Google Earth performance update

In case you were wondering if the popularity of Google Earth is straining Google’s servers (and some have wondered), you can rest assured:

In a support forum post, PenguinOpus of the Google Earth team mentions:

Google Earth servers currently have enough capacity that no rate-limiting has occurred in several months. Your performance will be controlled by your own ISP’s throughput and your latency to our servers. Ping kh.google.com. <100msec, good. >200msec, not-so-good.

(Here in Sweden my average ping response is 22.6msec (!))

Today’s tidbits

Chris Davis of 9Rules posts a beginner’s tutorial for writing simple KML placemarks, and promises more are to come.

Fotocade’s Archi-maps contains KML files for several places in the UK highlighting interesting architectural landmarks. Many of the placemarks are annotated by photos by Andy Marshall, an architectural photographer. If you like them, you can buy them. It’s an interesting new way to sell stock photography — by georeferenced location.

Safe Software, the 363-kg gorilla of GIS transformation tools, has announced FME2006, their latest version. It does KML (of course).

Not to be outdone, Brian Flood is putting the finishing touches on Arc2Earth before its official 1.0 release. Arc2Earth turns output made by pros with ESRI ArcGIS into KML, so that the rest of us can consume it with Google Earth.

Earth (no) Contest

Earth Contest issues a press release claiming “over 60,000 new users” since its “initial launch” two weeks ago. That confuses me. Are we talking about the old game, which was actually launched in October, and then relaunched on December 17? Or are we talking about the “big game”, which was announced then and scheduled to launch at “midnight January 2006” but which isn’t actually running yet? All you can do is pre-register and hang out in a deserted players lounge forum (275 registered members), where posts by different authors sound the same. The game is free and promises “big prizes”. What could the business model possibly be? Had to go read the small print… Ah, yes:

Social spying

A Spanish-language article in the Miami-based El Nuevo Herald, translated into English by Robert at 26th Parallel, identifies yet another collaborative trend made possible by Google Earth: Social spying.

El Nuevo Herald reports on a burgeoning new pastime among some Cuban expats in the US: Finding what they purport to be sensitive or secret information about Castro’s regime in Cuba and then marking these up in Google Earth via the Google Earth Community site.

What’s most interesting here, I think, is not so much the accuracy (or lack thereof) of the sites that are marked and labeled. Rather, it is that the trend exists at all and that it gets a write-up in a local paper.

The ability for anyone to freely publish placemarks to the Google Earth Community, and thus to Google Earth proper via the built-in Google Earth Community layers (both ranked and unranked), will lead to some interesting situations in the long term, I think. There already are the odd naming skirmishes conducted via the multiple placing of placemarks on contested areas (qv. the Falklands). But there could also be political implications if some governments, unschooled in the ways of free speech, decide that Google needs to police what is published on its servers, or face financial consequences.

I guess I was thinking of China:-) Microsoft has already decided to comply with local laws that severely limit free speech. Such conflicts of interest are bound to get more frequent. What happens if somebody starts correctly labelling China’s missile silos in Google Earth?

Sketchup for Mac plug-in (plus eye candy)

SketchUp is a 3D authoring tool for both Mac and Windows. A few months ago, a plug-in was released that made it easy for Windows versions of the application to export objects to Google Earth. Now the Mac version is out too.

acro.jpgWhile the plug-in is only useful to SketchUp users, all Google Earth users can display the exported files. Some of the more impressive examples are available for download at the bottom of the plug-in page. (My favorite: the Acropolis [KML])

Google Earth, environmentalist tool

The San Francisco Chronicle has an article online on how Google Earth is changing the way environmentalists work. The thesis:

For environmentalists, Google Earth has turned out to be much more than another gee-whiz software development. Instead, it’s starting to look like a killer app that could change the power balance between grassroots environmentalists and their adversaries. […]

The environmental importance of this tool has not been lost on Google. “The power of Google Earth is that it’s not a map. It’s actually a real model of the real Earth,” says Rebecca Moore, a software developer who works on Google Earth. “Suddenly ordinary grassroots environmentalists have a tool that up until now only government agencies or commercial interests had. It’s leveling the playing field.”

The article mentions Moore’s own environmental work, viewable here, Sprol.com, which uses Google Earth to illustrate environmental issues, and the Sierra Club’s ANWR overlays.
