New Visualizations


One of our goals at Safecast, in addition to collecting radiation data, is putting that data into a format that is helpful and useful. If you’ve been following our work for the last few months you’ve seen the map we launched with on day one progress through several evolutions including being split out into several specific purpose versions. We’ve just launched a new revision to these and now have a maps specific URL we’re we’ll keep all the mapping visualizations we’re producing. Please take a look at

What you’ll see there:
Safecast Map: This depicts over 500,000 radiation data points collected by the Safecast team throughout Japan. For each square, numerous geiger readings have been collected and color-coded. This is our main map and the one we’ll be tweaking and improving on a very regular basis.
Full Data Set Map: While the Safecast Map simplifies the readings into a general grid, the full data set map actually shows you each and every point we’ve collected. It’s very dense, but if you want to drill in this is where you can do it. This collected data set will be available for download in the near future.

Drive Maps: Both of the above maps are based on data we’ve collected driving around with out bGeigie sensors. If you want to see an individual drive on it’s own check out the Drive Maps, you can also download a CSV file for each drive to play with the data yourself.
Fixed Sensor Network: We’ve been working with our partners at Keio University’s Scanning The Earth project to build a network of fixed sensors, and this maps shows the data coming in from those devices we’ve installed out in the field. STE has a great historical visualization of these points, and Yahoo! Japan has just release their own map using the data we’re providing from these devices.
Aggregate Map: We also still have the original Aggregate Map showing all the data we’re scraping from other sources.

While these are our newest maps, they are by no means our final versions and we’ll continue to edit and improve these as our work continues – that said we think these are a step forward from our last versions, and hope our next step will be an improvement to these. We know there are some missing legends and a little better explanation of what the colors/points mean and hope to have that up soon, but if you have any other feedback, requests, comments, concerns, etc please let us know.
