Training Structure • Agenda • How do I share my information with others? • Overview of catalog implementation options • Implementation considerations • Catalog characteristics • EPA Implementation Example • Overview of Geospatial One Stop (GOS) • Materials • Metadata catalog comparison spreadsheet • Summary
Learning Objectives • After completing this module the student can: • Describe what types of catalog implementations are available • List some pros and cons of each option • Describe three key considerations for choosing a catalog implementation • Describe the features that GOS has to offer • Describe how to register a catalog at GOS
Internet / Intranet Data Set Metadata Catalogs and Sharing • How do I share my information with others? • Implementations • Website Catalog • Web Accessible Folder (waf) • Z39.50 metadata clearinghouse • Metadata Service • Geospatial Data Portal Internet User Query Metadata Collection
Metadata Catalogs and Sharing • Catalog Implementation Considerations • What are your needs? • Ease of implementation and maintenance? • Freeware? • Integration with COTS products? • Large-scale, robust enterprise catalog? • Advanced administration & management? • Contribute to NSDI and GOS? • Others?
Catalog Characteristics • Website Catalog • Simple framework; usually not a lot of overhead to maintain* • Users do not need special tools for access • Usually easy to use with browse access for data layers • May not require special software to implement • Static pages may not be suitable for large collections of data • May not readily lend itself to sharing with other catalogs Example from MassGIS website * If you have a lot of data/metadata that change frequently this option may not be simple to maintain
Catalog Characteristics • Web Accessible Folder (WAF) • Simple framework; not a lot of overhead to maintain • Users do not need special tools for access • Does not require special software • Interface may not be intuitive for various users • May want to customize for ease of use • EPA Example: http://geodata.epa.gov/WAF/ • Readily lends itself to sharing with GOS & NSDI
Catalog Characteristics • Z39.50 metadata clearinghouse • Typically relatively simple to set up and maintain • Works with both the NSDI Clearinghouse and GOS • A web based interface should be developed for human interaction • Can be implemented using freeware • Isite software is free; • GeoNetwork is open-source • ESRI’s ArcIMS Metadata Service can be configured to use Z39.50 connector • More Information: • http://www.fgdc.gov/dataandservices/getisite • http://www.loc.gov/z3950/agency/
Catalog Characteristics • Metadata Service • May require more overhead and software/hardware to set up and manage • Users may need special tools for access unless a web based interface is created for interacting with the service • Usually readily accessible from ArcCatalog • Provides browse capability for records • Usually readily lends itself to sharing with other catalogs and clearinghouses • Requires special software; a common implementation is the ESRI Metadata Service which comes with ArcIMS.
Catalog Characteristics • Geospatial Data Portal • Requires the most overhead and software/hardware to set up and manage • Usually includes the most powerful tools for metadata management • Group access • Distributed management tools • ‘Harvesting’ • Usually readily accessible from ArcCatalog • Readily lends itself to sharing with other catalogs and clearinghouses • Requires special software; common implementations include ESRI Geospatial Portal Toolkit and GeoNetwork • Some Examples: Geography Network, Geospatial One Stop, EPA’s GDG, Conservation GeoPortal
EPA’s GeoData Gateway • Catalog Implementation Example • EPA’s GeoData Gateway (GDG) • Implemented initially in 2006 • Key out of the box capabilities • search • user management • map viewer • harvesting • ArcCatalog integration • Customized to meet EPA’s needs • Group Management • Single Sign On • Record-level security (external access) • Additional Considerations • Policies and procedures • Communication, outreach & training
EPA’s GeoData Gateway Demonstration
The GOS Portal – www.geodata.gov • What is GOS? • An intergovernmental project supporting E-Gov initiative seeking to: • Encourage collaboration • Leverage geospatial resources and best practices • Improve geospatial resource access, re-use and sharing • Resources available at GOS • Live Data and Maps • Downloadable Data • Offline Data • Documents
The GOS Portal – www.geodata.gov • What features does it offer? • Search & Discovery • Access Resources • View Data Services • Browse Communities • Post data acquisition plans • Publish metadata • Manage Metadata
Registering with GOS • How do I publish to GOS? • Create an account • Publish metadata • Harvesting • Online Metadata Creation Form • Online Upload Metadata File Utility • Manage metadata
Registering with GOS • Harvesting Options: • Z39.50 server • Open Archive Initiative for Harvesting Protocol (OAI-PMH) • ArcIMS Metadata Server • Web-accessible folder (WAF) • Catalog Service for the Web (CS-W)
Registering with GOS • Publishing Options • Online Metadata Creation Form • Stores metadata at GOS • Online Upload Metadata File Utility • XML or SGML
Registering with GOS • Manage Metadata • Publishers manage their own collections • View records • Download • Edit • Delete • Check online linkage • Transfer ownership
Metadata Catalogs and GOS • FGDC NSDI Components • http://www.fgdc.gov/components • GOS • http://www.geodata.gov • NSDI Clearinghouse • http://clearinghouse1.fgdc.gov/ • EPA’s Public Website and Metadata Service • http://geodata.epa.gov • Z39.50 • http://www.loc.gov/z3950/agency/ • GeoNetwork • http://geonetwork-opensource.org/ • ESRI Portal Toolkit • http://www.esri.com/software/arcgis/gisportal-toolkit/index.html
Registering with GOS • Metadata Catalogs and GOS Quiz! • Name one benefit and one drawback of implementing a geospatial portal as opposed to implementing a website catalog • Contents at a Web Accessible Folder (WAF) can be readily viewed through ArcCatalog • True • False • At GOS, a user cannot: • Search for geospatial resources • Access geospatial resources • Post data acquisitions • Purchase data using a debit card
