There and Then

I've updated my There and Then app. The update changes the design of the app to mirror the design of the Sky Map.

There and Then places a number of archive videos, taken from YouTube, and places them over the same view as seen today in Google Street View.

Updated Sky Map

I've updated the Sky Map to include all the astronomy videos on one map.

I've also made a couple of other design changes. You can now navigate to the different videos by clicking on the thumbnail images at the bottom of the map. It is also possible to remove the video from the map by clicking on the 'video layer' button (just click it again to bring the video back).

The videos can be controlled via the buttons positioned at the right of the screen.

Google Sky & Chromeless Videos

It is possible to create a pretty impressive effect by embedding chromeless videos in Google Maps. I've put together a number of examples here.

The maps show a number of astronomical animations overlaid on top of Google Sky. I've used the YouTube API to show the videos in a chromeless player. The effect is pretty cool, creating an almost seamless overlay of the video on the map.

Nuclear Exclusion Zone

20km Exclusion Zone - Comparison Tool

Japan has ordered a 20km (12 mile) exclusion zone around the Fukushima Daiichi nuclear power plant. Those living between 20km and 30km have also been told not to leave their homes.

I've created this Google Map to show the exclusion zone around the power plant. You can also use the search option to see what a 20km exclusion zone would look like at any other location around the world.

If the center of the zone doesn't exactly match your address you can also drag the marker to the location of your choice.

I've also added 33 serious nuclear power plant accidents around the world since 1952. The data comes from a Fusion Table created by The Guardian's Data Blog.
