Madison - September 28, 2012: Ballotpedia and Moonshadow Mobile, Inc. have released a second round of Congressional and legislative district comparative maps for 2012 election coverage in 30 states.

Using proprietary technology and data supplied by Labels and Lists, Inc., Moonshadow has created maps comparing districts before and after the redistricting process, showing the old (2001) and new (2011) lines for U.S. Congressional districts as well as state legislative districts. The most recent round of maps highlights Congressional districts, state Senate districts and state House districts where the partisan registration difference between Democrats and Republicans is less than 10%.

Ballotpedia has incorporated these maps into their coverage of the statewide elections in Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Illinois, Indiana, Iowa, Kansas, Maryland, Michigan, Mississippi, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Virginia and Washington.

About Moonshadow Mobile, Inc.
Moonshadow Mobile, Inc., based in Eugene, Oregon, has developed Internet technology to instantly visualize "Big Data" inside of Bing Maps or Google Maps. With Moonshadow's patent-pending technology databases with hundreds of millions of records can be visualized within seconds in the cloud. Moonshadow's technology can visualize close to 100 million records per second per processor core which is roughly 100 times faster than traditional databases. With Moonshadow's technology organizations can provide interactive access to large databases in a mapping environment. Data is shown on maps or satellite images instead of tables. This makes it easier to access and understand big databases and it leads to a much better user experience. Moonshadow's visualization technology is now used in a variety of products such as VoterMapping (political campaigns), CensusViewer (demographic analysis), ConstituentMapping (government access to data), Ground Game (mobile canvassing) and Borderline (redistricting). It is Moonshadow's mission to change the way people access, understand, analyze and work with data.
