NC Geospatial Data Archiving Project

• Partnership between university library (NCSU) and
  state agency (NCCGIA), started Oct. 2004
• Focus on state and local geospatial content in
  North Carolina (state demonstration)
• Tied to NC OneMap initiative, which provides for
  seamless access to data, metadata, and
  inventories
• Goal Engage spatial data infrastructure (SDI) in
  data preservation and archiving

Demonstration repository as catalyst for an
industry conversation

Who?
4
Who?

• NCSU Libraries
• Capture at-risk data, demonstration repository
• Explore technical and organizational challenges
• Catalyze discussion, generate learning experience
• State/Local agencies, State Archives
• Data Producers Improved temporal data management
  practices
• Archives More efficient means of acquiring and
  preserving data progress towards best practices

5
Project Status
Who Commercial Data Producers and Vendors
Cultivating a commercial market for older data.
Part of permanent access is marketing,
advertising, and putting older data into the path
of the user
6
What?
7
What Traditional Geospatial Data Types
Raster/Image Data
Vector Data
Focus on Framework Data Layers
8
What Cartographic Products and Other Outputs

• GIS Software
• Software project file (.mxd, .apr, )
• Data layer file (.avl, .lyr, )
• PDF, GeoPDF map exports
• Web Services-based representations

9
What Place-based Data
Street Views
Oblique Imagery
3D Images
Tax Dept. Photos

• Present-day value in location-based services and
  mobile applications
• Future value for cultural heritage, descriptions
  of places

10
Why?
11
Why Solving Business Problems
Land use change analysis
Site location analysis
Real estate trends analysis
Disaster response
Resolution of legal challenges
Impervious surface maps
Suburban Development 1993/2002 Near
Mecklenburg-Cabarrus County border
12
Why Cultural Heritage and Emotional Connection
Pronounced local agency interest in archiving,
digitizing, and geo-referencing older analog
products
13
When? (and How Often?)
14
When Frequency of Capture Surveys

• How often should continually changing vector
  datasets be captured?
• Tap into data custodian understanding of
  production patterns and uses
• Tap into local innovation
• Learn about local business drivers for data
  archiving
• Survey subjects
• 2006 and 2008 surveys of NC cities and counties
• 2008 survey of archival practice in state
  agencies in NC
• Planned survey of data users in NC

15
When Frequency of Capture Surveys

• 2006 survey did more to socialize the problem of
  digital preservation within the data custodian
  community than any other project effort.
• Four points of engagement in survey process
• Survey formulation in consultation with advisory
  bodies
• Announcement of survey
• Survey completion by data custodians/producers
• Survey reports

16
Where?
17
Where Data Archive Locations

• In State
• Data producers Better temporal data management
• State Archives Selected authoritative records
• Libraries Derivatives and variants?
• Out of State
• GeoMAPP Project Multi-state exchange
• Participation in NDIIPP content exchanges
• Role for federal government? National Map?

18
How?
19
How Leveraging Spatial Data Infrastructure

• Data inventories support content identification
• Metadata standards support discoverability and
  use
• Content standards support data interoperability
  over time and help eliminate semantic confusion
• Data exchange networks
• Minimize need to make contact
• Add technical, administrative, descriptive
  metadata
• Establish rights and provenance

20
How Archiving as Part of Data Community
Discussion
Nov. 2007 NC Geographic Information Coordinating
Council (GICC) released Ten Recommendations in
Support of Geospatial Data Sharing

• Recommendation
• Establish archive and long term data access
  strategies
• Suggested best practices include
• Establish a policy and procedure for the
  provision of access to historic data, especially
  for framework data layers.

21
How GICC Archival and Long Term Access Committee

• Initiated in response to agency requests for
  guidance on temporal data management
• County, municipal, state, federal, and regional
  representation
• Key focus Best practices for data snapshots and
  retention

22
Moving Forward

• GICC Archival and Long-Term Access Committee
• GeoMAPP NDIIPP Multi-state geospatial project
  (NC, KY, UT)
• Open Geospatial Consortium (OGC) Data
  Preservation Working Group
• Vendor engagement
