Lossless capabilities allow faster analysis and visualization of original source imagery.

Lizardtech Software and Leica Geosystems announced support for Lizardtech's lossless MrSID technology into Leica Geosystems' ERDAS IMAGINE product line. The latest mapping software vendor to support Lizardtech's next-generation lossless technology, Leica Geosystems' ERDAS IMAGINE users now will be able to quickly and efficiently view and store original-quality imagery for feature classification, military applications, or other mission-critical mapping uses.

Incorporated into the recently released GeoExpress with MrSID version 3.0, lossless MrSID preserves images with pixel-for-pixel fidelity in a greatly compressed format-easily reusable in future applications. Once in lossless format, MrSID imagery can be re-purposed for fast easy distribution at any compression ratio.

Said Karen Morley, director of product management, geospatial imaging, at Lizardtech, "Many of our customers are using Leica Geosystems' products for image analysis and exploitation. The new Lossless MrSID file format will allow them to achieve greater accuracy while performing functions such as classification."

"We are excited to be able to extend the benefits of incorporating lossless MrSID technology to our customers who use ERDAS IMAGINE," said Ian Anderson, Senior Product Manager, Leica Geosystems. "With this added functionality, our customers can save processing and viewing time while retaining critical image accuracy requirements."

ERDAS IMAGINE products supporting both the latest lossless and previous versions of MrSID include versions 8.6 (released Dec. '03) and 8.5. IMAGINE MrSID lossless support is immediately available via a downloadable .dll file from the Leica Geosystems Web site. Future ERDAS IMAGINE releases will incorporate native viewing for both MrSID Generation 2 and Generation 3 image formats.

Lossless Encoding Increases Image Accuracy Lossless MrSID is wavelet-based imaging technology that dramatically increases the value of geospatial data by making it more accessible and useful while maintaining the highest level of quality and accuracy. Lossless technology maintains numeric pixel fidelity between original and encoded imagery, enabling geospatial imagery to be used in new applications, on more devices and across more networks. In addition, it provides dramatic reductions in the cost of storing, sharing and using geospatial information.

Automatic Mosaicking Saves Image Creation Time In addition to the lossless data capability, advanced mosaicking features included in GeoExpress allow users to easily create a single mosaic automatically from multiple sources. In an industry-first, organizations that update imagery, such as governments, data providers and civil engineering firms, will be able to update existing MrSID mosaics without re-encoding. They will also be able to mosaic existing tiled MrSID images into a seamless MrSID mosaic, automatically. Together, these benefits will save time and reduce storage needs.
