Real estate mashup pulls listings from Google Base

Agent Earth maps properties on Google Earth application

Ownership of a new Google Base and Google Earth real estate mashup, called Agent Earth, is the subject of a dispute between a Chicago real estate brokerage company and a technologist who says it is an independent project.

Agent Earth maps properties listed for sale at the Google Base site on the Google Earth mapping platform, creating a new property-search tool that allows users to view properties on a virtual globe.
