digital maps on the Web . The Assessor contracted ESRI to help in the development of PAIS , which includes data from Rand McNally's Thomas Bros . Maps and the County Department of Public Works and a link to the Treasurer-Tax Collector's Web page . "The Web site lets a real estate agent select a subject property and then buffer out 500 and 1 ,000 feet or one-fourth , one-half, and one mile to identify all properties that have sold in the past two years , ' says Steve Trammell , ESRI cadastral solutions manager. " Real estate professionals account for a significant amount of the public service counter traffic because they are looking to establish acceptable buying and selling prices on a property." According to Trammell , a real estate agent can identify comparable properties (with similar square footage, bedrooms , and baths) to determine a baseline selling price . These professionals would normally have to telephone the Assessor's Office or visit the Registrar- Recorder's Office to get this kind of information . PAIS features a seamless GIS parcel map base with links to scanned versions of the actual hard-copy assessment maps. The response time on the 2.3 million parcel GIS database is very quick, and users can quickly link to a scanned map for legal description information and lot dimensions . "It 's an example of true public access with ArclMS providing the technology architecture for access to very detailed map data ," adds Trammell . "This is a very successful site and represents a huge savings in public counter labor costs ." " In October 2001 , there were four million page views with 1 . 4 million map requests . This represented 80 ,000 actual visits to the site by 20, 000 unique visitors . » For more information , contact Richard Quacquarini , chief cadastral engineer, Office of Los Angeles County Assessor ( tel . : 213-974-7351 , e-mail : rquacquaodco .la . ca . us ) . *Case Study Courtesy of ESRI ArcNews Magazine GIS Data Layer Inventory and Recommendations The Property Appraiser' s Office will benefit from access to several other departmental GIS data layers .
