For the first time, VirtualGeography is going to be sent out on a dedicated List Server so I hope everything goes to plan. To do this, we’re using our sister site Grime. The Grime site was born way back in 1999 (12 months before VizMAP) as a vehicle to point to useful GIS freeware. We run it on a shoestring but it still gets an extraordinary amount of traffic. To go directly to the Grime freeware pages, start here.

The Grime List Server for VirtualGeography has been configured for newsletters only (i.e. from me to you) so you can’t respond to this e-mail. If you want to subscribe or unsubscribe, just do it (for the time being) as per the links at the bottom. If you want to respond, send me an e-mail here.

VizMAP is in the middle of a few very interesting projects at the moment, not the least impacting being a visualisation of a local port. This should be done and dusted by the next issue so look out for some pretty pictures then. In fact there is so much stuff coming up that we mightn’t get a chance to scratch for many months.

If you didn’t already know, VirtualGeography is a collection of interesting snippets from all over the shop, dealing with industry issues concerning the computer based visualisation of geography and a few other associated (or otherwise) interesting bits and pieces. You are receiving this either because you subscribed to VirtualGeography or you have had recent dealings with VizMAP Pty Ltd. If you do not wish to receive further instalments of VirtualGeography, just click on the unsubscribe link at the bottom of this e-mail. 

A new VirtualGeography is pushed out every now and then when we’ve collated enough interesting bits and pieces, which shouldn’t be too big a drain on your mailbox if you’re not already subscribed (of course it won’t be a drain on your mailbox if you ARE subscribed, either ). The regularity of the distribution may vary depending on what else is going on at VizMAP at the time. If you know of anyone who might like to get VirtualGeography, feel free to forward this to them and ask them to subscribe. By the way, subscription and unsubscription details are at the bottom (click here).

So, g’day to all you enthusiasts requiring to visualise and simulate both urban and rural geographic information (GIS), cartography, photogrammetry, remote sensing, digital elevation modelling (DEM) and general mapping.

By the spelling of "Visualisation" you may have already guessed that we’re not US based – that’s a good thing, or at least not a bad thing. This comes to you from Mooloolaba on the Sunshine Coast of Queensland, Australia, where it’s beautiful one day and perfect the next. As a postscript to that, you can have a look at the Mooloolaba beach, now, 800m from where I sit as I write this, here.

The link between visualisation and mapping may seem a little esoteric if this is your first encounter with this sort of stuff, but let me tell you, the bond is significant… but enough of that: on with the show… I hope you like it. Any feedback you might have is highly appreciated. E-mail me here to make your comments. Enjoy… Graeme Brooke VizMAP Pty Ltd

…The first, relatively simple step toward a Second Earth, many observers predict, will be integrating Second Life’s avatars, controls, and modeling tools into the Google Earth environment. Groups of users would then be able to walk, fly, or swim across Google’s simulated landscapes and explore intricate 3-D representations of the world’s most famous buildings. Google itself may or may not be considering such a project. "It’s interesting, and I think there are people who want to do that," says John Hanke, director of the division of the company responsible for Google Earth. "But that’s not something where we have any announcements or immediate plans to talk about it."

A second alternative would be to expand the surface area of Second Life by millions of square kilometers and model the new territory on the real earth, using the same topographical data and surface imagery contained in Google Earth. (The existing parts of Second Life could remain, perhaps as an imaginary archipelago somewhere in the Pacific.) That’s a much more difficult proposition, for practical, technical reasons that I’ll get to later. And in any case, Linden Lab says it’s not interested.

But within 10 to 20 years–roughly the same time it took for the Web to become what it is now–something much bigger than either of these alternatives may emerge: a true Metaverse. In Neal Stephenson’s 1992 novel Snow Crash, a classic of the dystopian "cyberpunk" genre, the Metaverse was a planet-size virtual city that could hold up to 120 million avatars, each representing someone in search of entertainment, trade, or social contact. The Metaverse that’s really on the way, some experts believe, will resemble Stephenson’s vision, but with many alterations. It will look like the real earth, and it will support even more users than the Snow Crash cyberworld, functioning as the agora, labo­ratory, and gateway for almost every type of information-based pursuit. It will be accessible both in its immersive, virtual-reality form and through peepholes like the screen of your cell phone as you make your way through the real world. And like the Web today, it will become "the standard way in which we think of life online," to quote from the Metaverse Roadmap, a forecast published this spring by an informal group of entrepreneurs, media producers, academics, and analysts (Cascio among them)…

The prototype Tangible 3D system combines a 3D display with a "haptic glove". The display creates lifelike images appear in just in front of a flat screen. It creates the illusion of depth by showing slightly different images to each of the viewer’s eyes. This means no special glasses are needed.

