Federal Geographic Data Committee (FGDC); Public Comment on the
Proposal to Develop the ``Spatial Data Transfer Standard (SDTS) Part 5:
Raster Profile With Basic Image Interchange Format (BIIF) Extension''
as a Federal Geographic Data Committee Standard
ACTION: Notice; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FGDC is soliciting public comments on the proposal to
develop a ``Spatial Data Transfer Standard (SDTS) Part 5: Raster
Profile with Basic Image Interchange Format (BIIF) Extension.'' If the
proposal is approved, the standard will be developed following the FGDC
standards development and approval process. If the standard is adopted
by the FGDC, it must be followed by all Federal agencies when
appropriate for the transferring of raster data directly or indirectly,
through grants, partnerships, or contracts.
In its assigned leadership role for developing the National Spatial
Data Infrastructure (NSDI), the FGDC recognizes that the standards must
also meet the needs and recognize the views of State and local
governments, academia, industry, and the public. The purpose of this
notice is to solicit such views. The FGDC invites the community to
review the proposal and comment on the objectives, scope, approach, and
usability of the proposed standard; identify existing related
standards; and
[[Page 42591]]
indicate their interest in participating in the development of the
standard.
Project Title: Development of Spatial Data Transfer Standard (SDTS)
Part 5: Raster Profile with Basic Image Interchange Format (BIIF)
Extension.
Proposal Date: March 24, 1997, Revised June 4, 1997.
Submitting Organization: FGDC Subcommittee on Base Cartographic
Data (SBCD).
Point Of Contact: John Crowe, USGS/NMD Raster Data Standards
Coordinator, (703)648-5596, jcrowe@usgs.gov.
Objective: The objective of this project is to develop a profile of
SDTS, through the convergence of the Draft FIPS Part 5 Raster Profile
of SDTS and the ISO/IEC Committee Draft 12087-5 Basic Image Interchange
Format (BIIF) raster transmission standards. This Raster Profile with
BIIF Extension, will expand the applicability of the SDTS raster
profile to broaden the utility of the SDTS transfer format, providing a
vehicle to enhance data sharing and to reduce redundant data
production.
Scope: The SDTS Part 5 Raster Profile with BIIF Extension contains
specifications of a profile for use with geo-referenced two dimensional
raster data, and excludes vector data and three dimensional and higher
dimension raster data. It is intended to provide a common transfer
format to be used for interchange of raster image and raster grid data
among all members of the data producer and user community. This profile
is intended to replace the existing Draft FIPS SDTS Part 5 Raster
Profile. The SDTS Part 5 Raster Profile with BIIF Extension falls into
the ``Transfer Standard'' type as defined by the FGDC Standards working
Group (SWG) Standards Reference Model.
Justification/benefits: This profile will provide a common transfer
format, independent of technology, to enhance data sharing for raster
data. The inclusion of a BIIF extension in this SDTS profile provides
an extended data format providing a container for raster, symbol, and
text, along with a mechanism for including image-related support data.
This profile will apply directly to two dimensional digital elevation
data (X-Y with Z as an attribute) and digital orthoimagery, two key
components of the National Spatial Data Infrastructure framework. It
will enhance data useability by providing a foundation for
interoperability in the interchange of raster data among diverse
applications.
The inclusion of BIIF capabilities in SDTS Part 5 provides the
benefit of an extended data format. This satisfies the following
requirements:
1. Provides convergence of civil and military raster standards.
2. Provides a means whereby diverse applications can share imagery
and associated information.
3. Allows applications to exchange comprehensive information,
allowing users to select only those data items that correspond to their
needs and capabilities.
4. Minimizes pre and post processing of data.
5. Minimizes formatting overhead, particularly for applications
exchanging a small amount of data over bandwidth-limited systems.
6. Provides Transportable File Structure (TFS) as a mechanism to
exchange PIKS image and image-related objects.
7. Provides extensibility to accommodate future data, including
objects.
Approach: Starting with the existing Draft FIPS Part 5 Raster
Profile of SDTS and the most current version of BIIF, build an SDTS
profile which provides the best of both standards for transferring two
dimensional raster data while maintaining backward compatibility to
existing raster profiles. The BIIF extension will be integrated with
the existing Draft FIPS Part 5 Raster Profile of SDTS as an optional
encoding of image data to include both raster grid and raster image
data. The final product will be a profile which maintains the archival
capabilities and focus of SDTS with optional extensions to allow
inclusion of the imagery transmission focus of the BIIF. The BIIF
extension provides a container for raster, symbol and text as well as a
mechanism for inclusion of image related support data. The expanded
capability of the new SDTS Part 5: Raster Profile with BIIF extension
will broaden the applicability of the SDTS. The FGDC will provide the
vehicle for wide participation and input from across the raster data
user and producer communities.
Related Standards: Related standards which were used as reference
in building the new SDTS Part 5: Raster Profile with BIIF Extension
include the following. These standards will retain this relationship
and may be used as reference, although they will be unaffected by the
adoption of the proposed SDTS Part 5: Raster Profile with BIIF
Extension.
ISO/IEC 12087-5--Information Technology Computer Graphics and Image
Processing, Image Processing and Interchange Functional Specification

The following standard, and profile, were used as reference for
building the new profile. The SDTS Part 5: Raster Profile with BIIF
Extension is intended to replace the current Draft Part 5: Raster
Profile of the FIPS 173 SDTS Standards.
FIPS PUB 173--Spatial Data Transfer Standard (SDTS) 28 August 1992
Spatial Data Transfer Standard (SDTS)--Part 5, Raster Profile (Draft)
Both of the following Draft FGDC Standards currently point to the
FIPS 173 Draft Part 5: Raster Profile of SDTS. If the proposed SDTS
Part 5: Raster Profile with BIIF Extension is adopted, both will be
modified to point to the new profile.
FGDC Draft Data Content Standards for Digital Orthoimagery (January
1997)
FGDC Draft Data Content Standards for Digital Elevation Data (January
1997)
Schedule: The SBCD will review the draft SDTS Part 5 with BIIF
Extension in June of 1997. The SBCD will then submit the draft to the
FGDC Standards Working Group (SWG) in July 1997. It is hoped that the
SWG will review the draft, with the goal of determining its suitability
for public review, in an expedient fashion. Once approved, the standard
will be in public review for a minimum of three months.
Resources: The Raster Convergence Working Group has provided
development resources for the preparation of the initial draft standard
and will provide resources to assist in the adjudication of comments
from the public review and approval process. The SBCD will provide
additional resources to promulgate this standard through the FGDC
standards development process.
Potential Participants: The primary participants in the development
of the profile include NIMA and the USGS.

Other contributors include the Joint Interoperability Test Command
(JITC), the BIIF editorship, Geomatics Canada, the National Oceanic and
Atmospheric Administration (NOAA), the National Geodetic Data Center
(NGDC), and the Digital Geographic Information Working Group, which
represents the Digital Geographic Information Exchange Standard
(DIGEST) under the auspices of NATO. The membership of the SBCD will
provide a broad sponsorship for this standard. The public review and
comment period will include an aggressive program of outreach to ensure
a broad level of participation from the geospatial data community. Any
of the contributing bodies mentioned above may be called on to
participate in the adjudication of public review comments and the
redrafting of the standard. There is also potential to include
representatives of the commercial/private sector, State and local
governments, as well as the academic community in the continuing
development of this standard.
Target Authorization Body: The FGDC Steering Committee is the
initial target authorization body for this standard. Once endorsed by
the FGDC the intent is to seek ANSI endorsement of this standard.
