1 NDIIPP Project Update NC Geospatial Data Archiving Project (NCGDAP) North Carolina State University Libraries North Carolina Center for Geographic Information & Analysis Presented by:Steve Morris Head of Digital Library Initiatives NCSU Libraries NDIIPP Partners MeetingJanuary 17, 2007

2 A “temporally-impaired” industry begins to discover time and the value of older data Major vendors and consulting firms begin to see temporal data management and analysis as a customer problem Opportunities abound to engage professional organizations, software vendors, data producers, standards organizations Biggest Project Surprise: Emerging Industry Interest in Data Longevity

3 The true counterpart to the old map is not the GIS dataset but rather the finished geographic product (map, chart, etc.) More than data—also classification, layering, symbolization, annotation, modeling … PDF documents are an increasingly common output format for finished products Unexpected Activities: Handling PDF as a Geospatial Format

4 County and city agencies beginning to digitize old maps and aerial imagery NCGDAP partners with NC Geologic Survey to resurrect geologic maps and old topo maps NCGDAP-georectified maps made available for download and put in the National Geologic Map Database in 2006 Unexpected Activities: Resurrecting Old Maps Superceded USGS Topo Maps Geologic Maps from Theses, Dissertations, and Reports

5 Survey indicates that 20 state agencies are asking for local geodata “Contact fatigue” among local agencies – in response state/local/ federal data exchange partnerships emerge Leveraging more compelling business reasons to put the data in motion Unexpected Activities: Partnering in Content Exchange Networks Orthophoto “sneakernet” system Started fall 2006 Transportation data exchange system Funded starting fall 2006 Ongoing statewide data inventory Started March 2006

6 Unexpected Activities: Engaging Standards Efforts Partnered with EDINA (UK) and NARA to approach the Open Geospatial Consortium (OGC) in Working Group charter approved by OGC Technical Committee plenary Dec. 2006

7 Unexpected Activities: Developing Ingest Workflow Tools Developed a set of Python classes for threat scanning, copy, item formation, and ingest object creation Developed a set of ArcGIS tools for format conversion Repository ingest approach gets inspiration from ECHO DEPository hub-and-spoke model

8 Huge new audience for geospatial content/services Massive crossover of mainstream IT to geospatial, spurring open source activities Rapid development of lightweight interoperability specifications “Good enough” approaches to data (formats, quality, standards) Changes in the Domain: Mashups, Google Earth, Map APIs, and More

9 Web mashup/AJAX interactions with existing systems spur creation of intermediate content layers: e.g., tiling and caching of web map services Ongoing development of a tiling services spec creates a new preservation opportunity Changes in the Domain: New Information Ecosystem of Static, Tiled Map Data

10 Mobile, LBS, and, social networking applications drive demand for place- based data Long-term cultural heritage value in non- overhead imagery: more descriptive of place and function Changes in the Domain: More Place-based (versus spatial) Data Oblique Imagery Street View Images DOT Videologs Tax Dept.
