Blue Marble NG – Google Earth (Rendered) SuperOverlays

Yes I know, its another way to view Blue Marble Next Generation imagery in Google Earth, but here Jonathan van Tuijl has taken the time to pre-process the full resolution 500m/pixel imagery into static files, meaning that hopefully the loading should be smother (at least when accessed from this side of the Atlantic!) and more refined as a its not relying on a server to dynamically generate the KML and images (even if it then caches it), as done here. We also hope to make available the full range of Blue Marble layers.

… doesn’t do any of the fancy fading out like the version here, which is designed to be left running :)

See the post in the KML group that started this little adventure, which I believe started as an exercise for Jonathan to find a way to slice up really large images, and generate a Google Earth SuperOverlay from that; as none of the ‘packages’ seemed to be able to manage it (I’ve tried it too!). So I joined in offering hosting – as think its a neat exercise in hosting really large datasets (7.4GB at last count) – now I have a powerful server. (famous last words…)

  1. [...] Check it out! While looking through the blogosphere we stumbled on an interesting post today.Here’s a quick excerpt [...]

    I enjoy coding things like this once in a while. It was actually done in part to top what I did with the original 43200×21600 Blue Marble a few years ago, when I wasn’t as good at programming, which was to scale it to one size. Now I scaled 36 86400×43200 images to 7 sizes with better resampling. :-)

    The size of everything is about 16.5 GB, not counting the space tiny water (solid color) files don’t use in their file system block.

  3. [...] I notice Jonathan has finished uploading all 36 layers of the Blue Marble Next Generation imagery, that he has been processing for viewing in Google Earth. These are the full resolution imagery available, at an impressive 500m per pixel I believe, and preprocessed for reasonably quick loading – shouldn’t be *that* much slower than GE’s built in imagery.
