Newsday, the suburban NYC newspaper has launched U Map NY. It includes opinion pieces, maps drawn by Common Cause of NY and an interactive map, which is based on...Dave's Redistricting.
I've been working with Newsday and Common Cause on this over the last couple of months. The application is similar to DRA, but has a new left panel in which you can switch between the Reform maps (from Common Cause and Newsday), the old maps and ones that you draw yourself. You start your own map from the Common Cause map or from a blank slate. When the state and suburban NYC counties produce their maps, those will be available, too. The idea for the left panel came from Newsday, and I really like it a lot. You can save your map locally and also on the Newsday server, where you can share with your friends.
Check it out.
