JPEG2000 geo-location definition using GML is
backed by JPEG2000 leaders Algo Vision LuraTech,
ER Mapper, Kakadu Software, Morgan Multimedia
and Yakoa
Berlin, Germany, Sydney and Perth, Australia, Montpellier, France and Strathmore, Ireland May 2004
Leaders in JPEG2000 technology today announced their endorsement of a common way
to use GML schema for storing geo-location information for imagery, within the
JPEG2000 format. This definition is an open manufacturer agreement, based on the
proposal of Algo Vision LuraTech on GML inside JPEG2000, which has already been
adopted as a part of the standard.
Geo-location information is used to define the image's map projection, datum and
extents.
Algo Vision LuraTech GmbH, Kakadu Software, Earth Resource Mapping, Morgan
Multimedia and Yakoa have been actively involved in JPEG2000 since the very
beginning and have a common market share of more than 60%. Ensuring that
geo-location information is stored in a unified and non-proprietary way within
JPEG2000 using GML (Geography Markup Language) is an important step for the
geospatial industry.
The organizations have released a simple 3 page document explaining how to use
GML to store geo-location information in JPEG2000 files. The document includes
GML examples and a source code example to write JPEG2000 geo-location
information. JPEG2000 developers wishing to ensure that geo-location is recorded
in a consistent fashion can find the document at
www.ermapper.com/jpeg2000/standards/JPEG2000_Geolocation.pdf.
The paper will also be introduced to the JPEG2000 ISO committee, as the
definition makes GML part of the JPEG2000 file format. The definition was
already provided by Algo Vision LuraTech to leading industry organizations
including the European Union Satellite Center at the recent ISO conference on
JPEG2000 in Madrid, Spain. The industry embraces this agreement between the
largest and experienced JPEG2000 manufacturers, as interoperability is one of
the major issues.
Dr. Taubman, Author of Kakadu Software and a key contributor to the JPEG2000
standard, said "It is important to use existing standards. The JPEG2000 ISO
standard caters for XML formatted metadata. GML in turn is an XML schema.
Ensuring geo-location information is stored in a consistent way using GML means
that different JPEG2000 libraries can read and write geo-location information
regardless of which JPEG2000 library is used."
Stuart Nixon, CEO and founder of Earth Resource Mapping, added "There has
been some recent confusion in the market place about GML and JPEG2000. The
reality is simple: JPEG2000 supports GML metadata. This is due to Algo Vision
LuraTech's efforts some time ago. GML uses the standard EPSG definitions for
map projection and datum. This combined effort by JPEG2000 leaders simply
ensures that the minimal sub-set of GML needed to store map projection and
extents information is read and written in a consistent way by all products."
Guillaume de Bailliencourt, Lead Manager for Morgan-Multimedia, said "We
are pleased to be involved in this important process to ensure that JPEG 2000
libraries can all read and write geolocation information in the same way."
Dr. Ivan Fox of Yakoa said "The advantages in having a single, open and
standard approach to geo-location are clear. Yakoa supports this initiative as a
positive step forward for both customers and vendors alike".
Carsten Heiermann, Managing Director of Algo Vision LuraTech GmbH, said that
"Algo Vision LuraTech has been active in ensuring that JPEG2000 meets the
needs of the geospatial community. This definition will ensure interoperability.
Therefore we invite all other JPEG2000 vendors to join our initiative instead of
making their own proprietary definitions. It is important, that vendors of
JPEG2000 work together to achieve customers confidence in interoperability of
all geospatial JPEG2000 solutions."
About Algo Vision LuraTech GmbH
Algo Vision LuraTech GmbH is one of the leading developers of JPEG2000
implementations and technology for the compression of images, data and
scanned documents in color. Resulting from the 2002 merger of Algo Vision
Mediatec GmbH and LuraTech GmbH, the Berlin-based company became a
subsidiary of the Algo Vision Group. Algo Vision LuraTech is intensively
involved with international standardization committees such as the
International Organization for Standardization (ISO) and played a
significant part in establishing JPEG2000 as an international standard for
image data compression.
About Earth Resource Mapping
Earth Resource Mapping offers enterprise geospatial imagery solutions.
Clients in more than 120 countries use ER Mapper to prepare imagery, ECW
JPEG 2000 to compress and use imagery, the Image Web Server to serve imagery
over the Internet and RightWebMap for integrated web map solutions. Visit ER

About Kakadu Software
The Kakadu software is written by David Taubman, who was also the principle
author of the JPEG2000 Verification Model (VM) software. Dr. Taubman holds
the position of Associate Professor at the University of New South Wales. He
is a key contributor to the JPEG2000 standard and co-author (with Professor
Marcellin) of a comprehensive book on image compression and JPEG2000,
published by Kluwer Academic Publishers.
