This out of Seattle this morning… The new GeoExpress SDK Supports 64-bit Platforms for Both MrSID and JPEG 2000… providing developers better compatibility with GDAL and other third-party libraries along with access to more memory than before when working with MrSID and JPEG 2000 imagery. Improved documentation and sample applications for this release are expected to make it easier for developers to integrate with third-party applications. see http://developer.lizardtech.com.
