Hitwise web analyst Bill Tancer has posted a league table for portals and how their respective properties rank. In search, for example, Google is first with 47.4% of all visits, followed by Yahoo! (16.0%) and MSN (11.5%).

Hitwise also has a “Travel – Maps” category, where Bill lists the following sites, ranked by visits as a percentage of the total segment:

1. Mapquest (56.3%)
2. Yahoo! Maps (20.5%)
3. Google Maps (7.5%)
4. MSN Virtual Earth (4.3%)
5. Google Earth (2.0%)

So, Google Earth users are like the Mac users of maps:-) Actually, I’m wondering how Hitwise measures that metric for Google Earth. Unless Google provides Hitwise with logon data, I don’t see how they can tell accurately how many people use Google Earth. Or does it mean that at any one time, 2% of map and travel site visitors are downloading the standalone Google Earth application from http://earth.google.com? That’d be quite a feat — the site doesn’t serve for much else. (I’m trying to find out.)

Is Google Earth’s imagery update schedule not frequent enough for you? Aerials Express now promises to deliver its most recent US city imagery directly as a dynamic network link in Google Earth. It’s beta, and it will be offered as premium content (=pay) but there is a free demo of six regions.

I can imagine that plenty of real estate agents would be willing to pony up for such content. The only problem: When I use the demo I get overlays that simultaneously seem unrelated to the area I’m looking at and of much lower resolution than what Google Earth already has. Sure it’s beta and all, but if you write a press release, that’s your one big chance to impress. Does it work for anyone else?

[Update 21:08 UTC: Frank Taylor emails to say it’s a Mac issue. Fair enough, as I’m on a Mac:-) But the moral of the story needs to be: If you’re a company developing for Google Earth, get yourself a Mac Mini for testing, or else tell us it hasn’t been tested on the Mac. Google Earth is a consumer GIS product.]

Here’s a quick catch-up post of interesting content related to Google Earth from the past few days. Regularly scheduled posting resumes Monday morning…

• The Times of India, to their credit, reports “Google satellite images no threat, says IAF chief“. Indian Air Force Chief Marshal S. P. Tyagi is a voice of reason. (Thanks to everyone who emailed me this:-)
• I’ve been following this thread on Google Earth Community with interest over the past week: “Reverse-engineering the Adidas Game“. (Don’t forget that some very nifty solutions to the one-way interaction problem were found back in August 2005 by Mickey when he first made the GEWar game.)
• Fantastic! A GeoRSS aggregator with search by area: Mapufacture, by Mikel Maron.
• Suw Charman writes up a talk by Mikel Maron about GeoRSS at Xtech 2006. Turns out there are more GeoRSS aggregators in the pipeline: Placedb, The GeoThingy, and FoF Redux.
• European hotel booking site Booking.com integrates Google Earth into its search results. Intuitive and seamless. (Via Roell.net)
• Import KML into open source 3D authoring tool Blender with this Python script. (Via BlenderNartion)
• Use Google Earth and SketchUp to present your architectural project, win a prize, as a Stanford team did with the Green Dorm.
• Microsoft makes its updated Virtual Earth imagery available as a plugin for NASA World Wind, reports Bull’s Rambles. The plugin includes a business finder, and hence a revenue opportunty, which explains why they would be willing to bear the bandwidth costs.

Keyhole co-founder and Second Life veteran Avi Bar-Zeev writes a long post that argues Google Earth has a long way to go before it approaches what we commonly imagine to be the metaverse. It’s all about making 3D content semantic, he says, and this means that:

What we really need is a new language of object representation that encapsulates and preserves form and function, aesthetics, style, meaning, and behavior, all tightly coupled and never discarded in the “art pipeline” until the object is finally rendered on your screen.

Needless to say, he alludes to working on something like it. Avi’s post is a great read, full of lucid ideas.

[I’m not really doing his post justice. My post on the differences between Second Life and Google Earth will have to wait until I’m back in Stockholm on Sunday.]

Here’s a quick update. I’ll be travelling the next few days, so posting may be intermittent. (In the meantime, I’ve updated the Ogle Earth link list.)

• SketchUpModels.com is a very nicely designed commercial repository of models, for sale at affordable prices. There’s also a gallery of very good free content. SketchUpModels uses the iTunes model of selling intellectual property, whereas the previously blogged Form Fonts uses an subscription model, a la Rhapsody.
• Mini meme: Not one, but two scouting blogs embrace SketchUp as a tool for developing camping furniture.
• Via The Stoa Consortium, Building a New Rome: The Imperial Colony of Pisidian Antioch, a website about the ancient city of Antioch accompanying an exhibition at the Kelsey Museum of Archeology in Michigan. There is an overlay for Google Earth, but as the site also contains 2D images of 3D flythroughs of Antioch, it would be even cooler to get that 3D file into Google Earth and let us do it ourselves.

Via Bull’s Rambles comes word of NASA’s press release for World Wind 1.3.5, aimed at drumming up some publicity. It contains some excellent actual news down in the fifth paragraph:

A version written in the Java computer language that will run on Macintosh and Linux computers is scheduled for release in September 2006, [program manager for World Wind at NASA Ames Patrick] Hogan noted.

That’s wonderful to hear, given that the porting project appeared to be dormant.

Two down, two to go: Will ESRI’s ArcGIS Explorer and Microsoft’s mooted 3D virtual globe run on Macs? I doubt ESRI will embrace the Mac. (As James Fee notes, it’s a .Net application, and porting it to anything else would likely be seen as a waste of resources by its core user community), but I think Microsoft doesn’t really have a choice if it wants to make its virtual globe a social, economically viable space. Not making a Mac version would be as silly as building a Windows-only online store. (Note that Second Life and World of Warcraft both have a Mac client.)

Followers of Apple news are used to hearing about the collaboration between Maine state schools and Apple Computer. Now Google is joining the fun, donating SketchUp Pro and Google Earth for pre-installation on the 36,000 Apple laptops that students will receive in the fall, as well to teachers. Here is the announcement on the official Google blog.

The best news: “Government agencies that would like to follow Maine’s lead are welcome to drop us a line at education@sketchup.com.”

Note: Those laptops will almost certainly be the MacBooks announced yesterday, rather than the discontinued iBooks mentioned in the RFP. And it’s not clear from the announcement whether it’s Google Earth or Google Earth Plus/Pro that is being installed — perhaps because the Mac version isn’t out yet.

[Update 8:50 UTC: One more thought: Feature-wise, there isn’t much that a schoolkid could benefit from in SketchUp Pro that is missing in SketchUp free (other than that it doesn’t exist yet for the Mac). The main reason I can think of for donating SketchUp Pro is the EULA of the free version, which might restrict use on school-owned laptops. In any case, AEC and CAD professionals should expect an onlsaught of designers from Maine in a decade or so:-)]
