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.

Consultation on release of OS data
As reported by FoD and Mapperz, DCLG have begun the consultation concerning the release of OS data. There is an accompanying impact assessment. Well worth leafing through both.

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.

ERDAS goes where ESRI fears to tread
Slashdot reported earlier this year on the FOSS4G web server benchmarking. The big news was that ESRI were taking part, but then pulled out. The hope was to get both ESRI and MapGuide in to the frame to see how they did. With the recently announced ERDAS 2010 released, Chris Tweedie over at ERDAS took it upon himself to run some benchmarks (also reported in Slashdot). The results certainly look impressive (up to twice as fast as Mapserver) which I guess is why they were happy to put the product forward. ESRIs silence is deafening....

DMC 22m Multiispectral Data Available
Slashgeo report on the availability of 22m multispectral data from DMC via the UK-DMC2 and Deimos-1 satellites. Good to see this constellation is proving successful and improving; a great advert for the new British Space Agency!

Christmas Every Year?
I'm sure this is a result of "middle age grouch" syndrome hitting me, but the whole "Christmas thing" seems to get bigger, earlier and glitzier each year. How refreshing to see this petition to number 10. Shame its lapsed as I would have voted!!!!

A Practical Guide to Geostatistical Mapping
Tomislav Hengl has just published an open-access book on geostatistical mapping. The PDF is freely available with the printed version very modestly priced. The website links to datasets with the analysis performed in R, ILWIS and SAGA, whilst the book itself comes out of the courses he teaches at ITC. Well worth a look.

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.

USB3 is here
PCPro have published some results of the first USB3 devices to hit the market. Motherboards with USB3 ports are yet to arrive so you have to make do with PCI Express cards, but they're cheap at under £30. Clearly this will be a boon to external HDDs, portable media, external monitors etc etc and data transfer rates appear to be 2-4 times faster. As previous posts show, I use a portable HDD wherever possible for storing data and running apps, so USB3 is a big deal. I'll be on the look out for a USB3 drive caddy ASAP!

Postcode data release proposal
The BBC reports today that the government is planning to release postcode data early next year. This is good news as postcodes underpin so much dynamic geospatial datasets. Their commercialisation has been wrong from the outset when you have public services such as the Royal Mail and OS trying to make as much money out of data ostensibly provided by local government (but with value added). It would appear that a short consultation process across all organisations due to release data will be begin. Early next year will prove an interesting time as we see what is released and then how it is made use of.
