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.

|Naval Research Laboratory Leverages SGI Visualization and Storage Solutions to Advance Ocean, Atmospheric and Space Sciences
|128-Processor Silicon Graphics Prism and SGI InfiniteStorage TP9700 RAID Array Enable Scientific Breakthroughs
ORLANDO, Fla. I/ITSEC 2005, Booth 101, (Nov. 29, 2005)—Silicon Graphics (OTC: SGID) today announced that the Naval Research Laboratory (NRL) in Washington, D.C. has purchased SGI® visualization and SGI® InfiniteStorage solutions to help visualize, store and share data for critical applications, including immersive real-time visualization of satellite imagery, computational fluid dynamics, ocean and weather modeling, and space physics.
"NRL is the premier scientific research laboratory within the Department of Defense supporting scientists from various disciplines such as chemistry, computational fluid dynamics, biochemistry, space physics, and many others," said Thomas Stanley, director of defense and intelligence, SGI Federal. "The lab needed a visualization solution that was powerful enough and versatile enough to accommodate many different types of scientific applications. The Silicon Graphics Prism system is designed from the ground up to solve the most challenging visualization problems facing scientists and engineers."
A complete, advanced visualization system for Linux® and one of the largest Silicon Graphics Prism™ systems in the U.S. powered by 128 Intel® Itanium® 2 processors was specifically designed to help technical professionals like those at NRL address some of the world’s most critical problems. With the Silicon Graphics Prism, SGI has combined standards-based Intel® Itanium® 2 processors and the Linux operating environment with SGI’s world-renowned advanced graphics for unbeatable visual performance and shared-memory architecture.
One of the missions of the visualization laboratory at NRL is the development of new techniques, algorithms, and methodologies to cope with the very large datasets that are being created by the scientific community that NRL serves. In particular, the area of computational fluid dynamics and GIS image analysis research have yielded terabytes of data that researchers at NRL extract and analyze for important flow features buried within these huge datasets.
Using a Silicon Graphics Prism visualization system and SGI® InfiniteStorage technology, NRL has created a DoD-wide resource for researchers to visualize their complex data, store it and share it among multidisciplinary teams. This resource makes possible the kinds of scientific breakthroughs required to advance a broad range of scientific research, technology and advanced development directed toward maritime applications that are vital to conducting U.S. Navy and Marine Corps operations in the 21st century.
"We have a host of real-world scientific visualization problems that are benefiting from this visualization-storage solution from SGI," said Dr. Hank Dardy, chief scientist for advanced computing at NRL’s Center for Computational Science. "Built on the SGI NUMAflex shared-memory architecture, our Silicon Graphics Prism visualization system has the large, complex data memory functionality we needed for our real-time technical environments. In addition, with an SGI storage area network coupled with the CXFS shared filesystem, we can read and write data directly over the SAN to and from disk, eliminating duplication and bottlenecks for our data-intensive applications."
Earlier this year NRL purchased a 128-processor Silicon Graphics Prism visualization system, powered by Intel Itanium 2 processors and running the Linux® operating environment. To store huge volumes of data, the lab installed 56TB of SGI® InfiniteStorage TP9700 Fibre Channel RAID array, the industry’s first Fibre Channel storage array equipped with 4Gb per second interfaces, whose disk space is shared as an SGI InfiniteStorage CXFS™ clustered filesystem. By eliminating network data overhead, latencies and copies, CXFS enables the typical data-intensive workflow to complete 20 to 80% faster, while reducing the administration overhead, speeding backups and reducing disk needed.
Government research laboratories like NRL are also increasingly turning to InfiniBand interconnect solutions to dramatically improve performance, efficiency, scalability and overall network reliability. SGI recently reconfigured the TP9700 at NRL to utilize new native InfiniBand host connectivity.
SGI InfiniteStorage disk arrays are built on Engenio technology that are specifically designed to meet the demanding needs of high-performance computing environments such as NRL that require InfiniBand, the leading standard for HPC server interconnects. InfiniBand is the only 10Gb per second transport that enables industry standard servers to be clustered together for reliable, available, scaleable and high performance enterprise computing. The InfiniBand solution for the SGI® Altix® family of servers addresses typical bottlenecks and provides technical customers with a world-class clustering solution for their most demanding application workloads.

