EPA GIS Workgroup - Metadata National Geospatial Overview: Metadata EPA GIS Workgroup Meeting Fall 2004 Las Vegas, NV

EPA GIS Workgroup - Metadata FGDC and GOS Metadata • Compliant metadata, richly informative • Metadata Repositories • GOS partnership

EPA GIS Workgroup - Metadata Complaint Metadata • More than CSDGM Sections 1 and 7 • Tools to help – CSDGM Graphic Representation • http: //biology. usgs. gov/fgdc. metadata/ version 2/ – Metadata Parser aka “MP” • http: //geology. usgs. gov/tools/metadata /tools/doc/mp. html • Web, batch, and desktop apps available • Checks syntax/format not content

EPA GIS Workgroup - Metadata Richly informative metadata • Metadata Quick Guide • http: //www. fgdc. gov/metadata/education/Metadata. Quick. Quide. pdf

EPA GIS Workgroup - Metadata Repositories • Z 39. 50 – Centralized • National Park Service – Centralized with program/agency identity – Distributed • Arc. IMS Metadata Service • Web Accessible Folders (WAF) • OAI Initiative (library) EPA Metadata Sites The Urban Environmental Monitoring and Assessment Program Enviro. Facts Estuaries Data Group

EPA GIS Workgroup - Metadata GOS Partnership • Register – Publish – – – – Publisher Geographic datasets Images Geoservices Spatial solutions Reference material Events and activities Geodata Partnership Opportunities – Schedule NSDI node – Metadata harvesting

EPA GIS Workgroup - Metadata GOS Metadata Harvest • How to contribute metadata: – Register existing metadata collection for harvesting, specify frequency and time. Arc. IMS Server, Isite/ Z 39. 50, WAF or OAI – Upload metadata as CSDGM XML to the geodata. gov site – Enter metadata into a form at geodata. gov where it will be stored and indexed

EPA GIS Workgroup - Metadata Enabling Harvesting Keyword Crosswalk

EPA GIS Workgroup - Metadata Harvest A scheduled automated process for collecting new and updated metadata from a variety of metadata repositories • First retrieval- all metadata validated. Those containing GOS required content posted to geodata. gov • Previously harvested- only updated metadata retrieved • Validation – Requires GOS minimum metadata – Uses FGDC metatags for validation

EPA GIS Workgroup - Metadata GOS Required Metadata Content • • • Originator Metadata Date Title Abstract Purpose • • • Time period Progress Maintenance Bounding Box Keywords Information Derived from Registration*: Contact Person or Organization Address type, Address Phone number Email *When using online metadata form

EPA GIS Workgroup - Metadata GOS Metadata Validation. Metadata Parser (MP) • Error reports forwarded to agency – “Errors” to be remedied – “Warnings” acceptable • Metadata with errors are not posted to geodata. gov – Once errors are corrected, schedule for harvest – Common errors: • Currentness Reference- null (ground condition, publication date, ”free text”) • date format- YYYYMMDD (YYYY minimum)

EPA GIS Workgroup - Metadata Registering IMS or WMS • Using agency metadata tool and repository: – Create metadata describing service, enter address in “Online Linkage” and post to agency clearinghouse • On geodata. gov – Login – Go to publish a new record – Enter map service address
