Radar images of earth
August 13, 2007 8:08 AM   Subscribe

High resolution images of Earth. The German satellite TerraSAR-X was shot into space on June 15, and already four days after sent some beautiful pictures back to Earth. Pictures are described in German, but you'll figure it out.

Wie werde ich es lösen wenn ich nicht weiß wie zu lesen oder Deutsch zu schreiben?

Oh wait...

I'm not clear on how this is any better than the existing imagery from Google Earth, etc... and with it being European I'm skeptical that the public will get access to an image database.

They are radar images. Resolution is limited by wavelength and radar wavelengths are much longer than optical ones.

Data from this satellite (and its sister satellite to be launched in a couple of years) will include detailed topographical data, enabling true 3D representations of the earth (with colour-corrected images on top) - both to the surface and including vegetation and man-made structures. There are other ways to go about this not involving satellites, but in theory at least, this is the cheapest and quickest way to do it. To the the difference between high quality and low quality 3D maps, check out the UK (especially those mountains in Wales) in Google Earth and MS Virtual Earth. MS has detailed IFSAR maps (from high-altitude planes) while Google has lower quality 3D data.

And the "public" will not get access to it (as far as I know) - this is a private corporation owned by EADS. It will be sold to governments, PND OEMs, car makers, mapping and software cos and insurance companies.

that's unfair

Apparently not, seeing as I'm just seeing a big white box where I assume content should be.

Try this link from the company's website. Bonus: It's in English.

Decreasing or increasing the font size (top right) solved this for me.

Thanks for that link loquax, it seems my posting this without checking for some English pages with those pictures was too hastened.

Basic info on SAR (Synthetic Aperture Radar) imagery here. More interesting links on that site, including a pretty cool archive of images from all sorts of SAR platforms.

Ooooo I loves me a new remote sensing platform!

Wait, what? I thought those dirty Europeans were all about big government and social welfare, and it was the America that did things better with its free market and private corporations. Jetzt bin ich ganz verwirrt.

No no, the weird thing is moonbiter, because Americans are all so down on government and socialism, when the government does pay for something or do something, people kick and scream and demand free access for their tax dollars.

Whereas elsewhere, we tend to have to deal with bullshit "cost recovery" payments whenever we want to try to get any kind of data out of the government. In my experience, the US makes a lot more of it's data (for things like meteorology, maps, environmental data) available for free to the public than in Europe or here in Australia.
