ERDAS Releases ECW for ArcGIS Server

Based on technology originally provided in ERDAS ECW/JP2 SDK version 4.2, ECW for ArcGIS Server enables ArcGIS Server to support ECW imagery, providing the fastest decompression available. Using minimal memory, ECW can quickly decompress and open massive files, in many cases faster than uncompressed imagery can be opened. Additionally, multi-resolution level of detail is built into the file, eliminating the need to generate or distribute pyramids or overviews. The ECW technique does not require the creation and storage of intermediate tiles (RRDs), as they are an inherent part of the ECW format. ECW also supports opacity channels, allowing images to overlay other imagery cleanly without showing compression artifacts around the edges.

Initially introduced in April 2011, ECW for ArcGIS Server was greeted enthusiastically by the market, prompting this new release which extends the original capabilities. A key enhancement in ECW for ArcGIS Server version 11.0.2 is backward compatibility with ArcGIS Server 9.3 and 9.3.1 in addition to the previously supported ArcGIS Server 10. ECW for ArcGIS Server version 11.0.2 also supports the use of European Petroleum Survey Group (EPSG) codes in ECWP.

ECW for ArcGIS Server expands the industry-wide level of support for the ECW format. ECW is already supported in traditional desktop GIS, CAD and remote sensing packages, including ERDAS’ portfolio of products, as well as Intergraph’s such as GeoMedia®, . In addition, ECW is also supported in ArcGIS® for Desktop, AutoCAD®, Blue Marble Desktop®, ENVI®, Geomatica®, LizardTech®, GeoExpress®, FalconView™, Global Mapper, MapInfo®, Manifold® System, MicroStation®, and Smallworld™.

“ERDAS created ECW for ArcGIS Server in response to overwhelming user demand. For any geospatial organization requiring an accelerated workflow and reduction of hardware costs, ECW is the compression format of choice,” said Paul Beaty, Senior Technical Product Manager, ERDAS. “Its popularity stems from the fact that it doesn’t merely compress files; it simplifies their handling by making them faster to decompress and transfer. ERDAS is committed to providing rapid geospatial data delivery for organizations using any software platform. “
