1. Preservation of Geospatial Data Kenny Ratliff, DGI and Glen McAninch, KDLA April 22, 2008 Digital Technology Summit Lexington, Kentucky

2. Problem Statement Most current data mindset –What did it look like yesterday? 5 years ago? Burden on individual agencies to capture –Are they aware? Being done? Storage and access of captured data –Where? Backed-up for business continuity? DGI Mission Facilitate statewide electronic geographic data sharing and its application for streamlined decision-making, greater efficiency, public protection, and economic vitality.

3. Kentucky Geography Network Contains 373 layers for use in GIS

6. Uses 29 layers from the KyGeoNet

7. Uses 152 layers from DGI holdings

8. Vector Information Polygons –Cadastral (tax parcels) – Zoning –County bounds –Voting precincts Points –Schools –Hospitals –Shelters Lines –Street centerlines –Rivers / streams –Water / wastewater systems Many others…

9. Value in Older Data: Solving Business Problems Suburban Development examples Land use change analysis Real estate trends analysis Site location analysis Disaster response Resolution of legal challengesImpervious surface maps

10. Raster Data (KLC)

11. National Digital Information and Preservation Program (NDIPP)

12. Expectations – Scope of work –Identify archival GIS layers / applications –Examine approach of other states –Install hardware and software –Identify archival meta data including retention for input into clearinghouses –Capture selected layers for archiving –Test methods for sharing of data among the states –Write a report on findings and experiences –Work with Kentucky and national professional organizations

13. Records Retention Schedule The system is scheduled as a permanent record and all image files are saved permanently. Copies come to the archive even when they are still in the system. Selected vector files which are determined archival are saved via periodic capture and transfer to archive server as part of regular system updates Vector data from each contributing agency is evaluated in the context of all agency records.

14. Repository Goal Capture at-risk data Explore technical and organizational challenges Project End Goal Data Producers: Improved temporal data management practices Archives: More efficient means of acquiring and preserving data Stewardship: Repository as Catalyst for Conversation

15. Data Grid Technology for Sharing Manage data residing in heterogeneous storage systems –Storage repository virtualization –Support new storage systems while moving data from old storage systems Manage data distributed across multiple storage systems –Data virtualization –Replication of data for fault tolerance and disaster recovery Data grids manage information about files as well as the storage
