  • 3D Terrestrial Laser Scanning

    In November KCI purchased a RIEGL VZ-400 3D Terrestrial Laser Scanner. This portable surveying instrument can collect millions of data points within a 400 meter range in a matter of minutes. The scanner emits a light pulse outward towards a target surface and measures how long it takes for the beam to hit and return while spinning in a 360 degree pattern. The system calculates the beams horizontal and vertical angles and captures anywhere from 5 million to 45 million data points into a database called a point cloud. From each scan position a digital camera captures images which are used to color the scan points. The point cloud is then recorded into a 3D visualization program, and matched with the digital images to create a panoramic view. By taking multiple scans and using target traver...

    Shafer Kline & Warren’s Light Detection and Ranging (LiDAR) scanning provides comprehensive, high-definition survey information with unsurpassed accuracy and efficiency. SKW’s LiDAR gurus Scott Confer and Patrick Crawford provide insight into LiDAR scanning, and how they leverage the technology to engineer solutions for energy and infrastructure. Many structures lack accurate as-built documentation or site data, and without this information, companies are unable to assess their current structures or perform facility modifications and updates. With scan speeds of up to one million points per second, LiDAR technology reduces the time needed to collect survey data and produce actionable data, which allows companies to complete projects sooner and meet tight deadlines. Additionally, LiDAR scan...

    This 3D VZ-Line Laser Scanner offers superior and unrivalled long range measurement performance of up to 4000 m reflectorlessly while still maintaining completely eye safe operation (Laser Class 1). RIEGL's unique V-Line technology is based on echo digitization and online waveform processing and is the key to enabling such extreme long range measurements. The VZ-4000 operates even in poor visibility and demanding multi target situations caused by dust, haze, rain, snow, etc. which are frequently found in difficult environments such as mine sites.

Please visit Richard D Hall's website RICHPLANET.NET http://www.richplanet.net/starship.php to see all his past shows, and so much more, covering all types of alternate issues that the mainstream refuses to acknowledge. Richplanet TV: http://www.richplanet.net/index.php Published on 1 Dec 2015 In 2002 Gary McKinnon was arrested for remotely accessing files on NASA and military computer systems in the United States. Sitting in his bedroom in the UK using nothing more than a humble Windows PC with a 56K modem [sceeech Bulang Bulang Bulang sceech] he viewed the files of the worlds most powerful military organisations. Notice I have not used the word hacking, because in my opinion McKinnon did not need to do any hacking to gain access to these files. The files were publicly available for all to access on unprotected internet facing Windows PCs, without any security. This however did not stop the USA from requesting his extradition and putting him through hell for over a decade. But what was the real reason for this whole affair? Were the public being psychologically warmed to a new type of terror threat? Oh and yes there is a secret space programme. High-profile hacker Gary McKinnon claims to have some interesting information about the US Navy’s intergalactic operation – there is a top-secret fleet of “eight to ten” war ships in space, with around 25 “Non-terrestrial officers” on their books. Gary McKinnon is a British lifelong ufologist and computer expert, whose 2002 arrest for hacking into the US Navy and NASA systems was described as the ‘biggest military computer hack of all time.’ McKinnon claimed NASA’s security was so lax back then, he didn’t expect to get caught. He used a program called Landsearch to scan documents and files to look for UFO cover-ups, and he did so undetected for two years before he got caught. President Bush wanted him behind bars. McKinnon faced an intense ten year legal battle in the UK, only narrowly avoiding extradition to the USA. He has spoken before about exactly what he discovered during his time scanning NASA’s documents and files, but never in as much detail as in this interview with RichPlanet TV. McKinnon claims: In Building 8 at Johnson Space Center, Houston, there is someone whose full time job is to airbrush UFOs from images, since they are so commonly captured. He found a US Navy spreadsheet entitled ‘Non-terrestrial officers’. McKinnon admits these words “can be interpreted in various ways,” but one thing is for sure: given the name, we know they’re not based on Earth. McKinnon says there were maybe 25 rows on the excel spreadsheet with officers’ ranks and names, and that the ships had the prefix ‘USS’ just like American sea vessels. He claims there is evidence of “material transfer between ships”, of which he says there are “possibly eight to ten.” McKinnon believes all of this evidence suggests that the US has a fleet of warships in space, which might account for why the Bush administration were so keen to have him incarcerated in the States. In parts 2, 3 and 4 (below), McKinnon expands on the information shared in this first part (and gives his reasons for not believing in the moon landings, among other things). Many might be quick to label McKinnon a quack or a liar, but in this interview his body language doesn’t suggest he’s making anything up: in fact, during the course of the four-part interview, his story is remarkably insightful and consistent.

Description BBC to film a year in the life of an oak tree Dr Eric Casella from Forest Research (The UK Forestry Commission Research Agency) is working with the BBC on the production of a documentary which tells the story of an oak tree over a year of its life. Using innovative filming techniques, the programme will celebrate Britain’s most iconic tree, revealing its complex and fascinating biology and the lengths it goes to just to survive. Eric from FR’s Centre for Sustainable Forestry and Climate Change is working closely with Paul Sen and Nic Stacey from the FURNACE TV film and television production team. Eric says: “We visited the Wytham woods in January 2015 to laser scan a 400 year old oak tree as part of a scientific documentary coming to BBC Four in autumn 2015. The Production team wanted to film us scanning this fascinating tree and then show them the results with a fly-through animation of its three dimensional (3D) reconstruction from laser point-clouds. A laser scanner shoots out millions of pulses of light in every direction to make a 3D image of an object and its surrounding environment.” “This imaging technique is called Light Detection and Ranging (LiDAR). For each pulse fired, the laser records the 3D location to the first object detected on its path. At the end of this process all recorded points form the point-cloud that can be used to construct, for example, digital images and 3D geometrical models.” “By revisiting our tree in early 2015, when we’ll scan it again with no leaves, an accurate reconstruction of its woody structure will provide us with good estimates of its standing biomass and the carbon amount sequestrated during its life.” “It’s an exciting project for all of us and I'm really looking forward to seeing how the documentary turns out.” http://www.bbc.co.uk/iplayer/episode/b06fq03t/oak-tree-natures-greatest-survivor https://www.researchgate.net/publication/271325997_BBC_to_film_a_year_in_the_life_of_an_oak_tree Credits: Eric Casella (Scanning, reconstruction and animation making), UK Forestry Commission Research Agency http://www.forestry.gov.uk/forestresearch Eric.Casella@forestry.gsi.gov.uk - Paul Sen, FURNACE film and television production http://www.furnacetv.com - Nic Stacey, FURNACE film and television production - Nigel Fisher, Conservator of the Wytham Woods https://www.campaign.ox.ac.uk/wythamwoods - Helen MacKay, UK Forestry Commission Research Agency - Ian Craig, Forestry Commission Research Agency - The POV-Ray team http://www.povray.org - The Leica Geosystems team http://www.leica-geosystems.co.uk - Kevin MacLeod, http://www.incompetech.com for the Cool Vibes music track.
