FGDC Content Standard for Digital Geospatial Metadata: Extensions for Remote Sensing Metadata

Topics covered How the standard was produced Public outreach What the standard contains

Motivation Compared FGDC metadata standard with ECS core metadata (release 2.0, 1994) Identified several categories of ECS metadata not clearly supported in FGDC standard

Beginnings Proposal submitted January 1999, approved April SWG designated Imagery Subgroup for development Project development team –All members of Imagery Subgroup invited –Additional members added

Development Cycle Initial draft by NASA/NASA-support members of team Three Project Development Team (PDT) review cycles: –Distributed for review –Discuss review at meeting –Revised on basis of review Meeting with ISPRS and NIMA people on varieties of sensors Revisions after meeting sent to team for approval

Development Team (not all members every cycle) NASA NASA Support - RITSS/GMU, SGT/GST, CSC USGS NIMA Lockheed Martin U. California (Santa Barbara) ISPRS - intend to use as base for ISO standard Material from U. Alabama (Huntsville)

External Awareness of the Standard Presented or briefed at professional conferences and meetings: –Digital Earth Symposium– 12/1999 –CEOS Working Group on Information System and Services (CEOS-WGISS) Meetings – 4/2000, 9/2000. –ISPRS Congress 7/2000. –OGC Technical Committee Meetings. –ISO Imagery (19121,4) and Metadata (19115) projects Copies of draft sent to CEOS-WGISS, ISPRS WG II/4, DGIWG, ISO Imagery project, and experts from China, Japan, and European countries.

Extended elements Identification Information –Dataset identifier,aggregations, names, references Data Quality Information: Algorithm and Processing Spatial Data Organization Information –Additional raster description elements Spatial Reference Information: Georeferencing Entity and Attribute Information: Scaling

New elements Platform and Mission Information –Identify potential coverage Instrument Information –Sweep scan –Frame Camera –Other (extensible)

Final Review After final Project Development Team meeting and revision, sent to Imagery Subgroup Responded to Imagery Subgroup comments Revised standard sent out with query for objections Approved by SWG February 21, 2001

External Review Plan Once FGDC approves release for public review, in addition to regular FGDC channels, draft will be submitted for comment to the following groups: –CEOS WGISS –ISPRS WG II/4 –ISO Imagery components, Model Harmonization Team –ASPRS –OGC Metadata, Image Coordinate Transform groups Presentation or briefing at professional meetings. –CEOS WGISS (May 2001) –Digital Earth (June 2001)
