Abstract: A computer system for locating real estate service providers by navigating an aerial image map of a geographic region. The system determines a search region corresponding to the geographic region by use of geospatial information associated with the geographic region. Once the search region is determined, the system searches a database for real estate service providers that are associated with the search region and that satisfy certain predetermined criteria.

Abstract: Under an embodiment of the invention, a web site system maintains a real estate web page. The web page has an aerial image map of a geographic region that can be navigated by a user. The web site system facilitates online collaboration for real estate transactions. When the user registers, the system creates a user account for real estate information. Real estate agents and/or other real estate service providers selected by the user are granted shared access to the user's account by the web site system.
