If you are interested in the ongoing deevlopments with the newly established UK Space Agency then some details are being made available on their website. Some details on the current transition plans are available here and info on the International Space Innovation Space Centre (ISIC) at Harwell is given here. This of course may change as a result of forthcomng government spending review, but let’s hope the Agency does not stall now.
A date for your diary. The 11th International Circumpolar Remote Sensing Symposium will take place in Cambridge, UK, from 20th to 24th September. This conference deals specifically with remote sensing applications in Arctic and Antarctic polar environments. The conference venue is SPRI and more details are available here.
Tandem-X, the partner satellite of the German TerraSAR satellite, was successfully launched today. It will now fly in formation with Terrasar, another synthetic aperture radar (SAR) satellite, and collect data from which a detailed elevation model of the earth surface will be generated. Uniquely this system will be based on SAR interferometry techniques and is therefore not hindered by cloud or surface texture factors.
The end goal is a global, detailed and accurate elevation model free of the anomalies present in current datasets such as G-DEM. It also promises to be more detailed with pixel spacing of 12 metres. For comparison see the graphic below and consider that SRTM provides data at 90m resolution and G-DEM at 30m. Of course in polar regions we will suffer from the usual data gap at extreme latitudes, but an orbit inclination of ~98 degrees means coverage for almost all steep terrain in the Antarctic, only missing parts of the Trans Antarctic Mountains.
The global elevation data is expected to be available in 2013 and will be distributed by Infoterra, but more news here if any coverage is available before that date. No details on data licence and costs yet.
More information is available here and a video showing the formation flying is available here.
One of the advantages of having very frequent ESA Envisat SAR imagery in the Antarctic is being able to keep a close eye on large icebergs that might cause problems such as restricting access, impact on wildlife or navigational hazard. Add to that list the consequences of hitting an iceshelf, especially when it is home to one of your bases, and it’ s a good idea to keep an eye open.
One such iceberg, lovingly named the B15K, has been loitering around the Brunt iceshelf over the past couple of weeks. Any risk to the Halley base now appears to have passed, but the regular images were a useful part of the monitoring in place to track any changes to the Brunt.
Second time lucky. CryoSat2 was successfully launched yesterday from Kazakhstan following the failure of the first attempt in 2005. The remainder of the Launch and Early Operations Phase will continue over the coming weeks before data will begin to be disseminated. More details are available from ESA and the BBC.
That brings to three, the number of satellites launched as part of the ESA Earth Observation programme with CryoSat2 following earlier successful launches of GOCE and SMOS. Jonathan Amos gives a good overview of just what rude health the European EO sector is currently facing which is well worth a read in the afterglow of yesterdays launch.
The Polar View Antarctic service is now providing interpreted sea ice charts produced by the Norwegian Meteorological Institute. In the high-bandwidth map view, users can now select the ‘Ice chart by met.no’ tab to display the latest chart. A number of options for download are then made available on the right-side of the viewer including OGC compliant WMS. The simplest option however is the permanent link to the latest chart as a JPEG graphic.
These charts will be compiled on a weekly basis and currently cover from the Fimbul Ice Shelf, across the Weddell Sea, to west of the Antarctic Peninsula. They are compiled using the most up to date AMSR-E passive microwave ice concentration data and ESA Envisat ASAR imagery.
It’s finally here. The new UK Space Agency was officially unveiled today, including the official name, new logo and a few more details about plans for the future and what funding will be included. Read more here on BBC. So here’s looking forward to the coherency promised by this devlopment and effective engagement by all partners to ensure EO makes the most of this opportunity, including the developments at the International Space Innovation Centre (ISIC) at Harwell.
Quickly highlighting a stunning image of the UK currently with very little not under a blanket of snow. The image is from the MODIS instrument (notice NASA first port of call again) and it is worth highlighting the recent improvements to the MODIS Rapid Response site. At first glance they look relatively minor, but the layout of quicklook images in a geographic pattern makes locating the required image much easier. Chapeau!
