ERDAS proudly announces the introduction of the all-new ECW for ArcGIS Server, which provides a means for ArcGIS Server 10 to deliver Enhanced Compression Wavelet (ECW) data to clients via OGC-compliant Web Coverage Service (WCS) and Web Map Service (WMS).

Using components of the 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 that immediate tiles (RRDs) be calculated and stored on disk; they are an inherent part of ECW’s Discrete Wavelet Transformations (DWT). ECW also supports opacity channels, allowing images to overlay other imagery cleanly without showing compression artifacts around the edges.

The ERDAS ECW/JP2 SDK technology was developed by ER Mapper Ltd beginning in 1998 and is governed by three patents (US6201897, US6442298, and US6633688).

ECW for ArcGIS Server may be installed on a single ArcGIS Server, with or without other ERDAS software installed. However, ECW for ArcGIS Server does require a FlexNet license file from ERDAS.

This new product expands the industry-wide level of support for the ECW format. ECW is already supported in traditional desktop GIS, CAD and remote sensing packages such as ArcGIS, AutoCAD, ERDAS IMAGINE, ERDAS ER Mapper, FalconView, Bentley Microstation, ENVI and PCI Geomatica.

“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, 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. “

To learn more about ECW for ArcGIS Server, please visit the official product page or attend a free ERDAS webinar on Wednesday, April 13, 2011 at 11 am or 7 pm (GMT -4).
