2. NCSU Libraries NC Geospatial Data Archiving Project Partnership between NCSU Libraries and NC Center for Geographic Information & Analysis State and local geospatial content in North Carolina Tied to NC OneMap initiative, which provides seamless access to data, metadata, and inventories Engage existing state/federal geospatial data infrastructures in preservation

3. NCSU Libraries Geospatial data types: Vector data Time series Parcel Boundary Changes 2001-2004 North Raleigh, NC

4. NCSU Libraries Geospatial data types: Aerial imagery

5. NCSU Libraries Geospatial data types: Aerial imagery

6. NCSU Libraries Geospatial data types: Aerial imagery 85+ NC counties with orthophotos 1-5 flights per county 30-200 gb per flight

7. NCSU Libraries Today’s geospatial data as tomorrow’s cultural heritage Future uses of data are difficult to anticipate (as with Sanborn Maps).

8. NCSU Libraries Geospatial Data: Risks Producer focus on current data Future support of data formats in question Shift to web services- and API-based access Inadequate or nonexistent metadata Increasing use of spatial databases for data management

9. NCSU Libraries Different Ways to Approach Preservation Technical solutions: How do we archive acquired content over the long term? Cultural/Organizational solutions: How do we make the data more preservable—and more prone to be archived—from point of production?

10. NCSU Libraries Technical Approach: Progress Ingest workflow –Receiving data as is – variety of distribution methods –Migration of some at-risk formats –Metadata remediation, standardization, and synchronization –Mechanism for distilling complex objects into repository ingest items Repository –Using DSpace for demonstration purposes –In development: use METS record as dormant item “brain” within the repository

11. NCSU Libraries Organizational Approaches: Progress Engaging spatial data infrastructure –Feedback to metadata outreach program –Feedback on adherence to content standards –Involvement of state and local advisory bodies in project –Viral approach to promoting digital preservation Engaging industry –Working with software vendors (e.g, ESRI) –Engaging standards community (Open Geospatial Consortium)

12. NCSU Libraries Changing Thinking Web 2.0, web mashups, and AJAX technologies create new opportunities (and challenges) –Looking at static, pre-cut image tiles from geospatial web services as a preservation target “Contact fatigue” among local agencies—need to work with state agencies on coordinated flow of data –Participating in a collaborative multi-agency effort to routinize content exchange

13. NCSU Libraries Learning from the NDIIPP Network Maturing thinking about metadata transformations (inspiration from the UIUC/OCLC “hub and spoke” model) Leveraging outside expertise in preservation metadata (interactions with Stanford NDIIPP project) Discussions about mutual use of tools in ingest workflow (JHOVE, ClamAV, noid, MD5, etc.) NDIIPP network creates opportunities for interactions that might not otherwise happen Jim Tuttle, NCSU Libraries jim_tuttle@ncsu.edu
