Norcross, US: ERDAS released a new version of ERDAS ECW/JP2 SDK, Version 4.2. It enables software developers in rapid and efficient file handling in the applications they create by including support for selected wavelet compression formats and protocols.
The ERDAS ECW/JP2 SDK supports visually-lossless Enhanced Compression Wavelet (ECW) imagery format and the ECWP protocol. ERDAS’ ECW technology compresses bulky imagery files into manageable sizes. It enables faster processing and transfer of imagery and reduces the hardware investment required for the geospatial workflow. Additionally, multi-resolution level of detail is built into the file, eliminating the need to generate or distribute pyramids or overviews. Enhanced Compression Wavelet Protocol (ECWP) allows streaming of ECW images, enabling rapid delivery of large quantities of imagery over the internet to thousands of users with standard server hardware of just eight cores or less. The SDK also provides support for the numerically-lossless JPEG2000, an ISO-certified compressed image format commonly used for geospatial imagery.
Mark Sheridan, Development Manager for the ECW SDK and Image Web Server, ERDAS, said, “Using ECW and ECWP, applications can compress, decompress and transfer files extremely fast with very little memory and standard server equipment, imparting a comprehensive cost reduction that other formats just cannot offer.”
New for Version 4.2, the ERDAS ECW/JP2 SDK is being offered as three different editions, with tool sets targeted specifically for either desktop or server applications.