|Softcore Stuff (software & data bits)…
||from Space Imaging
|The SRTM data sets result from a collaborative effort by the National Aeronautics and Space Administration (NASA) and the National Imagery and Mapping Agency (NIMA), as well as the participation of the German and Italian space agencies, to generate a near-global digital elevation model (DEM) of the Earth using radar interferometry. The SRTM instrument consisted of the Spaceborne Imaging Radar-C (SIR-C) hardware set modified with a Space Station-derived mast and additional antennae to form an interferometer with a 60 meter long baseline. A description of the SRTM mission, can be found in Farr and Kobrick (2000).
The SRTM-1 and SRTM-3 are preliminary terrain height data sets. NASA has taken significant efforts to avoid confusion of the SRTM-1 and SRTM-3 digital elevation models with the NIMA standard (Digital Terrain Elevation Data) DTED-1 and DTED-2 terrain height data sets. The SRTM-1 and SRTM-3 data products result from special processing of the SRTM data in response to requests from Principal Investigators selected under NASA’s Solid Earth and Natural Hazards Program, as well as other special requests from NIMA and NASA. The SRTM-1 and SRTM-3 data are preliminary products distributed for evaluation by the research and applications user community.
Synthetic aperture radars are side-looking instruments and acquire data along continuous swaths. The SRTM swaths extended from about 30 degrees off-nadir to about 58 degrees off-nadir from an altitude of 233 km, and thus were about 225 km wide. During the data flight the instrument was operated at all times the orbiter was over land and about 1000 individual swaths were acquired over the ten days of mapping operations. Length of the acquired swaths range from a few hundred to several thousand km. Each individual data acquisition is referred to as a "data take."
SRTM was the primary (and pretty much only) payload on the STS-99 mission of the Space Shuttle Endeavour, which launched February 11, 2000 and flew for 11 days. Following several hours for instrument deployment, activation and checkout, systematic interferometric data were collected for 222.4 consecutive hours. The instrument operated virtually flawlessly and imaged 99.96% of the targeted landmass at least one time, 94.59% at least twice and about 50% at least three or more times. The goal was to image each terrain segment at least twice from different angles (on ascending, or north-going, and descending orbit passes) to fill in areas shadowed from the radar beam by terrain.
This ‘targeted landmass’ consisted of all land between 56 degrees south and 60 degrees north latitude, which comprises almost exactly 80% of the total landmass.

|Proposed Coking Coal Mine in Central Kalimantan
|VizMAP Pty Ltd was contracted by PT Asmin Koalindo Tuhup (AKT) to create a computer based visualisation of the complete mining facilities as planned to be when mining of the rich coking coal reserve in central Borneo is fully underway.
VizMAP used the TerraTools software from TerraSim Inc. (Pittsburgh, PA USA) to create the “virtual” 3D database. Supplemental 3D models of excavators, trucks, conveyors, bulldozers, barges and tugs, etc. were subcontracted. Landsat imagery provided the broad scale ground texture, whilst the SRTM (NASA Shuttle Radar Topographic Mission) data provided the bulk of the digital terrain modelling. Finer modelling, particularly of the actual mine site, was sourced directly from the mining plan and supplied in DXF.

|Microsoft to start testing new Messenger
|Microsoft is expected to begin testing soon of Windows Live Messenger, an update that expands the consumer instant messaging software into areas such as Internet phone calling.
The revamp is essentially an expansion of MSN Messenger. It adds a number of features and continues the program’s migration from a place to share short text messages into a manager for any number of modes of communication.
Various enthusiast sites, including Mess.be and BetaNews, reported that a private beta of Live Messenger is imminent, while another fan site, Messenger Blog, offered purported screenshots of the new software. Microsoft declined to comment on Monday, but had promised a beta version would come this month.
Microsoft showed a preview of the instant messaging program at its Live services kickoff early last month.
At the time, Microsoft demonstrated folder-sharing and voice over Internet Protocol (VoIP) features. The company later clarified that the feature that enables people to call a traditional phone would be a paid service provided by a partner. Microsoft is expected to partner with MCI, according to sources familiar with the companies’ plans, though the partnership may not be exclusive.
As for folder sharing, Microsoft showed the ability for two buddies to have a permanent shared folder. Either person could update the documents inside, and these are then synchronised with one another. The company also demonstrated evolutions of Live Messenger that would allow it to act as a means of managing contact information and as a hub for social networking.
Plans for the Messenger beta were earlier reported by Microsoft Watch.

