Question

What is required to serve ECW images in ArcGIS Image Server?

Answer


 The ECW raster format is directly supported in ArcGIS Desktop, but not in ArcGIS Server, ArcIMS, or ArcGIS Image Server (the ArcGIS Server Image Extension). To use ECW in server-based products requires additional licensing permissions from ERDAS, Inc., the inventors of the ECW format.


For ArcGIS Server version 10, ERDAS provides the ECW for ArcGIS Server product. Once obtained, follow the product's directions to implement.

For versions prior to 10, contact ERDAS to request a license. Once the proper licensing is obtained follow the remaining directions. It is necessary to install several files and run a setup to configure the Service Editor and service providers.

There are three DLLs required for ArcGIS Image Server to use ECW files. These are:

• NCScnet.dll
• NCSEcw.dll
• NCSUtil.dll

These binaries can be obtained from ERDAS, Inc. (www.erdas.com) after purchasing a license for server-side use of the SDK.

Download and unzip the ECW.zip and run the ECW.msi. This installs the additional required files to support the ECW format in ArcGIS Image Server.

 These procedures allow access to ECW files. However, they do not allow data delivery by way of high-speed ECWP streaming imagery protocol.


 For more information, or further directions, see the InstallingECWplugin.doc or README.txt documents contained in the ECW.zip.
