Gigapixel 360 Panorama from Gale Crater on Mars

The Curiosity Rover on Mars has been busy taking pictures. About 405 of them with the two cameras on the vehicle's mast. These have been combined to produce a spherical panorama measuring 90000x45000 pixels (or 4 billion pixels). The result is a stunning spherical, gigapixel image of the Gale Crater

For those who want the technical details, this was taken betwen Martian solar days 136-149
using both the 100mm Narrow Angle Camera (NAC), and 34mm Medium Angle Camera (MAC). Though not the largest Gigapixel image ever produced, it is probably the most amazing in terms of technical achievement. 

Though you may not be able to produce an image of this kind, you can get yourself a bit of the Mars mission. Ok, so it would be in Lego, but someone has put together plans for how to build your own Lego Curiosity Rover and landing stage

Largest Gigapixel 306 Panorama Ever Shows London from BT Tower

BT now own the largest 360 panorama in the world. Taken from the top of the BT tower during the London Olympics in 2012, it shows of the heart of the city. To mark the event BT have hidden 3 images of their Buzby mascot within the image. The lucky finders will receive prizes. It beats the 80 gigapixel image of London released in 2010 by quite some distance.

This 320 gigapixel image was created by stitching together some 48,640 individual frames taken with  four Canon EOS 7D cameras. It is hosted by 360 Cities. The image is most impressive in the mid-distance range as the day on which it was taken is quite hazy resulting in loss of clarity at long range. As with all images of this kind, there are increasing stitching errors as one gets closer to the tower, and the office buildings nearby are suffering some a degree of 'flexability'.

All the landmarks are clearly visible, and by the looks of the scarring on the lower end of Regents Park, it would appear that an exhibition event has just left the park. 

A collection of over 300 panoramas taken around the city, linked to Google Maps, can be found on this London virtual tour map.
