you marry GPS data with pictures in many different ways — version 3.1, out today, intergrates with Flickr and can handle Google Maps’ new API. (It already does KML, obviously.)

New improved GPS Visualizer

GPS Visualizer, the web app that lets you convert GPS data files to Google Earth KML while adding lots of customization, just got better. Writes Adam Schneider:

GPS Visualizer can now draw Google Earth tracks that are colorized by altitude, speed, etc. Unfortunately, GE only lets you assign one color to each placemark, so I have to do it by breaking the track into hundreds of individual placemarks collected in a folder — but it’s actually not too bad. (In Google Maps, doing the same thing is terrible.)

That should produce some stunning results for anyone who hang glides, hikes, or drives. You can even colorize according to your heart rate (!).

Google Earth Locals

While Google Earth has search built in for businesses and layers for restaurants, bars and museums, these features only work in a few countries. For most of the world, this kind of local cultural knowledge has been provided ad hoc by committed amateurs, but now some enterprising businesses are taking advantage of this gap in the market.

Exhibit A: Ticnet.se, a Swedish service I use regularly to buy tickets to concerts, has come out with a network link that lists all venues in Sweden, and also all its upcoming events sorted by dated folders, with pop-ups for information. It’s still beta — the obvious thing missing is the link to the ticket-sale page in the pop-up — but it is immediately useful for things beyond tickets: It comes with high resolution overlays for Sweden’s second city, G√∂teborg, which has not yet been blessed with Google Earth’s own hi-res images.

(The dated folders are a kind of stop-gap measure for doing your own time-based search. If/when Google Earth adds a time browser, this kind of network link will become even easier to use.)

Exhibit B: About month ago Cape Town Magazine came out with a static KML file that obsessively listed every hip coffee shop, restaurant and clothing store in Cape Town, and much else besides. Most items are linked back to articles in the magazine, providing a whole new way of navigating its content.

At the moment, you have to send them an email to get access to the file, but they are planning to soon come out with a proper network link, so that updated content in their magazine is reflected simultaneously on Google Earth. That’s a clever tactic — not just because it increases interest for new content, but because I think there is a first-mover advantage in effect here: Whoever lays claim to a city with comprehensive coverage first will likely become the default option with the locals — there is no point in having four placemarks enabled for each museum.

More short news

Bull of Bull’s Rambles blogs how he’s managed to convert simple KML files into NASA World Wind add-on files, and posts some examples. He doesn’t post the application he used, though. If he were to do so, World Wind would suddenly have a wealth of data available. But why not support KML (and network links) natively?

Google Earth Tidbits

So much news, so little time. Here we go…

Sell your KML scripting skills to the entertainment industry: “A major film studio” wants to use Google Earth to promote a movie, and they need your help.

Digitally Distributed Environments decides to use several of Microsoft’s “bird’s eye views” in Live Local to generate a real 3D map of a location. The result is a-m-a-z-i-n-g (check out the QT movie). If I am not mistaken, this is akin to the SilverEye technology that Geotango possesses and which Microsoft bought that company for.

How often is Google Earth mentioned on the internets? This much.

A blog to watch if you do GPS: Jeepx.

CNET asks, Where on Google Earth is this? Brand watchers among us, note how CNET did not ask “Where on MSN Live Local…”, “Where on World Wind…” (despite the lovely alliteration) or “Where on ESRI ArcGIS Explorer…”.

Talking of the competition: Matt Giger, maker of EarthBrowser, has just started blogging. So has Chris Maxwell, a lead developer of World Wind. And Bull’s Rambles, a new blog dedicated to “this and that, mainly World Wind rants” lives up to the promise of its tag line, offering up three reasons why the free version of Google Earth isn’t really free. (Can we really not take screenshots? :-)
