Once in a while a piece of software comes along and just blows my mind – lately it’s been NASA’s World Wind software which has captured my imagination. This amazing software uses NASA Landsat 7 satellite images to let you zoom in to almost any place on the globe and view the surrounding area in 3D. It also allows you to play around with lots of scientific information for visualization of weather systems or temperature data.

The very best thing about this is that it’s totally free of charge to download and use. Be warned though – the data it needs will require several gigabytes of diskspace and you’ll need a decent internet connection (512kbps+)(or a lot of patience) to be able to download all the data for the high-resolution images. But it’s still worth it to be able to explore countless places around the globe from the comfort of your home!
