The Boneyard
This was just too cool not to blog: The Boneyard. Have a read of the story over at the BBC. Great stuff!

SRTM 10th Anniversary
Yes, believe it or not, SRTM is celebrating it's 10th anniversary. If there is perhaps one NASA mission that has had such a profound impact upon Earth Sciences (and certainly with respect to the number of days "in space") then this is it. Relatively high resolution topographic data of most of the planet's landmass, available for free, is a amazing achievement. ASPRS Photogrammetric Engineering and Remote Sensing had a special issue devoted to SRTM back in 2006 and the lead cover article (which is free) provides background to the mission. It truly amazing achievement based on this account.

Infrared Photography
There's a nice summary article covering infrared photography over at the BBC. It's part of the celebrations of 100 years of infrared photography. If you read the article you'll see that infrared has been known about for at least a further 100 years, but getting photographic film/plates that were sensitive to these wavelengths was difficult. That occurred around 1910, with commercial film from 1930.

Snow covered UK
It's already been flagged up on the BBC, but a Terra MODIS image captured a nearly cloud free, almost totally snow covered, UK yesterday. It's quite simply stunning and is available from the MODIS Rapid Response System which provides near real-time access to MODIS imagery on Aqua and Terra. This particular image is the highest resolution (250m pixels) version and is available with a worldfile meaning it can be loaded straight in to a GIS.

Plummeting winter temperatures mapped
Nice example of environmental monitoring over at NASA, this time using MODIS Land Surface Temperature to compared temperatures in Europe this winter (11-18 December) with the 2000-2008 average. The UK is a little cooler than "normal"; the real problem areas are Russia, Scandinavia and Poland, with parts up to 20C colder than previous years.

Happy Birthday NASA Terra
NASAs Terra is now 10!! Launched to much fanfare in 1999, of interest to Earth scientists it carries MODIS (wide swath, medium resolution, super spectral) and ASTER. The latter also being super spectral, but high resolution (upto 15m) and also stereoscopic. Note the earlier post on the recently released global DEM product. An extremely successful mission and the celebration pages show some fantastic examples of environmental change.

Open Topography Portal Expanded
As reported by lidar news, the Open Topography Portal is to be expanded following a grant from the NSF. The OTP provide a valuable service, albeit somewhat small at the moment. However growing interest in point clouds and DEMs are driving interest and so its excellent to see further investment like this.

Low Cost LiDAR
Lidar news have a nice article on low cost 2D LiDAR. Well worth looking at the OXTS webpage and related videos. This clearly demonstrates how young the mobile LiDAR (and for that matter static LiDAR) area is so expect to see big strides to making it more cost effective.

UK Space Agency
Great news this week with the announcement that the UK is set to have a space agency and hopefully begin to capitalise on its rapidly increasing expertise in this area. Spaceman has a good blog entry on this and the BNSC's linked Space Exploration Review is well worth downloading and leafing through.

EO-1 Open for Tasking
After the news last week of the death of TopSat, it is good to see that NASA have opened up EO-1 for tasking. EO-1 was "launched on November 21, 2000 as part of a one-year technology validation/demonstration mission." Its been very successful and lasted considerably longer than most thought. It carries the ALI multi-spectral (10m Pan and 30m MS) and Hyperion hyperspectral (220 30m bands) sensors. If you are in need of data then visit the Data Acquisition Request page and submit a request; this will be reviewed and, if deemed appropriate, tasked.

Get your own satellite in to orbit
You've heard of personal computers well now it's time to own your own personal satellite. Space Fellowship has a nice story on tube satellites. For $8,000, yes $8,000 (!), you get to place your own satellite in to a decaying orbit. It last for a few weeks, but this is no toy. The kit includes the satellite’s structural components, safety hardware, solar panels, batteries, power management hardware and software, transceiver, antennas, and microcomputer and as long as it stays within the 0.75kg weight limit you can design your own experiment including, for example, remote video monitoring. Plenty of scope for some innovative amateur work here.

OGC 3D Fusion Summit
Lidar News reports the OGC 3D Fusion Summit next week, rightly noting that
"This is being billed as a first of its kind event in North America, bringing together many of the major technology players in 3D and related topics."
Lidar is really hitting it big time and their are all many key players coming together. Whilst we have LAS as a file format and ESRI entering the fray with terrains, some standardization is sorely needed. Hopefully the OGC can provide this in the same way it has for other areas; the 3D Information Management (3DIM) Working Group seems to be the right starting point.

NextMap on iPhone
Intermap are finally moving in to the consumer arena with the release of Accuterra, an iPhone app that offers terrain data (and other info) for off-road users. This was noted by All Points last week and they point out that the app is not streamed, but downloaded to the users phone. You buy a single tile which is 200-400 Mb in size. Meaning of course when you are out of range, the app carries on working. It'll be interesting to see how popular it proves.

GPS Failure?
Tidbits are reporting on the potential for a degradation in GPS accuracy over the next 2 years. The basis for the article is a recent Government Accountability Office report on the US Air Force satellite replacement program for GPS which is behind schedule and over budget (nothing new there then for the military!). However a risk analysis is highlighting the likelihood for the constellation to drop below 24 satellites potentially reducing accuracy. And, if over runs continue, the risk of a failure of the system. Not much to do but watch and wait, but clearly it's a highlighted risk.

IKONOS Data licensed by ESA
Interesting news over at Mundogeo announcing the licensing of IKONOS imagery by ESA. The interesting aspect is, to quote the article:
"Ikonos as a Third Party Mission is available to Esa and Esa-approved projects for scientific research, applications development, or research and development in preparation for operational use in future, the so-called Category-1 use."
Which means that an ESA approved project can have access to IKONOS imagery. Potentially a very useful source of data.

The ASPRS have been hard at work converting some of their old video footage of things remote sensing and turning them in to short "info-clips". Its a worthwhile exercise and they have a YouTube channel where they can be viewed. Worth a look.

KAP Photogrammetry
I was recently in touch with Ryan Strynatka, the product manager for ERDAS' Leica Photogrammetry Suite, over my recently published paper on photogrammetry using vertical imagery from a kite. He was interested enough to write a summary which is worth a read. And, if you haven't come across his blog, it's worth following as he regularly updates it with all things photogrammetric.

Super-duper-Zoom
192.com have launched a beta version of their "Super Zoom" aerial imagery. I saw this on Mapperz last week and thought I would check it out. And yes, the UK is covered at 12.5cm (no surprise there) and central London at 4cm (although their press release doesn't actually state the resolution, the date of acquisition or where the imagery came from)!! The Guardian have a thoughtful piece on the privacy implications. They interviewed 192.com's CEO and note the 4cm resolution, flown during 2007 and licensed from the OS. Anyway, the data itself is amazing and well worth a look.

Landsat 5 back imaging again
Back in September 2007 the USGS reported problems with Landsat 5's onboard batteries which had caused it to stop imaging. Landsat 5 has proved really rather remarkable, proving very reliable since it started imaging in March 1984 (and completing its 125,000 orbit last year). It still provides Thematic Mapper imagery (at 30m resolution) and, almost single-handedly, has been NASA's "Mission to Planet Earth." Anyway, the USGS happily reports that the fault has been found and imaging is now back online. Testing is continuing to see how the satellite performs.