|Whazzup Next – with 20/20 Foresight…
|A Parting Gesture…
|To the citizens of the United States of America…
|In light of your failure to elect a competent President of the USA and thus to govern yourselves, we hereby give notice of the revocation of your independence, effective immediately.
Her Sovereign Majesty Queen Elizabeth II will resume monarchical duties over all states, commonwealths, and territories (excepting Kansas, which she does not fancy).
Your new prime minister, Tony Blair, will appoint a governor for America without the need for further elections.
Congress and the Senate will be disbanded.
A questionnaire may be circulated next year to determine whether any of you noticed.
To aid in the transition to a British Crown Dependency, the following rules are introduced with immediate effect:
- You should look up "revocation" in the Oxford English Dictionary. Then look up aluminium, and check the pronunciation guide. You will be amazed at just how wrongly you have been pronouncing it.
- The letter ‘U’ will be reinstated in words such as ‘favour’ and ‘neighbour.’ Likewise, you will learn to spell ‘doughnut’ without skipping half the letters, and the suffix -ize will be replaced by the suffix -ise. Generally, you will be expected to raise your vocabulary to acceptable levels. (look up ‘vocabulary’).
- Using the same twenty-seven words interspersed with filler noises such as "like" and "you know" is an unacceptable and inefficient form of communication. There is no such thing as US English. We will let Microsoft know on your behalf. The Microsoft spell- checker will be adjusted to take account of the reinstated letter ‘u’ and the elimination of -ize. You will relearn your original national anthem, God Save The Queen.
- July 4th will no longer be celebrated as a holiday.
- You will learn to resolve personal issues without using guns, lawyers, or therapists. The fact that you need so many lawyers and therapists shows that you’re not adult enough to be independent. Guns should only be handled by adults. If you’re not adult enough to sort things out without suing someone or speaking to a therapist then you’re not grown up enough to handle a gun.
- Therefore, you will no longer be allowed to own or carry anything more dangerous than a vegetable peeler. A permit will be required if you wish to carry a vegetable peeler in public.
- All American cars are hereby banned. They are crap and this is for your own good. When we show you German cars, you will understand what we mean.
- All intersections will be replaced with roundabouts, and you will start driving on the left with immediate effect. At the same time, you will go metric with immediate effect and without the benefit of conversion tables. Both roundabouts and metrication will help you understand the British sense of humour.
- The Former USA will adopt UK prices on petrol (which you have been calling gasoline)-roughly $6/US gallon. Get used to it.
- You will learn to make real chips. Those things you call French fries are not real chips, and those things you insist on calling potato chips are properly called crisps. Real chips are thick cut, fried in animal fat, and dressed not with catsup but with vinegar.
- The cold tasteless stuff you insist on calling beer is not actually beer at all. Henceforth, only proper British Bitter will be referred to as beer, and European brews of known and accepted provenance will be referred to as Lager. American brands will be referred to as Near-Frozen Gnat’s Urine, so that all can be sold without risk of further confusion.
- Hollywood will be required occasionally to cast English actors as good guys. Hollywood will also be required to cast English actors to play English characters. Watching Andie Macdowell attempt English dialogue in Four Weddings and a Funeral was an experience akin to having one’s ears removed with a cheese grater.
- You will cease playing American football. There is only one kind of proper football; you call it soccer. Those of you brave enough will, in time, be allowed to play rugby (which has some similarities to American football, but does not involve stopping for a rest every twenty seconds or wearing full kevlar body armour like a bunch of nancies).
- Further, you will stop playing baseball. It is not reasonable to host an event called the World Series for a game which is not played outside of America. Since only 2.1% of you are aware that there is a world beyond your borders, your error is understandable.
- You must tell us who killed JFK. It’s been driving us mad.
- An internal revenue agent (i.e. tax collector) from Her Majesty’s Government will be with you shortly to ensure the acquisition of all monies due (backdated to 1776).
- Daily Tea Time begins promptly at 4 pm with proper cups, never mugs, with high quality biscuits (cookies) and cakes; strawberries in season.
