1959 1974
When librarians managed books, cartographers maps, and programmers bits and bytes

- - --------------------------------------------------------------------------------- Purpose:
Inventory of Louisiana digital coastal data
Partners: LA state government and coastal research community
Sponsor: US Geological Survey
Purpose: Inventory and collection of oil spill contingency planning information resources
Partners TX, LA, MS, AL, and FL Natural Resource agencies
Sponsor: Bureau Ocean Energy Management, Regulation and Enforcement (BOEM fka MMS)
Purpose: Establish web catalog to publish and locate information about national geospatial data assets
Partners NSDI Stakeholder Community (all levels gov, tribal, private sector, NGOs, university, and other)
Sponsor: Federal Geographic Data

---------------------------------------------------- Louisiana Coastal GIS Network (LCGISN)
What Worked -----------------------------------------------------------------------------------
• Broader scope (Fed) and $ponsor
• Outreach and initiation of digital
coastal data community of practice
• Focus on data (vs findings) = new
perspective - data as corporate asset
• Inventory process seeds practices:
- data documentation
- data sharing
• Coordination with library scientists
What Didn’t
• Coastal researchers leading data
management project, e.g.:
- Structuring data for store/retrieve
- keywords
• Authoritarian ‘give us your data’
approach
• Lack of standards
• Documenting other people’s data

---------------------------------------------------- Gulf-wide Information System (G-WIS)
What Worked -----------------------------------------------------------------------------------
• Broader scope (Fed) and $ponsor
•Mission-specific focus
oil spill contingency planning:
- codified data requirements
- kindred organizations performing
same task
• Data compilation by single source
with task-specific expertise:
- content/format consistency
- project focus on data sharing vs.
development
What Didn’t
• Coastal researchers leading
complex data management project,
same data for different:
- geographies (states)
- time periods (collection & update)
- design relative to use
• Single geography for region
- multiple projections and datum
- state boundary gaps
• Centralized data storage

----------------------------------------------------
What Worked -----------------------------------------------------------------------------------
• Federal leadership – provide infrastructure vs funding
• Use of standards - Z39.50 - metadata
• Bottom up empowerment approach, e.g. network of self-managed nodes
• Education and outreach - workshops, guidance
documents - Don’t Duck Metadata - CAP funding
What Didn’t
• Unfunded mandate
• Perception that metadata is written
so others can discover/use your
data
• Node installation and maintenance
requirements (minor issue)
Incorporate Into the Business Practice establish responsibility via assigned tasks, policy, and guidelines support by allocating resources: time, $, staff and involve the right experts early set expectations via performance measures manage data as capital asset and incorporate data lifecycle planning
Use Standards
metadata protocols data models and workflows thesauri, spatial references…
participate in standards development & update – advocate for change before going your own way

Outreach & Educate
be open - facilitate input at all levels provide training develop guidance and reference docs have fun (when you can): contests, logos, awards, etc.
Focus on Implementation
design for and pilot with users decentralize / empower contributors emphasize benefits to contributors (vs users) make metadata, QA/QC, and publication part of the process distribute the effort, e.g. data management role at each stage: collection, analysis, QA/QC, review, etc.
