When we launched our new main map on the front page of maps.safecast.org we mentioned that was just the first step in an ongoing process aimed at providing better, more useful info. We’ve recently added another feature to it – data for each grid. If you click on any gird element you’ll now see information about the highest and lowest readings taken in that quadrant as well as the date ranges of those readings. We’re excited about this and think it’s an excellent step forward from what we had, and that much closer to what we hope to have soon. It’s live now, so please feel free to check it out.
