EPA’s Geospatial Metadata Framework
An Overview
FGDC Coordination Group Meeting February 12, 2008

2
Agenda
• Background – Drivers– Initial Efforts– Reason for Change
• Current EPA Metadata Suite
– Policy/Planning Framework– Users/Community– Technology
• Demonstration– GeoData Gateway– EPA Metadata Editor
• Lessons Learned
• What’s Next?

3
Background
• Drivers – Executive Order 12906– OMB Circular A-16– Intra- and Inter-Agency Sharing
Efforts
• Initial efforts had some problems– Dual system access for
internal/external
– All components not standards-based
– Information not synchronized
– No direct links to data
– Difficult to document metadata
– No direct management by users
– Lack of stewardship
• Result: Not widely used

4
Background
• Desire for Change– EPA decided it needed to organize geospatial metadata
• EPA Metadata Workgroup (2005)– Business Rules: Define EPA’s Implementation of FGDC CSDGM
» EPA Regions and Programs represented» Agreed to an implementation and resulted in EPA Geospatial
Metadata Technical Specification
– Architecture: Define baseline and target architecture» Baseline identified holdings in central and Regional websites
(over 4,000 holdings identified)» Target included a standards-based integrated, dynamic system

• Users/Community– Intense outreach in 2006/07
• Monthly stakeholder sessions• GDG/EME training• Presentations at major conferences• ESRI award & paper
– Groups working with us• 8 out of 10 Regions*• 6 out of 11 programs
Current EPA Metadata Suite
* All groups working with us may not have contributed records yet

• Technology Framework
– GeoData Gateway (GDG)• Central, standards-based system
that automates contributions and allows distributed users to manage their information.
• Single-Sign-On with EPA’s Central Identity and Access Management (IAM) System
• Automates contributions to GOS and NSDI
• Reusable components can be integrated with other applications
Current EPA Metadata Suite

10
• Technology Framework
– EPA Metadata Editor (EME) • Simplified interface integrated
in ArcCatalog
• Provides EPA Validation Service and database-driven defaults
• Used across EPA, states & other Feds
• Over 950 downloads since July 2007

Lessons Learned• There have been a few bumps along the way…..
– Adopting Relatively New Technology• Often first to discover bugs• Not a large user base to draw on
– Performance & Reliability• Image & feature services inconsistent within Map Viewer components• Sometimes things just ‘stop’ working
– Integration with larger EPA Architecture • Need Service Level Agreements• Need to understand new responsibilities placed on other system owners in
advance!
– Use of COTS Product• Customization always a risk
– User Buy-in is Key• If users bought into system and understand what’s needed, they often put up with
imperfection.

What’s Next?
• Implement Strategic Plan
– GDG Outreach• Focus on meeting consumer needs• Continue working with producers• Begin working with application developers
– GDG Technology Enhancements• Performance and usage monitoring• Other minor enhancements to improve user experience
– EME Technology Enhancements• Implement stakeholder feedback• Web-based version to replace GDG web front end• Implement validation web service at GDG
– Continue Integration with EPA IT Infrastructure• Evaluate and implement high-value integration efforts
– Develop Long-term funding plan