Attached to the display is a haptic glove. Once inside, a user’s hand is touched by numerous force-feedback components to make it feel as if it interacting with something solid.

The system can also translate real-world objects into virtual representations. Two cameras image the items in 3D so that they can be displayed on the screen. A connected computer then processes the 3D image to generate a tactile representation of the object.

This set up means that if the object being filmed is moved, the three-dimensional image also moves in real-time and the user will feel the movement with their hand.

That certainly was the case for Suzanne Seggerman, co-founder and president of Games for Change, the social change/social issues branch of the Washington, D.C.-based Serious Games Initiative. While working as a documentary film producer for PBS, a co-worker slipped Seggerman a diskette containing Jim Gasperini’s government simulation game, Hidden Agenda. “I had played a little Asteroids while in college,” the New Yorker remembers, “but I definitely wasn’t a gamer.”

That all changed after she spent a weekend with her computerized present. “It was a transformative experience for me,” Seggerman says. “I sat up in the attic while a party was going on below—and I’m never one to miss a good party—and must have played the game for 10 hours straight.”

“I learned more about politics by playing Hidden Agenda than by reading 10 newspapers,” she adds.

Seggerman continued making films for a few years, but that ‘aha’ moment was never far from her thoughts. “I made a mental note that it had been something important and powerful and that I’d get back to that place at some point in my career,” she says.

Friends,Earthlings, ETs—lend me your sensory organs!

I send you greetings and good wishes at the beginning of another year. I’ll be celebrating (?) my 90th birthday in December—a few weeks after the Space Age completes its first half century.

When the late and unlamented Soviet Union launched Sputnik 1 on 4 October 1957, it took only about five minutes for the world to realise what had happened. And although I had been writing and speaking about space travel for years, the moment is still frozen in my own memory: I was in Barcelona attending the 8th International Astronautical Congress. We had retired to our hotel rooms after a busy day of presentations when the news broke—I was awakened by reporters seeking comments on the Soviet feat. Our theories and speculations had suddenly become reality!

Notwithstanding the remarkable accomplishments during the past 50 years, I believe that the Golden Age of space travel is still ahead of us. Before the current decade is out, fee-paying passengers will be experiencing sub-orbital flights aboard privately funded passenger vehicles, built by a new generation of engineer-entrepreneurs with an unstoppable passion for space (I’m hoping I could still make such a journey myself). And over the next 50 years, thousands of people will gain access to the orbital realm—and then, to the Moon and beyond.

During 2006, I followed with interest the emergence of this new breed of ‘Citizen Astronauts’ and private space enterprise. I am very encouraged by the wide-spread acceptance of the Space Elevator, which can make space transport cheap and affordable to ordinary people. This daring engineering concept, which I popularised in The Fountains of Paradise (1978), is now taken very seriously, with space agencies and entrepreneurs investing money and effort in developing prototypes. A dozen of these parties competed for the NASA-sponsored, US$ 150,000 X Prize Cup which took place in October 2006 at the Las Cruces International Airport, New Mexico.

The Arthur Clarke Foundation continues to recognise and cheer-lead men and women who blaze new trails to space. A few days before the X Prize Cup competition, my old friend Walter Cronkite received the Foundation’s Lifetime Achievement Award. I have known Walter for over half a century, and my commentary with him during the heady days of the Apollo Moon landings now belongs to another era. A space ‘pathfinder’ of the Twenty First Century, Bob Bigelow, was presented the Arthur C. Clarke Innovator Award for his work in the development of space habitats. With the successful launch of Bigelow Aerospace’s Genesis 1, Bob is leading the way for private individuals willing to advance space exploration with minimum reliance on government programmes.
