KML is a file format used to display geographic data in a tool such as Google Earth or Google Maps. KML is an international standard maintained by the Open Geospatial Consortium, Inc. (OGC).
These KML files are prototype files to help us gauge demand and gather requirements in order to build a product that is useful to our users. These KML files are compatible with tools such as Google Earthand Google Maps.
Layers Available: Counties and Census Tracts
Attributes: Geographic Identifier (GEOID)
Vintage: 2010 Census
Available in Detailed (the exact boundaries) and Generalized (boundaries are smoothed and do not represent the exact boundaries)
We are reviewing the comments we have received and are evaluating how to best implement a tool that allows you to access KMLs. We expect to have an update as to how we plan to implement the production and release of KMLs in early 2013.
