News roundup

BBC News’ Click Online’s series covers Google Earth in their article entitled Portal race goes local and global. It has some nice big-picture observations, but then the article’s credibility gets hammered by a whopper:

Google Earth has certainly hogged the limelight, but as we are discovering in this series, good ideas are rarely original. One day before Google Earth emerged, MSN launched Virtual Earth. It is not 3D, but the idea is pretty much the same.

Google Earth was launched June 28. MSN Virtual Earth was launched July 24/25. JFGI. When you get your basic chronology wrong, that somehow doesn’t inspire confidence in the authoritative tone of the rest of the article.

The New York Post, meanwhile, has found a Queens assemblyman (reg. req.), Michael Gianaris, who appears to have been shown Google Earth and who didn’t like what he saw. So he’s fired off a letter, cc-ing it to Homeland Security.

He grants that Google Earth “may be entertaining”, but notes:

Whenever terrorists are captured, their computers always contain photos and layouts of sensitive locations. And I don’t know what rationale could exist for providing them in any easy online format, free of charge.

Ah yes, those broke terrorists with their computers. I don’t know what rationale could exist for providing them with computers either, or the internet, for that matter. Let’s register fax machines too, Soviet style. Let’s close this Open Society, shall we, just to thwart the terrorists.

The Post ends with:

It’s not the first time that satellite photos have sparked concerns about security. The Pentagon says some areas are considered off limits to prying satellite cameras. And it has an agreement with two private firms, Digital Globe and Space Imaging, that limits the pictures they make public.

Just wait until they find out that unpatriotic foreign firms have no such agreements. I give them a week.

Another way to advertise in Google Earth: Geoglyphs

aus.gifWe’ve been making art intended for aerial viewing for thousands of years; there’s the Uffington White Horse from 1,000 BC, the Nazca lines, from 200 BC – 600 AD, and the Native Americanintaglios in the Southwestern US, for example. More recent geoglyphs also abound. The world’s largest is Marree Man, in Australia, made in 1998.

Until recently, these geoglyphs were intended for the gods or for the rare airplane overflight; now Google Earth users are discovering them in droves. Wherever the earth is a canvas for artistic expression, Google Earth is proving to be an ideal viewer.

My guess is that at this very moment there are plans afoot to take advantage of this newfound potential audience. Over the next three years, as satellite images are refreshed, I suspect we will see a boom in geoglyphs. Not just by artists, but also by advertisers, who will soon latch on to the idea that there is free advertising space to be had inside all the world’s mapping applications.

(Wikipedia definition of geoglyph. I’ve added Marree Man and the Nazca lines to my Tagzania feed.)

Brian Flood assesses Google Earth

GIS (and .NET) pro Brian Flood weighs in with assessment of Google Earth as an Enterprise GIS client.

Brian is most enthusiastic about the network link:

This one feature opens the door to an enormous amount of real time customization and will probably push GE as the de facto standard for 3D visualization over the internet.

He also points to some limitations the free client has vs. the pro version when it comes to streaming vectors from servers. Finally, he seems to have built a pretty robust KML and WMS server for Google Earth, which is promising, considering that he blogs at a company that specializes in GIS solutions for municipalities.

Google Earth needs you!

Google is hiring a tools engineer for Google Earth. Requirements:

3+ years of development experience.

Excellent Python or C++ programing skills.

Excellent Unix/Linux and shell scripting skills.

Perl and Java a plus.

Excellent communication skills.

BSCS or MSCS.

GIS experience is desirable, but not required.

That should beat the hell out of hacking the app. And shall we start a Google Earth for Linux rumor now, or later?

(US) National Weather Service does KML

It’s not the most stunning use of KML ever, but it did get a mention on Slashdot: The Tulsa forecasting office of the NWS is now offering local forecast files wth maximum and minimum temperatures in KML.

Some of the scraping efforts already undertaken by the amateurs are truly useful, but it’s good to see government agencies adopting the format and deeming Google Earth as a popular enough platform to start publishing to. (Thanks, Ron)

Brave New Earth

Google Earth is proving to be many things to many people – mapping tool, information browser, game board, learning tool for history and geography… But it is also exciting futurologists for its potential as a mirror world – a shared digital space that is virtually inhabited by users.

Jerry Paffendorf will be looking at Google Earth in just this context in his presentation “Brave New Virtual Worlds” at the World Futures Studies Federation 2005 conference in Budapest in the coming week.
