Abstract
Data Snapshot Archiving: A Frequency of Capture Survey Track: Metadata and Data Publishing Author(s): Steve Morris, Jeffery Brown, Jeff Essic Many of the framework vector data layers managed by county or municipal GIS agencies are intermittently or continuously updated. Increased interest in applications and analysis related to land use change, real estate trends, and site location are driving demand for older versions of data. ArcGIS 9.2's time animation tools are expected to further increase interest in archived data. The North Carolina Geospatial Data Archiving Project is a Library of Congress-funded effort focusing on the problem of long-term preservation of digital geospatial data. In order to seek guidance about optimal frequency of capture for key framework data layers, a survey of county and municipal data management practice was conducted. The survey addressed general data archiving practices (separate from routine backups) as well as specific data management issues related to parcels, street centerlines, jurisdictional boundaries, and zoning. The survey results and the implications for forming data archiving best practices will be discussed.
