However, the City of San Mateo lacked a single complete, accurate, and current address list that could be used as the authoritative source of business and residential locations. This situation limited the ability for City departments to coordinate efforts and integrate information across business systems.

Farallon Geographics designed and deployed a Master Address Database (MAD) that could be used as a central authoritative service by all authorized City departments. The MAD was deployed using the City’s SQL server database accessible over an Intranet website and integrated with the City’s existing Intergraph GeoMedia geodatabase.

Using the MAD interface, authorized City staff including non-GIS users can search for addresses by street name and/or number, Assessor Parcel Number (APN) or the owner’s name. In addition to the list of valid addresses, results also include a display of a street-level map showing the location of the address within the City. Simply by clicking on the map, users can mark any address within the MAD as needing review or request the addition of address points. The site’s web mapping functionality uses Microsoft Virtual Earth which allows high-performance viewing as regular maps, ortho and oblique aerial images, or in 3D. Virtual Earth will also permit display of other non-address data such as ownership name or environmental planning data.

Farallon’s MAD implementation offers the City increased data availability, reduced errors and maintenance, elimination of costly duplicate data, and enhancement of City services. It will be used as a reference for Public Works and many other City operations such as Police and Fire Departments. Referring to the MAD, Patrick Crevelt, GIS Coordinator with the City of San Mateo, notes, “I am very pleased with how it has turned out and am excited about its use throughout our organization.”
