Washington, USA., 7 August 2006: LizardTech, a division of Celartem, Inc., and a provider of software solutions for managing and distributing digital content, announced on August 7 the release of GeoExpress 6.1 at the 2006 Annual ESRI International User Conference held at the San Diego Convention Center. This updated version comes equipped with non-uniform color balancing, geography markup language (GML) for JPEG 2000 (JP2) support and enables users to easily load imagery directly into Oracle Spatial via the GeoExpress graphical user interface (GUI).
Known for taking imagery beyond compression with a robust suite of image editing and manipulation tools such as multi-resolution mosaicking and image reprojection, GeoExpress now offers non-uniform color balancing for even quicker and easier distribution of raster imagery. As part of the current workflow, automatic or manual adjustments for color balancing allow customers to control brightness, contrast and histograms for each color band within an image. In mosaics of tiled images, in addition to applying corrections uniformly across a tile, GeoExpress 6.1 adds the option to make non-uniform corrections within tiles such as for tilt and vignetting.
Additionally, GeoExpress 6.1 allows GML metadata to be added to JPEG 2000 imagery in conformity to the new Open Geospatial Consortium (OGC) GMLJP2 standard. “This is an exciting update for our customers,” said Jon Skiffington, product manager, “because prior to the adoption of GMLJP2, the lack of a geospatial metadata standard meant that applications and viewers may not have been able to read geospatial metadata in a JPEG 2000 file. The expanded use of GMLJP2 will help advance the adoption and interoperability of JPEG 2000 as a geospatial image format.”
Another key feature of GeoExpress 6.1 is its integration with LizardTech’s Spatial Express application. Customers are able to optimize their investment in their Oracle Spatial 10g, an option to Oracle Database Enterprise Edition, by storing raster imagery natively in MrSID and JPEG 2000 formats. Spatial Express allows users to reduce the storage space used for raster imagery by up to 95 percent while retaining visually lossless image quality. In addition, they can now select an Oracle database and table to output to directly from within the GeoExpress GUI, making it easier than ever to load MrSID and JPEG 2000 imagery into Oracle Spatial. Thanks to LizardTech’s industry-standard MrSID geospatial image compression format and the ISO standard JPEG 2000 format, customers can store, manage, and access images that are hundreds of gigabytes in size more efficiently from within their Oracle database.
The GeoExpress 6.1 product family consists of an Unlimited Edition that includes the Tools suite and unlimited image compression functionality; a Standard Edition that includes the Tools suite as well as an allotment for image compression; and a Tools Edition for a low cost, powerful edit-only application where image compression is not required. A license server is also available which permits the management of “floating” GeoExpress licenses for distribution among team members who periodically need access to the software.
