NDIIPP Partners Meeting January 17, 2007

• 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

• 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

• 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Superceded USGS Topo Maps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

• 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 ContentExchange Networks

Orthophoto“sneakernet”system

Started fall 2006 Transportation data exchange system

Funded starting fall 2006

Ongoing statewide data inventory

Started March 2006

Unexpected Activities:Engaging Standards Efforts

• Partnered with EDINA (UK) and NARA to approach the Open Geospatial Consortium (OGC) in 2005-2006

• Working Group charter approved by OGC Technical Committee plenary Dec. 2006

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

• 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

• 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

• 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
