German Radar Satellite Lifts Off Tonight
2Y9D57 writes "Germany's new TanDEM-X radar satellite is scheduled to lift off from Baikonur Cosmodrome at 04:15 Berlin time on 21 June — that's 10:14 pm Eastern today (20 June). Flying in close formation with its twin satellite, TerraSAR-X, TanDEM-X will generate the most consistent and highest-resolution digital elevation map ever of the Earth — 12m = 40ft. pixel pitch. It will take three years to image all 150 million square kilometers (58 million square miles), in the process generating more than 350 TB of raw data. Here's where to go as the time approaches for live streaming."
Unfortunately, despite being partly publically funded by the German taxpayer, it appears the complete dataset will be considered proprietary for the commercial exploitation of Infoterra GmbH.
So, let me see whether I get this right:
Google taking street photos = bad (according to Germans).
The German government making high resolution elevation maps from space = good (according to Germans).
Where can I complain if I don't want my private property mapped by the German government?
It's launching in Europe on the 21st June but on the 20th in the USA. Why is the good shit always released in the US first?

At 40ft per pixel resolution, a normal 2 floored house will show as a single pixel above ground.
It's decent for SAR. Of course people have done *much much better* before. 40 feet for the entire Earth is a decent goal for civilian/commercial uses.
I've no doubt that they could've done much better. I suspect they didn't want to spend 20 years doing it.
and also Area 51A!
Poor rabbits...

that she can be identified on a 40 ft resolution height map.
No idea what other advantages radar has
It works through cloud cover and at night.
They can actually do much better, from what I gather on this site. Their highest 300 MHz high resolution spotlight mode will do down to 1.1x1.1 meter, but the main mode that'll sweep the earth is significantly coarser. Still in relative terms I must say the development here is huge...
Live today, because you never know what tomorrow brings
In the USA, all government works are in the public domain, which leads to NASA images and others being usable by the public and due to the copyright status, also by Wikipedia.
In Germany, a different concept was chosen. The general idea is that mostly private corporation want to use works by the government, e.g. publishers of books, maps, etc. In order to give a bit of the money spend on the works back to the taxpayer, everyone who wants to use those images has to pay royalties. This results in slightly less costs for the taxpayer, which is exactly the goal of that concept.
However, this approach is no longer viable. In the digital age, everyone is a potential user of works by the government, including works like maps and satellite images. NGOs like Wikimedia Deutschland (the German chapter of Wikimedia and supporter of the Wikipedia project) are lobbying to free those images. But the laws are, as usual, at least 10 years behind the technological and sociotechnical development.
