Résumé en anglais
The effective management of information about historicresources is essential to their conservation and protection. As part of
a larger project to develop a citywide historic resource surveymethodology for the City of Los Angeles, the Getty Conservation
Institute (GCI) examined data systems and Geographic InformationSystems (GIS) that have been implemented in North America cities.
Existing systems are broadly classified into three main types:parallel, dispersed, and centralized. A parallel GIS runs parallel to
and entirely separate from a city’s existing infrastructure, planning,and zoning GIS. A dispersed GIS is also an entirely separate system,
but with a formalized data transfer protocol between the historicresource GIS and the city’s primary GIS. With the centralized GIS
approach, a city builds and maintains a single, central GIS that servesas the hub for all of its infrastructure, planning, zoning, and historic
resource data. Each type is illustrated with examples herein and theadvantages and disadvantages are highlighted
