About C-SPAN Video Library

Map Information

The C-SPAN Video Library uses Google Maps to visualize data regarding congressional districts, states, and event locations. National, state, and district borders appearing on these maps have been simplified due to size and bandwidth constraints.

District and state borders that appear on the Video Library were derived from datasets at the U.S. Census Bureau website.

National borders that appear on the Video Library were derived from a dataset at thematicmapping.org. The source dataset is available under a Creative Commons Attribution-Share Alike License.
